Galaxy S2

Hey everyone.
I ran across this over at the GS2 forum.
This guy has one.
Check out his blog

Some pretty impressive numbers there, and a very complete selection of benchmarks.
Would seem like the CPU in the GS2 is at least 2x more powerful than the Hummingbird in ours. Also some impressive GPU numbers.
Thing is though... the original Galaxy S was like 6-8 months ahead of the curve in pretty much every facet of the device. Even now, no other device on the market can compare with the Super AMOLED screen. The Galaxy S2 however has some impressive specs, and a very cool looking (and very thin) package, but it doesn't feel like it's going to be the "step above the rest" that the original was.
Guess we'll see when it's actually released!

Not that it matters, but that's got to be some of the highest quadrants ever recorded.

That looks very promising. I could upgrade my cappy to that for sure. To date i have not seen anything worth upgrading to...

I wish it was a 4" screen. Wouldn't want a 4.3" one with that resolution (personally). Because I'm on a two year contract I'm hoping the Galaxy S3 is leaps and bounds above the S in display and processor technology... and comes in a 4" variant for battery savings.
It still looks cool though

I'm really on the fence about it due to the screen size (for battery life, size of the handset) and the resolution. I may be able to live with the lack of resolution, but I'd have to see battery life numbers before I even think about swapping out my captivate.

Just got mine today very impressive and fast. Very responsive and thin.
Camera is brilliant and video recording wow best out there.

I was really looking forward to the galaxy s 2 but I am thinking its gonna be awhile before it is released. I find it hard to believe with the infuse on the way (but to the best of my knowledge also with out a release date) that samsung would cut their own throat by following the infuse with the galaxy s 2. I have been eligible for an update for awhile so I am thinking there is going to be allot of competition when it finally arrives. IMO samsung has really dropped the ball by not releasing here sooner, especially if it has to face the iphone 5. At this point it seems like the sgs 2 will be doa as the next killer phone if released in the fall.

that score in antutu is quite impressive! holy crap that's fast tegra 2's need to run at 1500 mhz to beat that!. the 3d benchmarks are likely heavily held back by a cap on the fps just like the captivate is already. i have gotten 491 points for 3d alone in antutu with a certain kernel and rom combo and that wasnt even with the gpu overclocked or fps cap removed like some of the vibrant kernels and old captivate 2.1 kernels. could do.
i want to see that thing run without any fps caps and some kernel tweaks! no overclocking.

I might upgrade next year. I think it's a good to give 6 months to a year before getting a top of the line handset.
That's enough for bugs to be noticed (and hopefully fixed), for community development to take off and for the apps to catch up with the new phone's technology. Correct me if I'm wrong, but right now the only apps that can take full advantage of the Sgs2 processors are benchmarks.

For those interested, Engadget UK just posted a review of the Galaxy S 2:
http://www.engadget.com/2011/04/28/samsung-galaxy-s-ii-review/

SO gps works...
BRB preordering

Glad they put the USB at the bottom

yeah but is it using the same type of internal memory? that is the biggest bottleneck of any device or computer is the *hard drive*
the internal memory in current phones is single channel read OR write crap.
and please dont say ddr2 memory.... thats different and only helps a little in comparison to the issue with the storage memory

I think I'll just wait for what samsung promise to have a 2ghz dualcore nxtyr or later, I'm still in my 2yr contact though

i like the coment at the end "best smart phone period!" says it all!
that said i am a little disapointed with the 3d performance of the dual core phones. though the tegra is a powerful application processor and the orion is fast beyond description the open gl performance isnt much beyond what the galaxys already does. was samsung just that far ahead in that area or is there power to be unlocked in these chipsets?

Why on earth would u want to upgrade to Galasy S2?
They have so much potential and best tech in screens, internal storage, cameras, processors, and good design builds in past YET lately they rush everything (unfinished drivers, bad gps, same 16GB internal but they could have 64 and average camera and cheap plastic to save on costs) so that they can copy iphone because they want some of their success. i personally hate iphone, but every other company copying them just drives apple to think they r the best.. and personally they did make the right choice on A5 to use powerVR543 because even dual VR 543 is faster than quad-core mali400, (big mistake for Samsung as mali400 alone is almost twice weaker than PowerVR 540 used in previous galaxy, which confirms in benchmarks) and NO 3D in galaxy S2 which puts LG optimus 3d and HTC evo 3D in front. and 3D is the future with more and more 3d movies out. and same wvga res that has been since winmo 6.0. sure u don't need the very highest res in a phone, but when u connect it to HDTV via hdmi u will have to rethink that, but then again does galaxy s2 even have HDMI?? On this site: http://www.samsung.com/global/microsite/galaxys2/html/specification.htmldoesn't doesn't list hdmi or anything...
Here where things become worse building a phone with large surface area due to 4.27inch screen and full plastic yet copy iphone in trying to make as slim as possible makes it extremely breakable as the phone will slowly start bending over months as u keep it in ur pocket tightly while playing sports etc. This used to happen with motorola razer
And to top this off Android 2.3 DOES NOT fully support multiple cores, well it supports but doesn't take advantage till 3.0 honeycomb (or 3.1 for phones), so if samsung doesn't give u an update AGAIN, or rushes it out full of bugs like they did for galaxy s, ur phone will never see it's potential
And i also got a bit of info from a tweeter a few month back where it was said that samsung is working on quad-core processor for next year and chances are the next one will also be 3D. This goes well in line with guad-core Tegra 3 to be out this fall, and sony NGP already running quad-core.
Point is unlike galaxy S which had at least the best GPU on the market, Galaxy S2 doesn't have anything that stands out. Sure u have super amoled plus, but others will have higher res, and dual-core is MAINSTREAM now. And it will only be a matter of month before this phone be obliterated by it's succesor.
Also from the lawsuit that apple has recently put on samsung might force them to restart making innovative designs like they did prior "galaxy"

You're wrong in several different ways.
1- There's very little point in putting 64gb of storage on a phone. 16/32 internal + 16/32 sd card is way more than enough for me and for 99.9% of users;
2- Reviews of the sgs2 camera place it as one of the best in the market, not sure I'd call it average;
3- Apple's lawsuit is bs and I honestly doubt it will affect anything on the long run. Android and touch wiz are quite different from Ios in important ways;
4- Why do you need 3d on a phone? Where are the apps for it? Why would you watch a 3d movie on a 4.3 inch screen? It'd probably kill the battery before it was over. Maybe, it'll eventually offer some real world advantage, but right now it's just a gimmick;
5- The Sgs2 supports hdmi out via micro usb through mhl technology. Google it;
6- It's wrong to question the build quality and durability without having ever seen the phone upclose. So far, I've seen nothing but praise on reviews and previews. Plastic not only keeps costs down, it also lowers the weight. And since when is making a phone slim apple's idea?;
7- I don't have the expertise to comment on the cpu and gpu, but the benchmarks seemed impressive as hell to me;
8- Screen resolution could be higher, but super amoled technology is so far ahead of the curve that I bet it will more than make up for it.
In short, why upgrade to sgs 2? Best cpu on the market (according to engadget review), best screen on the market, one of the best cameras on the market, bt 3.0+hs, microusb hdmi out, usb on the go (according to gsm arena) and the fact that the galaxy s is already a great phone.
Obviously, there'll be a better phone, eventually, that's the way it is in the tech world, but right now it seems to be a fantastic device, as engadget review shows.

I dont care the phone is sick and I can't wait to get one. I love my sammy captivate and knowing that's the same thing all jacked up is great. 3d is dumb especially on a phone. Plenty of storage. It will be great to finally have a flash. Super amoled is amazing so super plus is better...what more could you want. We don't need to dwell on tons of worthless info. The phone is gonna be sick and the best anybodies had. Everybody wants it and so do I.

The core count dilemma

I had an iPhone 3GS. After I lost it now I have a HTC Desire.
My contract is expiring in a few months time and looking for another phone that will last me another 2 years. If I am going to use the phone for another 2 years, the hardware has to be up to the task. However I have problem with the latest crop of dual cores Android phones.
- LG Optimus 2x (despise the fake iPhone UI)
- Samsung Galaxy S II (despise the fake iPhone UI)
- Motorola Atrix (not available here)
- HTC Sensation (considering the Incredible S, not sure if it is rootable)
I could probably use a third party home screen for the Korean phones, I have tried most of them out there, IMO none of them are perfect. Zeam is not buggy, but doesn't scroll very smooth. Launcher Pro is very smooth, but occasionally pause to re cache (keep in memory doesn't quite work). ADW's elastic effect (so is Launcher Pro's) sometimes doesn't show up. IMO their features are superior in quantity but not in quality compared to vanilla Android or HTC's Sense.
On my Desire the AOSP ROMs tends to not fully utilise the hardware like the camera. I hope there are good AOSP ROM for them.
The phones that actually attracted me are:
- HTC Desire Z (has keyboard)
- SE Xperia Arc / Pro (Gigantic screen and pretty / has keyboards)
- Nexus S (I can imagine using it unrooted)
However they being all single core are kind of a side step from what i have now and worry they might get a little long in the tooth.
I considered the iPhone 5, on most aspect iPhone 4 is very nice to me, but it doesn't allow me to do simple things like USB file transfer, which is important to me. I also have a few Linux PC that doesn't do iTunes.
Thoughts?

There's no dilemma; buying a single-core in 2011 is downright stupid.

I bet my thunderbolt will give those dual core phones a run for there money...

other than the LTE speed, it can't touch a dual core. thats so stupid that its beyond comprehension. do you also prefer a single core pentium4 over an i7?

I wouldn't say it's stupid. Single-core devices will be pushed downmarket quickly and be more accessible. But I agree, anyone who tells me that a single-phone is a range-topping device is just trying to get a laugh

I dont think economy of scales has anything to do with single or dual cores, but rather that's the natural progression of electronics. Every handset will go down eventually toward their End-of-Life (EOL) cycle before they're replaced with newer ones.

Dude you don't have to be offensive.
Besides the gap between a dual and single core snapdragon is no where near between a processor today and one from a decade ago.
I don't play games, but I expect smooth UI. So the hardware is only part of the equation. As much as I like my Desire it is not as smooth as an iPhone 4 which is similarly spec'ed.
But if a dual core is what it takes to get that kind of smoothness on Android I'll pay for it. But once I paid for it I expect it to deliver as a package and not bogged down by some third rate software. Which is why I considered the Nexus S, which is as clean as it gets. The new Xperia line seems not bad from what I have seen even though they are single core.
Although the dual core Xperia will be a killer. But SE's history of software update may be a cause for concern.

We are in agreement but thats not what I meant to suggest lol. Having dual-core phones at the subsidized $200-300USD top end will force carriers/manufacturers to price down single-core devices to occupy lower price points regardless of how competitive they are on performance.
OP - Looking at all the hands-ons lately with the Atrix, G2x, SGS2, etc. it seems like having 2 cores amounts to a fairly dramatic difference in smoothness of the UI. I guess the question is what constitutes "smooth enough"

[Q] T-mobile G2x vs ATT Captivate(galaxy s)

i am confused between the 2
i need to get 1 of these for my loved 1
if i go with captivate i get Super AMPLED Plus screen
if i go with G2x i get Tegra 2 awsomeness
please help me through this problem,as both these are at comparable prices where i live,please dont suggest me about gettin galaxy s2 as that is way out of my range for the time being
looking forward to you people comments
Thanks

Captivate:
1GHz single core hummingbird (year old tech)
5MP rear camera (no front facing)
720p video capture
PowerVR SGX540 GPU (Corrected by Antigen)
16GB internal memory card
G2X
1GHz dual core tegra 2 (simply nothing comparable right now)
8MP rear camera
1.3MP front camera
1088p video capture
Tegra 2 Hardware Accelerator
HDMI mirroring (awesome feature)
8GB internal memory card (I have a 32GB external in mine, so I'm sitting with over 5GB of empty space on my internal memory card...so the extra 8GB of the captivate has no meaning for me, personally)
I have NO experience using the Captivate, so I can't help you with a comparison. But I can tell you that the G2X is the fastest phone with the most visually stunning graphics I've ever seen.
If you read this board, you'll read about some people that have had no problems with their g2x (I'm one of those), and others that have been plagued with problems. I dunno...for me, there's no question. I would buy this phone again if I had it to do over.

Yes, high def games seem to run smoother and appear brighter than on other phones I've seen. Your experience may differ, as this is my opinion.

Also the galaxy s captivate only has a super amoled... not a plus. Big difference.
Also big diferences with a single core vs dual core.
Also galaxy s has no reliable GPS.
The galaxy s has a blue hue also which looks horrible despite the deep blacks.
G2x has its fair share of problems too but they are just software related. I would recommend either waiting for the g2x to be officially updated and re-released or just grab the latest CM7 build....
Or wait for the Galaxy S2 to hit AT&T

Well, dude, if I were you - I'd have read some stuff about the phone before suggesting your opinions to smb.
Captivate has no GPU? LoL
Correct: All Galaxy S series (t-mo, at&t, verizon) phones have a GPU. PowerVR SGX540. Actually it's on par with G2x's Tegra 2 Geforce ULV.

You're right, I'm an idiot. The Galaxy S does have the PowerVR SGX540 gpu.
I apologize for any harm done.
I still don't believe the Captivate's gaming abilities are on par with the G2X when you consider both performance and efficiency. However, it is a top-notch gpu, and I'll retract that argument in my post.
And as far as offering my opinion before reading up on the Captivate? First, yes, I admittedly posted 1 line of incorrect information. All of the other information in my post is 100% accurate. Second, if you took time to read for yourself, you will notice that I specifically stated that I had no experience using the Captivate, so I couldn't provide a comparison between the 2 phones. I only posted spec differences as they were listed on the phone service provider's website. Why did I hurt your feelings?

I work for ATT and personal think the captivate is garbage.
We nicknamed it the Craptivate.
CPU is slow comapred to Tegra 2. Hell the hummingbird seemed slow compaired to the Snapdragon 1GHZ
Captivates camera sucks and has no flash
Touchwiz (samsungs skin) sucks
captivates GPS SUCKS
Captivate is 3G G2X is 4G
Super AMOLED has nice blacks but horrible whites.
If your looking at an ATT phone look at the Infuse 4G.
I currently have the G2x and the Infuse 4G. I like the G2x much better.
The Infuse 4G is pretty cool. And i hear the Galaxys S2 is pretty awesome.
But for the most part i dont think Samsung has put out a good phone since their Flipphones back in the late 90's early 00's

@OP
I have the G2x (or rather the Optimus 2x, same phone p-999 only it isnt T-mo branded)
A friend of mine has the Captivate and its no contest. Go with the G2x.
G2x has a better build (if you can find one without light bleed issues) and a much better feel in the hand compared to the Captivate.
Tegra 2 is a beast. I come from the Nexus One and then the Nexus S and i can assure you that the G2x blows those two pure google phones out of the water simply due to the Tegra.
Also, I have a Sensation 4G I'm playing around with to see if i should sell the G2x and right now im heavily in favour of the G2x simply because it is rooted and i've got custom kernels and ROMs on it. In fact I am only waiting this week for HTC to come clean with the bootloader before i sell it (temp-root isnt cutting it for me).
The G2x has a better screen and the Tegra is way better at processing multimedia than the Snapdragon (Google Maps app loads and processes map data 3 to 5 seconds faster on the 1GHZ Tegra than on the 1.2 GHZ Snapdragon).
Get a G2x, youre not going to regret it.

I would definitely go with the G2x. I've owned a Vibrant (which is very identical to the Captivate) and it has GPS issues which the Captivate is known for having also and the software has a great amount of lag unless you root it and install VOODOO LAG FIX. The Vibrant was a great phone once rooted minus the GPS. Just to be fair I can almost bet you money that if you post this in the Captivate forum (if you haven't already done so) that even Captivate owners would say the G2x is the better phone out of the two. We have the hardware to support just about any software android throws at us in the future. This phone is almost future proof.

New (Possible) Galaxy Nexus Specifications Leak

There's been yet another Galaxy Nexus specifications leak. I've written them all out on my blog to make it easier to read. But, the original leak comes from a guy on Google+. He's fairly active in the Android community (I'm told) so maybe he's trustworthy.
I think he guessed on a few things like: camera megapixels, processor clock, hardware/software acceleration. That's just my interpretation.
I lined up all of the specs he reported next to the ones from the ever-reputable Android Police.
My original piece: http://briefmobile.com/galaxy-nexus-might-be-even-cooler-than-you-think is quoted below.
Black = Jacob Epstein, Grey = Android Police
TI OMAP4 dual-core processor at 1.5 GHz
Texas Instruments OMAP 4460 processor
NFC
1 GB RAM
32 GB internal storage
No SD card slot
Possibly 1900 mAh battery
8-megapixel camera (maybe same as SGS2)
5-megapixel camera with 1080p 30 FPS recording
Bright LED notification light
LED notification light
Dual LED flash
4.6-inch screen
Large (possibly 4.65-inch)
Very light weight
Keyboard looks like a combination of Gingerbread and Honeycomb
720p screen (more vivid than iPhone retina display)
Touch sensitive bezel
Brings up on-screen buttons when touched
Google Chrome — “I’ll bet a lot of money it’s chrome”
Tabbed browsing
Faster pinch-to-zoom
Better animations and transitions
New LTE modem. 25/10 in speed test.
4G LTE
Extremely snappy UI
High quality plastic that feels “futuristic”
Very thin
Ultra battery efficient with Ice Cream Sandwich
Android 4.0 Ice Cream Sandwich
Individual notifications can be dismissed
No sliding door for USB port
Many app compatibility issues with Ice Cream Sandwich
Only takes “a few lines of code” to make an app compatible
Name “Galaxy Nexus” might not be final– might still be “Nexus Prime”
New “revolutionary” Google applications

Don't we all! I think these are reputable, though. I believe the Android Police specs, and these are mostly in line.
I think he guessed on the camera megapixels (thinking "oh it must be the same as SGS2") and on the processor clock speed. He thought that they were for sure, but I think they'll turn out to be wrong.
Justin Case says it's 1.2 GHz for sure. And, camera is most likely 5-megapixels as And Police said.

as long as it haves ICS ,two core cpu and the HD screen i don't care the rest...

My experience with different Galaxy S models

I want to share some experiences I have with the Galaxy S devices. It's a bit late to post this perhaps, old news even, since Galaxy S is no longer new and is only single core, but there are a few features that give these phones excellent value, especially for those who want to buy a phone out of contract and don't want to pay too much:
-Used ones can go for around $150, less if lucky
-Very easy and cheap to unlock
-Generally good battery life that can last whole day
-AMOLED screen, viewable under sunlight
-Good build quality (Gorilla glass)
-5MP camera takes decent pictures and 720p video with adequate lighting (most variants don't have LED flash)
-Decent graphic card (200 MHz PowerVR SGX 540) can handle all recent 3D games (ie. RipTide & Asphalt 6)
-Easy to root and has great developing community (CyanogenMod supports)
-Support "ODIN", easy flashing factory images in Download mode, making them very difficult to brick
-Used Wolfson DAC which yields great audio quality, which is not featured in the S II and Note
The Galaxy S variants I've owned are: S 4G (T-Mobile), Vibrant (T-Mobile), Captivate (ATT), Nexus S (T-Mobile). I have unlocked, rooted and flash roms on all of them. I also had the Galaxy SII and Note (International).
Overall impressions:
Nexus S: This has to be the most desired of the lot, best screen, best performance, latest OTA update directly from Google and has lots of developers for it. It has LED flash which most of the other variants don't. It also support Near Field Communications. However, it is not my favorite version.
Downfalls:
-no microSD card slot, only 16GB internal
-due to its curved shape, with a case included it can feel bulkier than other Galaxy S variants with flat body
Vibrant: This is my favorite of the lot, simply because it works on both T-Mo and ATT 3G, this is rare for an Android device this cheap. It's not pentaband however (doesn't support ATT 850mhz). It has internal 16GB storage and microSD expansion. Cyanogen support and lots of custom roms.
Downfalls:
-Needs GPS fix patch for custom roms, GPS lock time is a few seconds slower and less precise than other variants.
-(correct me if I'm wrong) It doesn't yet have the official T-Mobile 'WiFi Calling' app that the Galaxy S 4G has, but there is works on a custom version. IMO, you can just use GrooVe IP instead.
-No front face camera (I think there is a rare few Vibrants that does have it)
Captivate (ATT version): This device is the nicest looking Galaxy S I think, due to its slanted design. It feels just a tiny bit slower than the rest to me, I could be wrong, but it just feels that way. Like the Vibrant, it has Cyanogen supports and lots of developers, 16GB internal storage + microSD expansion. No front face camera unlike the Captivate Glide and Sprint's Epic 4G though.
Galaxy S 4G: There is a mix of good and bad for this device. It has good data speed (10Mbps+) as long as you live in a good T-Mobile coverage area, which also results in good tethering experience. It includes the app "WiFi Calling" so you won't use up minutes. Front face camera included.
Downfall:
-Lacks internal storage for users, needs to have microSD card. That also results in apps installed to microSD card by default, this can interfere with functions of some apps. Not sure if stock roms can do this, but you can always manually move the apps to internal storage, sometimes its a must for apps to autostart and for some app's widgets to show up in the widgets selection menu.
-Much less developers available, no CyanogenMod support. Only until now there is some work on porting CM7. With that said, the available Valhalla rom makes this device blazing fast, but also no longer worked on by its original developers.

Performance:
I'm not basing so much on synthetic benchmarks, but regular usage. The Nexus S seems the quickest and I achieved ~2500points for Quadrant. Aside from that all of devices I've used are on par, they all can play 3D games smoothly. They are all kind of slow with stock rom, but once you put in CyanogenMod7 or 9, they're blazing. In fact, I feel these devices with CM7 are more responsive than stock Galaxy S II and Note (in term of general navigation, of course newer phones are faster overall).
The Vibrant gets low Quadrant score, around 1500, but it seems just as fast as other ones. I feel the Captivate is slowest of the lots, but the difference is so small it doesn't matter. The key here is to flash custom roms.
Data speed:
The Vibrant is the best in term of value, it's not fast, but supports both 1700 and 1900 bands, so can work on both T-Mobile and ATT 3G networks, it does not support the newer ATT 850 band however.
S 4G: theoretical 21Mbps, I've achieved over 10Mbps
Vibrant: can get up to 6Mbps with good signal, generally stays around 2-3Mbps
Nexus S: theoretical 7.2Mbps, about same with Vibrant
Captivate: theoretical 7.2Mbps, but ATT HSPA network is generally slower than T-Mobile imo, it all depends on the area of coverage though
Galaxy S II (T-Mo): theoretical 42Mbps, I've achieved 24Mbps
Also note that with T-Mobile devices, I've been able to tether freely. I know that some people with the $79.99 plans have had text message from T-Mobile that warns tethering is not included with their plan.
GPS location fix:
These devices work pretty well as GPS navigator since their AMOLED screen remains viewable outdoor. They all generally takes around 6-10 secs to get a fix outdoor. The Captivate and Vibrant using custom roms required GPS fix patches. I have the most trouble getting location fix with the Vibrant which can take longer than 10 seconds. I've lost GPS signal on the highway with the S 4G with dark clouds overhead. These devices while does a good job, are not reliable as devices that include both GPS and GLONASS support, such as XPeria variants and the Galaxy Note, these can get really fast location fix and rarely lose signal.
Screen: The Nexus S has best screen quality than the rest of American carrier-locked variants, which all has 'blue tint' to them, although just as crisp details. However, if you have CyanogenMod9 installed, you can change the color temperature of the devices to warmer to match the Nexus S. There are no CM9 for the S 4G currently however.
Final:
If I have a final say about the Galaxy S model, is simply that it has Wolfson DAC, that is a big deal for audiophiles like me. The SII and Note just doesn't sound as good, regardless if they are more powerful devices. With that said, I recently got an XPeria Play which also has some excellent quality too, so XPeria devices might worth looking at if audio fidelity is your concerns.

Good Job.
I think Note is very big.
What Do you think the performance in games with Sony?
Cheers.

The Adreno 205 in the Play vs the SGX540 in the Galaxy are about the same performance, maybe the later edging by a bit. But the Play has a slide out gamepad which is unbeatable for gaming. However it also has terrible screen. And you need to unlock the boot loader to flash custom rom, and its not as easy if you don't have the international version. It is going too get official ICS release soon though.
I'm not sure if PS3 contoller also work with Gingerbread for the Galaxy devices, but the iControlPad can work with all apps just like the Play gamepad (using iCade mode and pairing with Bluez IME).
The Note international is the best device I've own by the time of its release, I think the SIII will take it to another level though. But the Note still has Wacom pen support which is useful.
