[Q] Android Tablet: Gpu/display resolution mismatch? - General Questions and Answers

Hi to everyone: I'm a newbie on this forum and in general with android platform.
I've recently installed a few benchmarking apps on a Trekstor xiron 10.1 tablet ( target data : 4cores 1.6 Ghz, 2gb ram 1200x800 IPS))
I obtained contradictory device info:
antutu: cpu =rk3188; display 1200x800
quadrant: cpu=armv7 4cores rk30board; display=1280x752
cpu-z: cpu rk3066 rev. r3p0 4 cores; displa=1280x752
Because I don't want to disassemble the tablet to solve the mistery, I decided to test at least the display to see if I was able to argue some more infos. On the lagom dutch website I found a full set of pages to test LCD display.
I tested both the Treskstor tablet and an older Mediacom 101s2, a sort of rebranded Sanei N 10 (rk3066, 1gb ram, 1200x800 IPS).
Apart a reasonable difference in brightness, contrast and colour setting, I discoverd the trekstor tablet shows a moire' pattern in a dedicated test image (lagom.nl/lcd-test/clock_phase.php) and this is a symptom of the graphic adapter setting doesn't match the native display resolution. In the same tests the Mediacom display works correctly.
In the normal use, comparing the two displays, the mediacon one seems "crisper".
So my question is: is it possible such a kind of mismatch between the gpu resolution and the display resolution? Can I solve it in some way?
Thank you in advance

Sunno s880 3 kinds, Opinions please!

Hi, Im very interested in one of these sunno phones, there are 3 models, 1 of them is a cheap copy that I wont buy. The other ones are originals from sunno factory, witch one would you choose? please let me know why
There are 3 kind of s880, (please tell us about them if you have any of them)
The great one:
CPU: Marvell PXA310(1GHZ)
Look at the back camera(thats the diference)
Main 5mpx cam,
No android os
Just wm6.5
Where to buy?: www china-mobile-phone com
PICS:
N/A I have links restriction
The second most powerfull:
CPU: Unknown 806MHZ processor 256RAM
Diferent back camera, 8mpx

WM6.5 and Android
Where to buy?: This one seems to be a cheap copy, so be aware. If you find that back camera in a s880, thats a cheap copy.
PICS: N/A I have links restriction
I will add photos to this post when my links restriction is gone
Please, give me your opinion about witch one should I buy, and why
thanks!
Hi Mhz250,
I've been delivered the model you describe as "The Great One", i.e. with 1GHz processor (at least, that's what it reports) and NOT dual boot.
I can't tell you which one to buy as I'm not familiar with the others, but below are some of my impressions. As a disclaimer, the model I'd ordered was meant to be the dual boot one, so I'm a bit disgruntled, and also this is my first smart phone, so I don't have anything to compare it to with regards performance. However I do have an Ipod touch so I'm familiar with capacitive screens.
Build Quality:
The body feels reasonably solid. There's a bit of a plastic squeek when you squeeze if from the sides but otherwise there's a nice weight to it. The battery cover is metal and again feels solid.
The buttons below the screen and the two volume buttons on the side feel robust, but the cover for the memory card slot is a loose friction fit, and the small power button feels like it might eventually fall out.
Screen quality:
Brightness:
It doesn't seem as bright as my Ipod touch, even with the lightness up full. I've not tried to use it outdoors on a sunny day (I'm avoiding using it until I've my support query on sorting the dual-os settled) but for indoor use it has been fine.
Touch:
I'm using a screen protector that I ordered with the phone, which might have an effect on the responsiveness. It is a resistive screen rather than capacitive: sometimes a light touch is sufficient to get a response, other times you've got to press firmly. I'd characterise the difference like this:
- with a capacitive screen you can lightly "swoosh" with the pad of a finger to scroll
- with the S880, I find I either have to drag with the pad of my finger to scroll, or else use the tip of my finger/nail.
- in general, I find I've to re-enter my taps etc to get a response some of the time, other times it works fine.
- also bear in mind that you will not have multi-touch (pinch-to-zoom), which makes browsing less convenient.
OS:
In my opinion Windows mobile 6.5 is not very nice to use without a stylus: the settings menus and the keyboard are rather small and, although not impossible to use with the tip of your finger, it's still quite easy to select the wrong item. Note that the S880 doesn't come with one of those built-in stylus slots (or even a stylus). Installing FingerKeyboard helps with the keyboard issue, but doesn't help with the small menus.
The lack of an "alt-tab" built in to the OS to switch between running apps is a pain. Perhaps due to my unfamiliarity with the OS, I keep finding myself back at the home screen and have to re-navigate to the application (sometimes via task manager).
I downloaded a trial of SPB Mobile shell and that helps to make the screen feel more responsive. That's all very well while you're in the SPB shell (navigation) but when you finally arrive at the app, you're back in the Win6.5 world . It also adds an extra $30 to the factor into the cost, but if I cannot get the dual-os issue resolved, I'd personally go for this (and, before anyone asks, no, I'm not affiliated with SPB)
So, although this shouldn't be a review of the OS, in terms of selecting which S880 model to go for, all else being equal I'd lean towards the dual boot in order to be able to use Android. (I'm sure there are threads arguing over which OS is better, I don't mean to kick of any such debate here).
Conclusions
This is an admittedly selective review: for me, the two dominant factors are the resistive screen and the Windows interface, neither of which I particularly like, and I don't think they compliment each other.
I hope this helps!
Hi itburns!
thanks very much for such a great personal opinion! Could you test the camera for me? I really would like to know if it can take pictures at night, what's the pictures quality, real MPX of the camera.
Could you also please tell us your opinion about the speed of the phone? try to use a couple of apps at the same time and see what happends. Or a 3d game if you can!
Thanks again
Thanks for a good review! Its always nice to get personal feedback on Chinese cloned phones!
>Could you test the camera for me? I really would like to know if it can take pictures at night, what's the pictures quality, real MPX of the camera.
The camera has a popup controls dialog with the following settings
- Resolution: L, 1M, 2M, 3M
- White Balance: Auto, night, daylight, {some bizarre symbol that might mean fluorescent light}, incandescent light (a traditional lightbulb)
- EV: +/- 2 stops
- Location for storage;
- Wide-screen review
- Auto-timer
There's also a quick route to view stored pictures and a menu: the menu has
- Special Effect ( a bunch like b&w, sepia, etc)
- Snap sound
- Flash
- Iamge[sic] Quality : High Low Normal
- About: Camera V1.0
I took just a couple of shots outside at twilight and at night. Twilight ones appeared on the screen pretty close to what I was seeing. Not entirely sure what you were looking for with the night shots: they look dark, naturally! I've not viewed them on a pc yet (so no opinion on the quality) but on the phone's screen you can make out street lights etc. in the night shots
Stored as: Jpeg
Sizes: 2048 x 1246, 1600x960, 1280x768,

If I'm not mistaken, apps don't run seem to concurrently in Windows Mobile: i.e. although in RAM, they remain in a sleep mode until you switch to them. This seems to be backed up by the view in task manager: CPU usage remains 0% for "running" apps. So running other apps shouldn't really affect performance other than by hogging RAM.
I've no 3D games (and anyway, as this is my first smart phone, I'd have nothing to compare with). As an aside, the phone has Teeter installed (one of those marble-around-a-maze) which, although it doesn't show off the graphics or processing, it does show off the gravity sensor and it works really well.
I did a quick scan of xda-developers for benchmarking and came across SPB Benchmark (again, I'm not affiliated with SPB!). I'll give that a run and let you know. I don't know if there are other benchmark tests worth looking at?
Hello,
You can look at the technical characteristics of Sunno S880. This smartphone model uses Marvell PXA 310 806 MHz processor but the actual CPU frequency is 624 MHz. The CPU is fast and works well with almost all applications. It can run on Windows Mobile and Android, but for now there is not a complete ROM for Android. The camera is type CMOS sensor, 1944x2592 pixels, 5MP and its quality is not different from the other Sunno Smartphone models. It depends on the environmental light, however, there are different built-in filters that improve the image quality.
Hi infobg,
thanks for that link: the model I has some differences to the one listed:
-cosmetically, the back plate looks distinctly different, while there's a slight difference on the front.
- the device information (as reported by the device itself) states
CPU Model: Marvell PXA310
CPU Speed: 1GHz
So either this is a slightly different model to the one at the link, or the information can be/is faked in WinMob Settings/Device Info.
Could you explain a bit more "for now there is not a complete ROM for Android" - I have a complaint in with my seller because the phone doesn't support Android. Is a ROM due soon, and how could I get it?
Many thanks
Hi Itburns,
the information on the website is actual. We have added a link to the Marvell PXA310 CPU specifications. It runs well up to 624 MHz, so bear in mind that Windows may not show the right information because the equipment information is recorded by the software developer. This CPU generally supports the Android core, but there isn't yet a stable version for it.
It seems we need a benchmark of your phone itburns.
infobg, I've been researching a LOT in the web and there are actually 3 models of this phone. One of them seem to be a fake, another seem to be a old model and the other is the actual model(the one with 806Mhz CPU running at 624mhz)
It seems that the first model was the one with 1Ghz processor.
Itburns, hope we can see your benchmark test soon!
Im looking to buy your s880 model
Sunno S880 Benchmark
Description
The SPB Benchmark software runs a series of separate tests under the following headings:
- Main
- Sorage Cards
- Battery
- Active Sync
Setup:
I skipped the battery test: it involves things like brining it to full power, then allowing it to run out of power, then repeating under different conditions; hadn’t got the patience.
General: - After initiating the test, I didn’t interact with the phone until the tests had run to completion.
- Connections all off: phone, Bluetooth, wifi
- Screen “lightness” set half-way and timeout for dimming set to 15 seconds.
Specific test setup- Main, File – performed with the phone powered by the mains (but with the battery also at 100% power.)
- Active Sync – performed with the phone connected to a HP laptop.
Results:
The Spb Benchmark “visualise results” didn’t work when the combined tests {Main, Storage Card, Active Sync} were in the results file, so I split out the storage card results and uploaded {Main, Active Sync}: it is possible that this could affect some of the cumulative results? Anyway I’ve copied the relevant part of the xml file below for the storage card test.
The comparand (iPaq 3650) has a 206 MHz Intel StrongARM SA-1110 32-bit RISC Processor (source ipaqrepair.co.uk)
- The “Pocket Word” and “Internet Explorer” tests did do something, I could see stuff pop up on the screen (which came alive during the test), so it is possible that the test just failed to grab the results. IT IS POSSIBLE (PROBABLE?) that the cumulative Spb Benchmark index is incomplete or unreliable, given the few failures?
- Note: for some values it would look like a low value is good (File system index?), but the hyperlinks on the spb site to explain the benchmarks seem to be broken, so I cannot be sure.
Spb Benchmark Indices
Spb Benchmark index: 463.21 (iPAQ 3650 scored 1000)
CPU index: 2657.1 (iPAQ 3650 scored 1000)

Sunno S880 Benchmark - Second test
CORRECTION: In my first posting, I said that the S880 doesn't have a built-in stylus, but I have since found it! It is very neatly hidden in the bottom right of the phone.
Ok, I've now run SKTools' benchmark. There seems to be quite a variation in the results on different runs of the tests, so this is only a snapshot and may not indicate the best or worst performance of the S880. The SKTools results usefully provide results from other phones: in the results below, I've also given results for the Touch Diamond (528MHz), Samsung Omnia II (800MHz) and HDC Touch HD2 (1GHz). Mhz250, I took a look at the video on china mobile com and the form factor of the model matches my own.
Setup as before:
- phone plugged into mains
- connections off (bluetooth, phone, wifi)
- Screen lightness mid-way, with a timeout of 15 seconds
Results:
Integer: 347 Moves / 25usec :
Compare with: 331 HTC Touch Diamond (528MHz)
530 Samsung Ominia II (800Mhz)
813 HTC HD2 (1 GHz)

Sunno S880 Conclusions: Steer clear!
So, up to now I've been recording first impressions and also benchmarks. Now that I've had some time to use the Sunno S880 as a phone, it is worth adding: it's rubbish.
a) call quality is very poor - those calling me hear an echo of themselves and also complain that it's very hard to make out what I'm saying. So if you don't want to be continually be repeating yourself, avoid.
b) the phone continually loses signal, often mid call. And I'm not talking about areas of "poor reception", this happens in our capital city.
Additionally: battery life is very short, I was getting a drop of about 50% overnight with light usage (about two-three calls, 5 mins playing mah jong).
In the end, I had to cut my losses and buy the cheapest big-brand phone that I could live with, so I got a Samsung Tocco Lite. Although I'm no fan of its software interface, the call quality on the Tocco is crystal clear and there's none of the loss of signal that I was experiencing with the S880.
So I'd have to conclude: avoid the Sunno S880.
Sunno s880 pro
Hi everybody
I would like to give you my feed back about the Sunno S880pro.
First I bought this mobile phone to the website Mobino1, the shipping was fast.
1-My first surprise was that the package was a bulk ,not in a nice packet (like the samsung phone).
2-The phone in itself is nice , the screen also.
3-The problems comes when I wanted to use the phone.
The wireless, bluethoot and phone network are not stabile, I have always disconnections. An When a use the wireless, bluethoot the Battery discharges very quickly.
The Big Problem is that I cannot make a call and send SMS With the Mobile phone company "BASE" (in Belgium). So with friends we tested with anothers Mobile phone Company " Mobistar" & "Proximus",In this case the calling work well.
So I decided to change my subscription to Mobistar.
To my big surprise after two days the disconnection problems come back again.
I still have the problem actually.
I try in vain to find another ROM for this phone ,but I have not found.
If someone has the program, I m interested to have.
thank you for your understanding
sorry for my poor english

[Q] TechPad 7" Tablet upgrade from android 1.6 to 2.1

Hello,
I bought The TechPad 7" Tablet with android 1.6 from chinavasion.
Is it possible to upgrade to android 2.1?
If yes would it be slow?
As it is now video performance is not good!(tried almost every player)
Specs: arm11 800mhz cpu, 256MB ram, 1GB rom, (i discovered it is actually 2GB),
wi-fi ,7" 800x480 lcd screen etc.
Thank You.
me too
I believe in very others locking for this, me too. Please if anybody to find it answers us. Thanks
I had some initial success with putting Android 2.1 from JetPlatform-experimental-binary-100624-2.6.29.tar.gz or JetPlatform-0.3pre1-binary.tgz while retaining the original linux kernel 2.29 on the inbuilt 1GB card. To do that I had to open the device.
Some things were not working 100% correctly with the new android so I put back the original card. 2.1 was faster than the 1.6, but home screen was blinking from time to time.
Also my chinavasion model did not had volume buttons, so I added them from an old Lexmark printer, pictures here: slatedroid . com/index.php?topic=7344.0 (scroll to page 15).
PS>Did you notice some software upgrades on this page: download . chinavasion . com ?,
look for device code PC07, some users said the wifi update is helpful.
as for the video, use mp4 to allow for the inbuilt hardware acceleration. Follow the howto by tenzen2, can be found here: dealextreme . com/forums/Default.dx/sku.41984~threadid.730189
Yeah I had same problem with android 1.6, got from chinavasion. Its dead slow. I wonder its not possible to upgrade and if it is, i wonder if its clarity and performance will be good?. I have a new android 2.1 directly got from ChinaBuye. It has faster and clarity is excellent. So upgrading will not be effective. I find rate is also quite low here, and buffering is faster. Check with chinabuye if you decide to get new 2.1 android.

[Q] Adobe Photoshop touch

I have CM7 on my Tab. As such, I am on Gingerbread...
Any one can "hack" this so that it's made compatible with it?
Thanks in advance!
isnt it available on Market?
not compatible because :
Tablet requirements
Operating system: Android™ 3.1 or higher
Display size: 8.9-inch or larger
Display resolution: 1280 x 800 minimum
Camera: Recommended
source : http://www.adobe.com/products/photoshop-touch/tech-specs.html
It is available in the market but for Honeycomb only...
I know it's not supposed to be compatible (I read the requirements) but my question was wether it would be possible to adapt it...
and i thought you meant Photoshop Express! sorry my bad!

[Q] Drivers for un-branded Tablet

Hi there friends,
I recently bought a cheap tablet that I suppose came from China.
I cannot post a link to the device but if one were to google "trademe" ( a new zealand auction site ) and in the search box type " 459557872 " it would link to the sale page.
In the system info the only description is model; A710
Specs as follows;
-Main IC: High performance 1.3GHz Allwinner Tech BOXCHIP A10 Cortex-A8 CPU.
-Screen 7 inches 16:9, 800 * 480 ,Capactitive five point touch screen
-Memory DDR3 512M
-Flash 8G capacity
-Storage Extend 4GB-32GB SD/TF -Support
-WiFi 802.11b/g/n
-Front Camera 1.3M
-G-Sensor All gravity induction
-OS Android 2.3.4
- 7" high sensitive 5-point capacitive touch screen.
-Battery 3000mAH
Currently running Android 2.3.4, but i would like to put ICS on it somehow, but this is for another day.
I would like to root this device so i can use a proxy at my school but Windows cannot find a driver for it and therefore Superoneclick does nothing but stop responding.
There is no branding anywhere on the tablet or the box it came in.
Where would i find the necessary driver for this device?
Thanks in advance,
Corbin
