Noone has discussed these yet. Ok so it's not a Dream. But what do you think the chances of usm getting a cuda gpu sdk? I wouldn't put it past nvidia to give every edge for graphics programing when every last drop of power will count for the (on the apx android not 600) 720p hd output. This will change wireless network security as we know it. Imagine how few phones you would need to crack most wireless security. We would be back to being as secure as only having wep (which is flawed).
now imagine the ability to sit in a busy area and hack phones with enabled bluetooth in the time it takes to... oh.... eat a meal... and now you can make calls from their phone to a toll number you setup. We may be a little ways off, but in the near future we are going to have to have to rethink encryption/security.
A single 8800 ultra card can break a 8 character md5 password with no dictionary/rainbow table in about 16 days. Even if the tegra's are not as powerful as the 8800 ultra yet, add dictionary or rainbow tables and some bluetooth clustering of some friends phones, and the 8800 ultra won't even compare.
Anyways, my $0.02. Noone had mentioned the tegra (maybe there is a different forum for generic android development?) I thought it might be interesting.
You don't "crack" md5 passwords, you find collisions for MD5 hashes that *could* be encrypted passwords, and I don't see what that has to do with WiFi/bluetooth security.
the point is not if md5 protects bluetooth/wifi. md5 is just the benchmark for how fast brute force cracking is with cuda. In fact the point is never to get the password, its to unlock what is protected. (from a crackers standpoint)
say we have a function - (password×3+salt (remove last digit)=hash) , we are keeping it simple.
we would know the salt, lets say 2
password,hash
1,0
2,0
3,3
4,3
5,3
6,4
...
this is extremely simple, but we are only looking to unlock the encryption, not find the password.
Anyways, im just saying we will be looking at programs which are able to hack both wifi and bluetooth quickly and from the palm of our hand, thanks to nvidia. our encryption is valid as long as it takes longer to crack it than iwould be useful aka encrypted message with orders saying japan will bomb pearl harbor only needs to be encrypted long enough to have the bombs drop. but we are becomming able to shorten this time tremendously and soon the power will be in our hand to hack security implementations which are not strong enough to keep secure what we need to keep secure the obvious targets with a handheld device being wifi/bluetooth
We are already able to hack wifi and bluetooth easily... not from our palm, but from our laptop.
WiFi (No fancy RADIUS stuff) is relatively easy to hack... all you need is enough client-logons sniffed, and you will be able to guess the password, you don't need that much processing power.
Anyway, the world won't go under because of the tegra... if the tegra can do it, any other device can (Even though your C64 might be a bit slower...).

By 8800 Ultra, do you mean the video card?
Either way, cracking an 8 character letter only lower case MD5 hash in 16 days would require 151,000 MD5 hashes per second.
I doubt even using the most optimised code, programmed entirely in native ASM, is that possible. I don't even think the new i7, utilising all 4 cores could achieve 151k hashes per second. I'd love to see some benchmarks for this.
(this is assuming, of course, that nVidia doesn't have some top secret MD5 algorithms built into the GPU that I'm not aware of).
Also, as said above this can all be done on a notebook. Not only this, but you could relay the info via 3G to a cluster of PC's dedicated to cracking it.
And on top of all of this... Android running Debian/Ubuntu is already capable of running aircrack. It may not be the fastest, but again... use the G1 to dump packets, upload it to your main quad core CPU to crack it.
This is nothing new. It may seem new, but ALL of this is already possible, and has been possible by just using remote servers and the data connection built into your phones.

CAN THE SHIFT STILL MAKE A SPLASH IN THE RIGHT DIRECTION?
To a lot of the community it must seem that the highpoint of the HTC Shifts anticipation was the Hugo Ortega review of the device back in August [Additional Video Link]. The community seemed to Match Hugo’s enthusiasm for the device at the time, and understandably; the device has the potential to take the UMPC and pocketPC platform a great leap forward and all, since its first revelation for sub $2000. But since that high note and as more details have trickled out about the Shift the enthusiasm from both communities (UMPC and Pocket PC) seems to have diminished in proportional response [Comments here offer a glimpse to some of the broad criticisms now circulating].
The HTC Shift isn’t the first device to have specification changes or features taken out along the production path. First to go has been the 1.2Ghz Processor, followed by Windows Mobile 6 (at least a full version), next was voice capabilities (its quite possible these were never going to be available but given the cellular functionality of the device one wonders), then went the hope for at least a 1024x600 resolution screen and lastly the most recent revelation is that we can expect only 2hours of Vista battery life [New specs link – thanks to Kaz covering first hand GITEX2007].
Now the above paragraph might make it seem that the HTC shift has been butchered from its original splendour, so lets take a look at these change and its general specs. This isnt a review of the device, I haven’t been blessed to try the device, its just my interpretations of where the Shift is at now as it prepares to ship, combined with my UMPC experience but mainly as a long time Windows Mobile user and HTC enthusiast.
Processor: so we’ve gone from 1.2Ghz Via Chip down to the Intel A110 Stealy 800Mhz. It’s not all bad news, it’s the same processor used by popular UMPCs such as the Samsung Q1 Ultra, and is increasingly be used by other UMPCs such as the Kojinsha and Fujitsu. Most users have reported things run smoothly on these platforms, including Vista so unless you’re planning on using your UMPC as a video encoder one might suspect its going to do the usual run of the mill UMPC stuff just fine with 800Mhz. Despite a slow boot up time (possibly an anomaly, possibly could be corrected with tweaks) the multi-tasking from the Ortega video appeared quite smooth and responsive.
Windows Mobile (WM): When it was originally reported that WM would ship on the device I was confused as to what could possibly be the advantages of such an approach. Samsung had already proven you could build a dialler and phone functionality into the OS so why waste time putting WM on there.
After seeing the video review it made perfect sense. Use WM to do the things you don’t need vista for or that WM can do due to its longer battery life. This seemed to make sense. Why boot up Vista with its limited lifespan when I could get plenty more WiFi, Media playing, Powerpointing, Emailing done right there in Windows Mobile. Leaving Vista for the higher end tasks such as work, proper editing, more in-depth outlook management, data management, and maybe even a game or two?
Unfortunately the latest news from GITEX 2007, and Kaz’s adventures there, seems to point to WM being nothing more than ‘an advanced BIOS with a modem (HSDPA) for push-email support’. I think this is a big mistake as crippling WM in such a way limits its potential to being just a weak sideshow feature to Vista. Whilst being able to access the weather information and get my emails from HSDPA is nice, I believe my vision of WM above would make more sense.
However, if its one thing WM communities have shown though is never say die when it comes to changing our devices to suit. Short of HTC limiting the WM partition or WM RAM, a sense of optimism for a cooked full version of WM might not be out of the question.
Voice Capabilities: HTC seem to have always taken the view that voice capabilities for this device do not exist. It seems to be a foregone conclusion, and whilst any feature is welcome, I question if anyone would truly replace their phone with this device had it the voice capabilities. Despite this its range of connectivity options and HSDPA is a leg above most UMPCs on the market.
The Screen: After Hugo’s review there were mixed interpretations of what native resolutions the device supported. This has been cleared up quite succinctly. The device will ship with 800x480. When questioned about using a lower resolution spec’d screen Middle East Operations Manager for HTC Kevin Chen had this to say:
‘The answer is simple. The screen is only 7" and since power consumption has to be low, HTC decided on the low resolution screen.’ [Source – Kaz’s Interview]
That answer actually makes the device sound sub-par, and whilst higher resolutions are always a nice treat there is something to be said along the lines of screen size. Releasing a device this late in 2007 with such a screen when the standard has clearly moved to 1024 is slightly disappointing but on the whole doesn’t diminish the device too much. As the CEO said it’s a 7” screen, 800x480 isn’t going to look shocking on that size device. People not use to an UMPC with a higher resolution are unlikely to be greatly phased, and (fingers crossed) the interoperated mode which upscales the screen to 1024x600 looked good on Hugos review. There is the distinct possibility that HTC may have got this right where other UMPC manufactures have persistently failed users.
HDD: The device now ships with a 40G drive and a 60G option, quite reasonable for the UMPC, but it has increasingly come under fire for not having SSD or at least the option. Whilst I agree the option would be nice, this is HTCs first foray into this market, especially in such a hybrid manner. I think it is understandable they haven’t opted for the SSD option due to simply not knowing how the device will go and what its profit margin will be in the end. SSD also runs against the prime criteria of this device, which from HTC seems to have been an extremely competitive price point. Whilst the exact price has not been confirmed, the places taking pre-orders are placing their bets on $1400-1600. SSD on average means an instant increase in price of $400-500 which would erode away any price edge HTC have over the competition with this device.
Battery Life: Despite being able to see alternatives or the upside of most of the specs and changes with the Shift I really can’t say I or anyone is impressed with 2 hours. Unless that is 2 hours with everything on and everything running non stop that one is left wonder where our 3hr standard went? Hugo reported 3Hrs in his review, and 3hrs is the least the community has come to expect from an UMPC. I’m not sure how HTC can reconcile this issue unless its 2 hours of maximum usability (ie everything on, everything being used for those whole 120mins). I would suspect it highly likely an XP version could be put on the device by the user (as it will not ship with XP) but whether this would increase the 2 Hrs significantly is unknown.
HTCs website for the shift says: “Why should I compromise?” and that’s an excellent question HTC, why should we compromise our UMPC experience with 2hours of battery life? I suspect you cannot win an UMPC argument armed with 2hours of battery life, and with that in mind I would ask them to answer that question for themselves. If the market has to answer it for HTC on this issue I wouldn’t be expecting a favourable outcome.[/b]
On the whole I think the majority of the Shifts specs are in line with current trends and what we might expect given the shifts criteria and this being HTCs first foray into such a market. But like most users the limited WM6 functionality diminishes my productivity hopes for the device, but I personally hold great hopes for the community to correct this. The battery issue is going to be a wait and see. One would highly suspect after 3 days with the device Hugo got a good idea of the battery life and if its turns out its 2hrs of maximum, full use than perhaps there’s hope, but just two hours in general falls too far short of the UMPC standard. In which case the Shifts splash is likely to be a painful bellyflop.
If this issue was however corrected or turns out to be the maximum usage or just a simple mistake than I see the shift being able to fulfil its role as an UMPC successfully. The device has unanimously been accredited the status of a sleek sexy, solid, well built device. The form factor, the potential of two operating systems and cpus make this a lethal device to the competition. The cellular options even without voice connect the device all the more.
HTC are playing a risky game delivering a device with these specs this late into 2007 where similar spec’d device have been out for some months now. As long as HTC can do something with the Battery life I feel confident the shift will still make a positive splash. Will it revolutionise the industry as first expected? Probably not. But it’s likely to still shake things up, in form factor, its connectivity options combined with the price point. The dual operating systems could also prove to be a big hit with the industry if they can function in a productive manner beyond the “limited version” were hearing about.
I had not been keeping up to date with the shift. If it is correct that there is no voice phone functionality then this device no longer has any potential for me. I was hoping to keep it around (big pocket, bag etc) and just use my bt headset to answer the calls. There is no way i will be carrying two devices on a regular basis, so if the shift can't call - I can't have it I still have hope because HTC have not removed the GSM from the description. Most people would take that to mean phone functionality.
All the other details are of less importance for how I intended to use it.
It seems the Shift is more of an UMPC than any hybrid in its current form. The cellular connections are all still there and the device can even recieve SMS based on the pics weve seen from GITEX however, voice capacities appear to have been removed/restricted.
Given the crippled version of WM included it seems HTC envision this as more of a UMPC than anything to do with a PocketPC which might entail phone functions.
That device was flawed from the beginning, 1) no call support on the windows mobile, 2) UMPC.
"After seeing the video review it made perfect sense. Use WM to do the things you don’t need vista for or that WM can do due to its longer battery life. This seemed to make sense. "
Brain dead, there's no sync between that windows mobile and vista(unless you use exchange which requires an internet connection*), and you'll have to carry a phone with you, so, why use the Shift to do what you can do on your really portable windows mobile phone?
*although broadly available it is a potential show stopper.
Get a 12" convertible tablet and a WM phone [period]
that's exactly what I have right now, but I just hate carrying two devices and even more I hate the time it takes to boot then connect through the phone. I just want to push on and use.

Well, If you see Hugo's video you know you'll take even more time to be up and ready with the Shift, even when resuming from hibernation like showed on the video, that thing isn't exactly an instant-on experience.
With a vista TPC you can resume from hibernation and connect through your WM device(in case you don't use a usb modem) much faster.
I also have that configuration I mentioned, tho it isn't a 12"(14"er), usb HSDPA modem - frees the WM device to do other things like moving away from the TPC w'out cutting its connection to the interwebs, and it also saves the battery of the WM device - and Trinity.
"I just hate carrying two devices"
It is really just the difference between the Shift's 7" and your 12" tablet since the WM device's weight and size is really irrelevant IMO.
The reason I say it makes sense to utilise the WM portion is because we don't all carry around 7" devices loaded with WM. Now the Advantage was fun to browse the web on and do everything else I listed, but the advantage is limited to being a WM device. The Shift has Vista to pick up where WM limitations kick in, or vice versa WM to kick in where UMPC battery life limits Vista.
I cannot help but feel people are expecting this device to be a notebook or tablet pc when its clearly an UMPC.
Apoc you list being an UMPC as its second flaw, its not a flaw its simply a fact of what the device is. Obviously if you want a bigger screen and a bigger device you'll carry around a tablet. However, there are those of us who want a small alternative to the tablet and this is it.
"Apoc you list being an UMPC as its second flaw, its not a flaw its simply a fact of what the device is."
Yeah, you're right.
resume/hibernate is not what I want. All my stuff is on truecrypt volumes and resuming breaks it. I would need to dismount each volume then mount it again after resume. I wanted a device that is always on but not necessarily doing anything. The way ppc wakes up when you push the on button or when a call comes in.
Anyway, the dream is over. I think the next best option is to find a small 3g card that will fit in my tablet with not much overhang. Telstra sell one but it is not on the correct band for my three account. Three's dongle looks like a mouse hanging out on its wire - not good.
You are right about the weight and size. What matters is the time. I use the devices at random times for short periods (20 minutes or less), If I have to spend 5 minutes getting ready then I could not be bothered to begin.
Another solution would be if the wm device could act as a modem even when off, the modem is not part of the windows hardware any way so it should be able to work. Unfortunately it does not. When I push the off button on the ppc my connection will last for about 30 seconds then disappears.
I wanted to break this off since the other topic was looking to be mostly about the LCD's

I wanted to see if the blank sockets on the system board were active. So I grabbed my multimeter and tested each pin to see if any delivered power. I don't know if these sockets are controlled by software, but it looks like these sockets are inactive.

I'm an electronics tech (avionics really) just so you know my background, and I am by no way a programmer i just hack my way throught when i need... poorly at that. I'm a long time reader but don't post much.
I havent taken mine apart yet, I bought it for the wife to use as an ereader she was using her evo before and already has bad eyesight I just dont think reading on that small screen is good for her. However we planned on returning it today because she couldn't get anything to work... But i loaded VAGAn-Tab rom on it and she likes it ALOT more now, but we still might be returning it (she thinks it to big and heavy to hold). So all I have to work with is the internal pics posted by other members and I thank you for them!
I was thinking about using a mini pci card with 3g/4g and GPS to solve my problem like this one for Sprint Customers looks very nice and they claim android support. Could someone please verify the length available for the card from the socket to the mounting holes? It should be around 50mm but i cant tell from the pic.
I cant post a link so google

M600_datasheet_v1.pdf
Then after more research I figured out that think I can get the GPS to work on the board. I found that the RXM-GPS-SG-T looks to be the exact chip they are using, the pin look to match exactly VCC, GND, RX, TX, RF, VOUT. So they are using an active GPS antenna (but could be modded for passive). They use NMEA-0183 or SiRF Binary output selected by a serial command. So we need to figure out if the TX is going to U39 making U39 the interface to the unit, or directly to somewhere else (idk need to see board) I hope i can attach my pic i made or maybe an admin can post it for me.
However the PCI slot might be just as hard to use, the pin 20 that has 3.3v isnt what we want, but it could be a software control to disable/enable the card. However we still need A+ on pins 2,52 (3.3V), 6,28,48(1.5V) and maybe 24(3.3V Aux) dependeding on the card. We could be dealing with a "Non Standard" connector, they are out there but most OEM's dont bother with them. More likely to find them on a Asus product ect. It's common for the SIM card to be powered by the PCI card itself and the board looks wired that way. I have 2 Digi International Mini PCI express Wifi/Cell Development boards and thats how they both power the SIM card. Pin 16 should goto Pin 1 on the sim card, 14->2, 12->3, 10->6 but maybe 7 or 8.
Getting the Power to it could be software or hardware. Looks like around U8 on the frontside could a Vreg setup, Or it could be as simple as putting in some 0 ohm resistors around R15 and R14. We also see that U7 is unpopulated on backside. So that leave us with U7,U8, R15, and R16 which could mean they are all part of the same circuit if they laid it out with any logic. TP1,2,and 3 also make me believe this is true, however they match up to LED_WPAN#, LED, WLAN#,and LED_WWAN#. I sure wish they match the power input pins, but that means all those missing resistors could just be for unpopulated status LED's. Like I've said over and over i cant tell ya unless i can probe around the board.
As far as the memory, yes its possible, I do BGA replacement at work. What I am afraid of is that the other memory chips look to be exactly on the other side and I'd be afraid of messing them up. I'd have to look at my jig at work and see if I could set it up without any problems.
I'm no electronics expert but I dabble. I'd be interested in internal GPS and a memory boost. I'm pretty confident in my soldering skills and would try something if directed by someone smarter than me.
This is something I am very interested in. Any new info on this?

I sadly no longer own a G tablet, wife thought it was to heavy to read books, and hated the screen. I cant argue with her on either of those points, so we returned it. However I got the ok to buy a referb on if i can find one, but when I did at my local store i showed them the paper and they told me they dont sell that stuff there and send me away. I talked to 3 different people too basically all told me to go f off. I even tried another time with the 7" they sell same results. I dont know why it gets listed on the website if they wont sell it.
Not to get sidetracked, but i even did by the proper bga fittings to solder the ram chips too lol..
So no its probably not going to go any farther from my stand point, if anyone wants my help I still read the forums everyday.
I'm just gonna wait and see what comes out in the future that XDA gets behind, because I'de never buy anything that didnt have an active community here.
IF you were looking for a reader fo rher mainly, you should've really gone with the Nook Color... eInk devices are good too IF you don't really need good PDF support and/or need it to read more complexly formatted documents, e.g. technical manual, mathematics texts, etc. i.e. eInk is best suited for ficiton and other simply formatted documents, but it VERY readable except in poorly lit conditions where you'd need external lighting of some sort.
Very true I should have bought her a nook, but now she doesnt want it because its not powerful enough for her needs imo. She also wants to login to her school (blackboard) and be able to use overdrive. Plus she likes dungeon defenders and I dont think that can handle it. We are just gonna wait it out and see what comes along, mostly cause we have our first due next month, so trying to be frugal.

Yep, you'll want a full blown tablet then and I suspect that the NC would be too much of a bother to get setup for her for what she wants it for...
All the 10" tablets are fairly heavy too, so you'll probably have to stick to looking for 7/8" tablets and I suspect Tegra 2 or multi-core cortex-a9 SoCs from other mfgs... not much in the way of 7" ATM other than the elocity a7 (was c. $300 around xmas), but it's not very hacker friendly and I don't know if they ever got the USB port to run in non-host mode... probably best to not even look at it...
The g Tablet would, as many have already said, be a great tablet if it had gps mainly and increased memory. Adding pci-e would be even better. I would be extremely happy with the addition of gps. I would be very tempted to allow somebody with expertise and high level of confidence of success to experiment on my tablet.
GPS+
Just bought my Gtab yesterday. As you know the stock Roman/UI sucks big time. I installed Clockwork followed by CyanogenMod 7 and what a difference. Anyway I looked on the web for a dock and it seems there is a Chinese version of the Gtab that has higher spec's including GPS. It would seem logical to assume the U.S. motherboard has the same circuits built in. Who knows what's possible....
It's too bad that more people don't feel like tearing up their electronics to start soldering things to them.
Padfone
Xoom
both are pluggin into what are to all sense and purposes dumber than dumb terminals.
I'm thinkng that smart phones (with security enhancements such as biometrics etc) with become ID, processor modules.
In theory I can see a smart phone with a seriously underclocked 6 cored cpu in it with core user data and mega encrypted ID capabilites.
Screens (gfx HD ram units) could now have a docking function that allows you to plug your device in providing the extra power and cooling (thats the interesting bit) to then allow you to have a fucntioning desktop.
THe corporate world will love it (hotdesking the next generation) and provide the market need to begin with.
TV's then start shipping with docking stations, slate devices.
I know the cloud is meant to help with this sort of thing but with out a decent global wobile data netwrok that really is falling flat on its 4rse.
So I got all geeky about somehow allowing a docking socket to introduce extra cooling into a CPU housed in a smart phone. (peltier tab, but how to deal with condensation?)
any way, its and idea I thought I'd throw out to the world ofXDA to play with.
ahn... what?
basically an universal ID card and a beefy processor combined into a smart phone shell that I can imagine being the norm in the new future
I can see this maybe happening for some execs and sales types. But anyone that doesn't need to have a company provided phone on them (and isn't getting one) will still have a regular PC to complete their work on.
Just had a thought, the idea falls down hard hard if you want to make or receive a personal call whilst 'jacked' in.
I still think the idea is sound though. ID card and settings stored on a portable CPU.
Hello there,
in september 2012 I bought my first tablet, a LC-Power MIRA-1. Shortly after, on the 19th I posted a [Q] post here because I had a few questions. In the following weeks, some replies back and forth, more quirks came to light.
In short, I was semi-happy with the MIRA-1 (everything was fine save a few situations where the single-core tablet speed could not really keep up, for example, starting firefox and the keyboard, it always froze 2-3 secs "firefox is not responding. close/wait?")
Still, I do believe, I learned some valuable lessons about android and others with the MIRA-1 or thinking about getting one were helped too.
Fade in today.
I recently bought the new LC-Power SINA-1. It cost me 200EUR (Germany). In comparison, the MIRA-2 (which is like the MIRA-1 with an extra camera and a smaller rechargeable battery) still costs 160 EUR
I found the new SINA-1 to be a very interesting product, especially considering the price.
I came here to write my own review. I am in no way affiliated with LC-Power and I do not get a dime for writing this.
My motive for writing this and yes, maybe even advertise, is very simple. First of all, xda-developer has helped me before and I'd like to give back. More importantly however, I believe in tablets that do not cost an arm and an leg as well as the android (modding) community. I would very much love to see the LC-Power tablets get the attention they deserve...
Thank you for keeping with me so far. Let us begin!
Technical specs for the new SINA-1 tablet:
CPU: ARM Cortex A9 Dual Core 1,5GHz
GPU: Mali 400 QuadCore 250MHz
RAM: 1GB DDR3
Memory: System 1GB + 16GB NAND Flash (+ MicroSD up to 32GB)
Display: 10.1" IPS 5 Point Touchscreen, 1280x800
Networking: 802.11 b/g/n, Bluetooth 4.0
Cameras: 0.3MP front, 2MP back
Connectors: micro-HDMI out, micro-USB host, micro-USB connector, 3.5mm headphones jack
OS: Android 4.1
Want to know more? google it
As I mentioned before, the tablet costs 200 EUR (Onlineshop, Germany, Dec, 15th 2012)
Material and built quality:
The first impression is very good. The tablet feels solid, has a certain weight to it, but is not too heavy.
The front appears to be glas and if it is not, it must be a very hard plastic. The back is made out of aluminium. I have no doubt that both can be scratched, please forgive me for not doing the experimentation on that. However, in a few days of extensive (time) yet normal (application) use, I have yet to see any marks besides fingerprints.
Where the front and back meet I can not feel any sharp edge (MIRA-1 I could).
It is very thin (quite a bit thinner than the MIRA tablet and a bit higher as well)
Overall, I would give the material and quality very good marks. I dont doubt that it could be better in some regard, even if I can't name one right now.
Display (visual):
The 1280x800 resolution suits the tablet well. It is definately a neccesary step up from 1024x768 (MIRA). Even if I did not exactly see pixalation with the old ones, the picture is indeed better with the higher resolution. Webpages like reddit look sharp, the text in 100% zoom is not too small. Pictures look vivid and good. Videos are even better (given the source material is of sufficient resolution itself).
The viewing angles are what you would expect from an IPS panel. Frontal (no angle) is best, the more you move to the side and increase the angle, the more you lose contrast and brightness. I have seen worse and have yet to observe the "picture went negative", but viewing some content with 2-3 people should not be a problem when you dont mind sticking your heads together
The brightness (350cd/m²) is good, in fact, in a dark room you may want to lower it a bit. Even on the lowest setting it is not too dark.
The contrast is equally good, or should I say "normal". It did not attract attention, neither positive nor negative...
First tests with a bright (300W) lightsource led me to believe that the glossy display does not become a shaving mirror when you have a bright light behind you, but it is definately harder to see the picture. Especially noticeable with movies.
Due to it being winter without sun, I can not test the tablet with summer-sun-brightness outside. I fear the results will not be too good. You may want to keep that in mind if you live in africa and will be using the tablet in the sun - might be trouble. (Then again, I don't know any tablet that has a matte display)
The illumination (is that the right word?) - the background light source illuminating the display with the same brightness consistenly - is adequate. There are a few bright spots (tested with a black fullscreen per 1.0 eyeball), especially on the lower left corner/border).
It is not noticeable when looking at brightly coloured images, but it will be a nuisance when watching a movie which is very dark.
I felt that here, my old MIRA-1 did do better. There, I never noticed bright spots like this before.
Display (touch):
The 5-point-capacitive display does very well in accepting touches, even light ones. 2-point touch (zoom) works equally great and the short test with fruit ninja confirmes that 5 points can be tracked. I did not experience any noticeable lag with 1,2 or 5 points in normal operation.
If you take a paint app and draw with your finger, a slight lag can be observed, however, as I understand current technology, this is common and just the way it is.
In conclusion, the display visually is adequate. Are there better displays out there? Yes, definately. Do you get them for 200 EUR? Definately not! Do you need a better display? Well, I can not answer that for you. In my opinion, the illumination is the only real and still overlookable drawback, everything else is fine. 8/10
The touchscreen part of the display is as it should be. I can not really imagine some way to improve it. 10/10
Together 9/10
Actual Performance:
The performance is quite good and right were it should be. There are faster tablets and phones out there and if we were talking about speed in my workstation or gaming rig, I would be right there with the "FASTER!!!!"-crowd. But since I don't plan on playing skyrim or bf3, rendering 3d images or encoding hd-videos on the tablet, I dont need huge speed reserves, I want a tablet that performs well with the usual tasks like webpage browsing, playing media files and so on.
As mentioned before, this is one of the main problems I had with the old MIRA tablet. 2-3sec freezes, applications (mainly the browser) that did not react and had to be waited for. With the SINA-1 they are gone. The OS works like a charm, switching applications goes instantly, browsing webpages is fun and the waiting in the browser now is for the reason it should be - networking speed! (browsing with firefox+adblock+hackers keyboard)
Since the old MIRA did perform well with movies and the games that I tested, it is no wonder that the SINA-1 does perform equally good. HD videos work well, jumping around in them works fast, even over HDMI with 1920x1080.
And I have yet to find a game that does not run perfectly on the SINA-1. I have tested the occasional gamer games like Angry Birds, some RPGs and even some 3D shooters.
It is hard to give points for the performance. On the one hand, I am fully satisfied (10/10), on the other hand are tablets and phones being sold with much much more power, at least on paper.
Button/Connector placement:
There are only two buttons, power and volume up/down. Both are placed on the right higher side, where I would have placed them myself. They feel high-quality (they dont dangle/wiggle) and have a distinct pressure point that needs some force. This helps you in knowing when you actually pressed the button and not press buttons by accident.
The connectors are on top (right side). One exception would be the headphone jack which is on the right side above the buttons.
The USB host (where you can plug in normal usb devices) is no longer a common USB port (like MIRA had), but a micro-USB. A short adapter cable came with the tablet.
The normal USB host (where you connect your tablet with the pc to access the memory/sdcard from the pc) is also micro-USB. A longer cable came with the tablet.
I would have liked the normal USB port to stay.
Also, these two distinct different USB ports look the same. Some attention must be payed to not confuse them.
HDMI is mini-HDMI. Adapter did NOT come with the tablet. (Which would have been nice!)
Power In is 5V at 2.5A. Adapter came with the tablet (duh!) - the cable is a bit short for my taste. About the same as with the MIRA before.
Note: the tablets rechargeable battery can no longer be loaded over USB
The connectors are close together, but not too close. you should be able to connect all 3/4 with power at the same time.
The microSD slot is on the right side, almost on the back.
Speaker: The speaker(s?) is on the backside. I feel like the device is not as loud as the MIRA tablets, but still works well for watching movies or listening to music in a normal room when you are alone.
Software:
Android 4.1 is working great.
Some might argue there are a few needless apps preinstalled. For example Google Maps and Navigation on a device which has no GPS and no mobile internet built in.
But there is no real crapware either.
Google Play:
Google Play is installed and working fine. The device gets shown as "Rockchip SINA-1"
I did run into some trouble with my old MIRA-1 and some apps. A few were apparently not compatible (although I did not understand why), others that were compatible did refuse to install (I can not and will not exclude a layer 8 problem here)
All those apps work now with the SINA-1. Install is fast and there is no trouble. The 16GB memory will suffice for a lot of apps.
Battery:
The rechargeable battery is a bit less powerfull than the one in the MIRA-1 and a bit more powerfull than the one in the MIRA-2.
Still, with the higher speed and I would assume, higher resolution, more power is needed. Hence with usage, the charging level does indeed go down. Quite a bit faster than with the MIRA-1. I will have to correct my earlier estimate from 5-6hrs down to 4-5hrs.
In fact, bring your loader if you are gonna go out all day and will be using the tablet much.
Support:
LC-Power is usually quick in answering normal support emails, but they will not exactly fall over each other trying to resolve any exotic issue that might come up. Maybe if you speak mandarin and mail them directly at tech and dev headquarters in probably china you might have some luck, but I doubt that the LC-Power people in Germany, USA or UK or ... had much to say about developing the device and customizing the android (except of course, maybe some translation)
Also, do not expect regular android updates or any long time support and new android versions. 2-3 months ago I was promised 4.1 for the MIRA-1, still hasn't been released.
Connectivety:
Wireless LAN b/g/n is working as intended. I feel however, that the signal strength is weaker than with the MIRA-1 tablet.
Bluetooth: What can I say. Its Bluetooth. Its there, it can be used, it works...
Mobile internet: Only per additional USB dongle (or tether your mobile phone...)
Ethernet: Apparently there are USB dongles for Ethernet LAN out there. Havent seen one yet, but I havent looked hard either.
Modding:
So far, there has yet to establish a big LC-Power community with modders, mods and custom roms. I really really hope it will happen some time. But dont hold your breath, you are on your own. Spread the word of the LC-Power devices, lets get a high enough market share an the chances of a active modding community will rise dramatically. Or do it yourself...
So...
if you dont care about mods and custom roms, the SINA-1 is ok for you.
If you want to play around, learn android, program aps, make mods, maybe even a custom rom, feel free to give the SINA-1 a try.
If you want to download the newest custom ROM, install it per 10 step manual and prag in school about your mad hacking and modding skills, look someplace else...
Rooting:
The device does not come pre-rooted. (MIRA did)
I welcome that change to some degree. I honestly believe in not giving the run-of-the-mill users the ability to break something beyond their own (or even some specialist) capability to repair it.
Then again, I also am not fond of the tricks one has to employ to actually root a device IF someone knows what he is doing and wants to use a device to its full potential.
That being said, it was relatively easy to root the SINA-1. Instructions at the end of my review
One last sentence about the stock ROM. It is not available for download (at least I could not find it). I know of no way to reflash it or recover a bricked device. You wont find extensive help, manuals and tipps to that end. Make sure to have an appropriate backup and/or tread carefully.
I myself will investigate, if you have any insight into that topic, feel free to contact me...
Summary/Conclusion
I really like this tablet. A lot. I found it superior to the MIRA-1 in almost all aspects (especially speed, compatability, screen resolution and build quality). It has however its week points (battery run time, uneven lightning of the display).
Since it is a 10" tablet without mobile internet, it obviously was made for home usage. Browsing webpages from the couch, watching a movie while your in a room without a TV, or listening to music without bringing your stereo, add a game now and then when you are bored. This is where this tablet shines. I could imagine it being used in a work environment / office as well. And when the batterie gets low, you hook it up.
The occasional traveler should be happy as well. Get a dongle or tether it to your phone and you can surf the web in the bus/train. Hook up your headphones and watch a movie (just hope the sun doesnt shine too much). Also, dont expect the tablet to last a flight around the world without loading up...
All in all, a very decent device with a very attractive price.
So should you get it? Well, it depends...
If you have a MIRA-1 or 2 and you are really happy with them, you dont care about waiting 1-2sec for some apps. Then dont get the SINA-1
If you have ANY other single core tablet that is not up to its tasks, makes you wait for apps, annoys you in some way, yes, give the SINA-1 a try - and sell the old one for some cash...
If you are thinking about getting the MIRA-1 or 2 (or another similar single-core device), try really hard to look for the other 40 EUR and get the SINA-1. Or get the MIRA used for like half its retail (~80 EUR), but be warned about the possibility of the tablet being to slow now and then
If you have another dual-core (or more) high-end tablet, probably with a big name on it like some fruit or samsung or nexus.. Sure, buy it. whats another 200 EUR. Or dont, I dont think it will be an upgrade. Just another tablet, even if it is a decent one
the get it or dont get it reasons in the modding subsection still apply
I myself regret nothing. I watch movies in bed, I surf the web on the couch. If I am really lazy I even open up teamviewer to do 2-3 clicks on my PC without getting up. I take the tablet with me on train rides and watch a movie or surf the web with my phone tethered. And I recently started to use it at work for presentations (put my notes on it). And when I am bored, I do play a game now and then.
Mind you, I did/could have done all that with the old tablet as well. But it sure makes more fun now
End of the review---
I certainly hope that this rewritten and formated review is more informative and better on the eyes.
I think I got most of my english mistakes as well.
I hope this helps some folk decide
If you have questions, feel free to ask them here. I will try to look back now and then and answer those questions.
good day

Addendum:
How to root the SINA-1
Disclaimer: no guarantee, you break it, not my fault bla bla...
First, it was not difficult. It was done by the "root with restore by bin4ry method"
step 1: enable usb-debugging and allow installing of "foreign apk's" (or whats it called in english)
step 2: get a usb driver for windows (7 x64 in my case)
step 2b: since you probably wont find a driver, modify the google drivers from the android development sdk. add the line to the google.ntx86 and ntamd64 block:
%CompositeAdbInterface% = USB_Install, USB\VID_2207&PID_0010&MI_01
Click to expand...
Click to collapse
step 3: add the file adb_usb.ini at /users/[username]/.android directory with the following line:
0x2207
Click to expand...
Click to collapse
(i had to do this in my user account and in the administrator account*)
step 4: connect the tablet with your pc, make sure all drivers were installed and usb debugging is on
step 5: google, find and download the zip archive with the batch file, scripts and tools needed
(root_with_restore_by_bin4ry_v17.zip did it for me)
step 6: extract the archive, best to some easily found directory like c:\rootit
step 7: start a command line (cmd.exe) (as administrator?)
note: the actual rooting only worked for me when i started the command line as administrator
step 8: start runme.bat from c:\rootit, ch
step 9: choose method 1, wait for it to finish
(all this information was googled and very little trial and error. did not take me more than 30mins with no clue before hand whatsover)
Drivers
can you please explain how did you installed drivers?
I'm having troubles following your manual. I need sina-1 for developing but i can't connect it with adb cause drivers aren't installed correctly.
tnx for review.. I bought SINA-2 and use your method of rooting and it works.. have U tried some custom rom already? I don't know which is compatible with my device...
Does anybody know how to flash recovery or custom rom to this tablet. I have googled and nothing found. Maybe there is no recovery or custom rom for this device.
Update 9 months later
very small update after a few months of light and sporatic use:
- rechargeable batterie runtime:
I might have overestimated the runtime originally. additionally, rechargeable batteries dont get better over time...
that means that you really will be running to the charger a lot at home and should take it with you.
do not expect to be able to surf the web or watch movies the whole day without recharging.
- wireless range:
the wireless range is really really bad.
I originally stated it to be not great, but actually it is really bad.
No other device I ever had or currently have had a worse range.
expect slow transfer speeds even when directly next to the router
expect trouble even behind one wall / more than 5m away
expect no connection or unuseable for anything expect the most rudimentary stuff (getting an email) behind more then 1 wall and/or more than 5m away
--> apparently this WAS a problem with the earlier SINA-1 tablets and LC-Power will fix it. This would also mean that the newer ones should not have this problem
--> this bad wireless connection might also be a reason for the bad batterie runtime
- micro-sd:
I've had bad trouble with my 32GB MicroSD card(s) (SANDISK 32GB SDHC microSD Class 10)
the previous tablet (mira-1) took it, my even older mobile took it, the SINA-1 did not...
since my 8GB and 16GB cards were working I thought my 32gb card is incompatibel
--> A few weeks ago I could test another SINA-1 (new), no trouble with my 32gb microsd...
- Android
no new android / update has been released by LC-Power (that I can find)
- Modding:
still no real community
- Apps / Games
a few games (that might need a somewhat more powerfull device) that I can tell you are working are:
magicka, pokerstars, terraria
- built, glas, buttons
after light and cautious use over many months, the tablet can still look like new (if you clean it)
I have no scratches, no color scraping off, the buttons dont wobble. its like new
- the power-in jack
this needs a mention too, since it really is not well done. the plug fits, but will fall out very very easily.
best not to move the tablet when you have it plugged in
conclusion:
my first review still stands more or less... for its price this is a okay tablet
if the wlan is indeed being fixed and the batterie will run a bit longer for the current sold devices, this is still a good buy for ~150 EUR
since I do not really know what is wrong with the microsd issue (my tablet broken? newer tablets unaffected) I can not use it for reviewing. but be warned
HOWEVER...
there is a new LC-Power SINA-2 tablet that I will be reviewing soon...
I will post the link later
Thank you so much for sharing.
Very useful review, thank you.

Front camera not supporting video calls
Hi!
I was wondering if anyone who owns this tab had any issues with incoming/outgoing video calls (via skype/facebook/ooVoo).
Fact is, I can't make video calls via any of the above software, when i try, skype just blanks out and goes to previous screen. When incoming calls arrive it does the same but it says that I have a missed call.
OoVoo on the other hand connects to video call but automatically uses the back camera instead of front.
I don't get it. Any advices/ideas?
Thx
Here you go guys This tablet got CM10.2 fully working, with stock kernel <3

And Sina 2 review?
Why do mobile companies restrict the use of SIM cards from phones from being used in tablets?
While phones were mostly less powerful than the new tablet devices and the larger screens meant there was a greater data demand by tablet devices, this is certainly no longer the case.
Phones are now more powerful than most tablets and the rest are simply equal. Processors are quad core clocked at similar speeds, if not not higher speeds, the working memory is again the latest 1-2Gb configuration with 16-32GB internal NAND flash memory. With phones having the latest 128GB external SDXC memory support to compliment the superior camera resolutions of 22 Mega pixels. Cloud services are now just beginning to gear thewmselves up to cope with this data interchange whereas tablets still have only modest cameras. Phones do now have front and back facing cameras and the similarities continue to converge.
But crucially the screen resolution has become irrelavent because of technical innovation and it is commonsense the data is sent highly compressed through the Internet where it is decompressed and interpolated to match the local screen resolution by the local graphics processing unit, GPU. This item is again of superior design, as a matched technology to the central processing unit, CPU where the mobile phone market is concerned. Both CPU and GPU are expected to have multiple cores to improve performance and the designs are optimised to consume as little power as possible. A great advantage for a mobile phone. The competition leads to great performance in wider world applications and this is the reason for the extreme competition that has been encouraged in the mobile phone marketplace. But of course we, the public, are paying for this R&D whereas it used to be hideously expensive top secret military R&D budgets. The senate was worried about the cost of a hammer and a handfull of screws at one stage.
There has been a complete change in the definition of mobile phone and tablet where the OS is now exactly the same for each, being Android 4.x.x.
So why are telcos forcing people to purchase a separate SIM for each device? I am disabled. I need specialist communication software to assist me in communicating when I am travelling. For this the tablet is better. But while at home or when meeting friends during the evening the mobile phone is the better option. But the telcos refuse to let me use the same SIM in both devices. I cannot use both devices at the same time so I don't see the logic behind this situation.
The situation continues because the telcos think we cannot see they are continuing to enforce this barrier so that they can make a greater profit from users. Please help get people to recognise the false pretence that prevents us all from exercising a freedon of choice to use either device according to our intended purpose without the need to purchase separate SIMS. Afterall, because I can only use one device at a time why am I forced to pay for two 3G or 4G contracts with separate data components?
I don't see any common sense in this situation and I do think we are all being ripped off by this legacy programmed system restriction.
And I did install the phone SIM in my tablet after being told by the telco staff it was OK, where it worked happily for approx 12 hours. Later when I enquired how I could set up the voicemail and SMS services an arrogant technician then told me I could not install this SIM into a tablet, followed rather weakly by, it will stop working after a time.
Given the conflicting statements and the fact the SIM was working when I was being told it would not work I question the reality of the reason for it not working. It may be recognised by a systematic ID check. But the blocking of the data services after an arbitrary period of time raises the question, "Why shouldn't a SIM now work regardless of whether it is a Phone SIMor a tablet SIM.
The legacy rationale a history of tablets as they were originally a platform for advanced circuitry and software to be released and the resulting extra data demand to their internet connection lasted only as long as the phone market had not become so competitive that their technical facilities raced ahead of tablets. In fact the technological improvements in hardware and saftware have brought both devices to an equal status where users can choose the device according to the context of their intended purpose.. So much so that having more than one device to suit practical applications in varied social settings with no impact on the data portion of their respective uses. Example, you can now watch films or TV series while commuting.. Preferable to use a smartphone here. But you can continue exactly where you left off on a tablet or even a smart TV! The data compression and local pixel mapping to suit the resolution of the device is done locally and absolutely without any impact upon the data demand or stream.
There is no reasonable argument to continue differentiating between Phones and Tablets other than to enforce an obsolete regimen and to unfairly extract money from phone and tablet users who unwittingly pay twice for the same telephone and data services! Copyright(CC) Arclite 13-03-2015
I swap my SIM between my phone and my tablet several times a day. Never had a problem with it...
