[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
How funny, I am in the exact same boat!! Returned my sprint phone and canceled service for a family plan with my gf where I'll pay about $10 per month because of her job. Data speeds are faster, but yeah, the phone itself is a shadow of the Sprint version, and i'm not even talking about the fact that it has LED notification, i'm taking about graphics, speed, jitter, etc.

But in the end I can't complain too much, going from $95/mo to $10 lol.

I am praying you are right!! I'm going to root just as soon as some custom Kernels start coming out.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
I am 100% correct that its a software issue. This processor is definitely capable of keeping up with Exynos once optimized.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
Err, no, it isn't. Exynos is superior in every measure, particularly in the GPU.

And do not expect Samsung to do any optimization at all. I mean . . . it's Samsung.

---------- Post added at 07:20 AM ---------- Previous post was at 07:18 AM ----------

I mean . . . put it next to a exynos SGSII. The difference is obvious.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
So you are saying that even with our software more optimized you will still notice the Exynos processor outperforming this one? I beg to differ. I think when test are based on paper then it's a different story, but day to day use you will never know the difference if the software is optimized correctly.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
That's a non sequitur. You can't "beg to differ" because the comparison you're referencing doesn't exist.

The fact is that exynos is faster, period. It's especially faster since touchwiz is not optimized for this processor -- which I highly, highly doubt Samsung will ever get around to doing.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
Thanks for the brief English lesson, now lets get back to business. If our software is optimized correctly how will you know that the Exynos processor is faster? Would you actually see and feel a significant performance difference between the two? I definitely know that right now the other Galaxy SII's are outperforming us but that is mainly because of well optimized software. I've played with an HD7 which has a 1ghz single core snapdragon processor and older gpu and you'd never know it until someone tells you or until you play a real graphic intensive game. The phones software feels buttery smooth! I think a lot of people are starting to blow this Exynos vs S3 processor out of proportion.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
Would you be able to see the difference? We don't know. Because TMO's SGSII is not optimized and probably never will be. That was my original point.

But all else equal, exynos is going to be better than this SoC.

Nobody is blowing anything out of proportion -- if you compare this model to the other SGSII versions with exynos side-by-side, you'd be lying if you said you didn't notice a significant difference. The trade-off is that TMO's version has by far the fastest data.
[T-Mobile Samsung Galaxy S II SGH-T989] mathieulh:
Sorry to kill your hopes fellas, but you should take a good look at my posts in this thread, this will show you how much of a disappointment the snapdragon SOC is next to the Exynos, it's more than just a matter of optimization. http://xdaforums.com/showthread.php?t=1172992
[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
This is exactly what I was fearing... :-(
[T-Mobile Samsung Galaxy S II SGH-T989] :
This is the biggest bull that's been in any thread people assume the snapdragon is weaker. Because it's a8 architecture. Let's take a look here on how wrong this is. Synchronization with processors will always be faster than Asynchronous processor under most normal conditions . Unless the Asynchronous processor is programmed correctly. The thread you show said basically htc sensation vs Galaxy 2 different phones. One samsung engineers may be quite better than HTC engineers.

We can even go to benchmarks. As if the processor is so much worst than a exynos we would not be scoring higher than the Exynos processor. You can't say let's overclock the Exynos 1.5 and see what performance you get since the Exynos is over clocked its going to run better as you are pushing its processor to the limits. You would have to do the same to the qualcomm processor as well.

Let's also talk about qualcomm processor you are never reaching both cores with 1.5 ghz one may reach it but then the other core may clock to about 800 mhz or 1 gig not 1.5. Samsung saw this as easy money they knew they could program the Touchwiz to work just as smooth as a exynos but they didn't why optimize a different processor. To show the potential. So they can have a reason for people to come buy. The samsung Galaxy 2 and 3 when it arrives. Basically they knew their device was popular and thats why people bought it.

GPU wise yes it is weaker I won't argue about. That as I said. Before mali-400 is more powerful but has weaker shaders and rendering than Adreno 220. Something says it about drivers. As source code is release and cyanogen and miui. Don't have a stable build for both devices them yet. But the bug list for the Sensation is scaling issues and 1080p recording causing a soft reboot which is way less than the Galaxy 2 bugs.

Just be happy with the device you have everything will be outdated by within a few weeks jumping to better phones for one processor which you won't see the difference on icecream sandwich or cyanogenmod or miui. Our phones are not at the point of of computers where I can't run this because I don't have enough ram or the newest i7 processor. Let's gets real point neither phone can run crysis.
[T-Mobile Samsung Galaxy S II SGH-T989] mathieulh:
That's not what my posts are about, read better.

Multiple benchmarks from different sources have shown that the snapdragon cpu core is about 20% to 25% slower at equal clock speeds than an ARM A9 core, that's why the snapdragon's arm core on the MSM8260 was pushed to 1.5Ghz (300Mhz higher than the Exynos's A9 ARM core) to achieve similar performances (and even then it's slightly slower because the cpu and gpu share the same bus and pipeline (although the pipeline is now 128bits) which means that if the gpu is pushed too far the cpu has to wait until the adreno handles its queued instructions, this means you eventually lose a clock cycle, that alone isn't much of a performance issue, but 1+1+1+1... = way too many

Of course you are, as soon as you use anything cpu intensive that is, then the adreno performances suffer because they have to wait for the cpu to handle its task (remember, both use the very same bus), so either way if you use the cpu or gpu at full capacity, you can expect a 10 to 15% performance loss at either the cpu or gpu (depending on which one you're using), if you are using both at full capacity, you can expect a greater loss of which the average can reach up to 20% (All just because qualcomm wanted to save money by using a single bus for the cpu and gpu, something competitors had the foresight not to reproduce)

You would know how bad it is would you have taken the time to read my posts. Qualcomm SOC are low cost SOCs sent to vendors (in this case, cell phone manufacturers) with very low support from the SOC manufacturer (in this case Qualcomm) which sells the driver sources as a separate package (that tells you much about how badly they collaborate with vendors)

This means you have more chances of winning at the national lottery than expecting qualcomm to provide support to a vendor regarding driver optimizations.

The only reason Samsung even considered using a qualcomm SOC on a Galaxy branded device was their lack of choice in the matter, basically T-Mobile wanted their home flavour of the galaxy s2 to support a 42Mbits hspa+ connectivity and Qualcomm is for now the only manufacturer that provides basebands compatible with 42mbps hspa+ on AWS bands, obviously because it'd be both too expensive and power hungry to fit both an exynos SOC with a MSM8260 qualcomm SOC (not to mention Samsung are currently experiencing Exynos supply shortages) they made the choice to come up with a galaxy S2 on MSM8260 SOC.

The Galaxy SII being Samsung's flagship, they obviously did their best to optimize their touchwiz interface and kernel drivers to the MSM8260, sadly there is only so much they can do with an almost total lack of support from the respective Qualcomm division.

It's not about drivers, the adreno220 is a lot weaker hardware wise than the MALI-400, as to 1080p decoding; the Exynos SOC sports a dedicated h.264 decoding/encoding hardware which allows it to play back and record 1080p high profile videos without so much of a hiccup, something the MSM8260 does not have either.
[T-Mobile Samsung Galaxy S II SGH-T989] hazard99:
My gawd. Either return the phone or be happy. And who is to say Samsung won't optimize the software. So far they have done everything differently than with the vibrant. Sometimes this stuff is depressing . It may not be as fast as the sprint or att version. But I'm happy. Btw did any of you play with the phone before you bought it ?
[T-Mobile Samsung Galaxy S II SGH-T989] iPathik:
Arent you the same guy that modified the PSP and PS3?
[T-Mobile Samsung Galaxy S II SGH-T989] mathieulh:
Indeed I am.

P.S. On a sidenote, the SGH-T989 is still a very good android handset achieving higher than above average performances (although not as good as the one the Exynos SOC provides), supporting a great connectivity (the baseband part of the MSM8260 is actually a lot better than the XMM6260 from infineon/intel that fits the I9100) and a very good screen, in the end it all comes to your priorities (connectivity/screen over performances), and carrier. (Is your carrier using AWS bands ?); Android is also a world of choice and openess, there are other handsets that might fit your needs and work on AWS carriers as well. (Galaxy Nexus anyone ?)
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
Anyone that thinks the T989 can't keep up with the i9100 when playing doodle jump because of the SoC horsepower is a insane. It has nothing to do with the differences between the two and more with optimization for the game and maybe even on Samsung's part. Samsung's drivers might not be playing well with the game, and the game might not be playing well with Samsung's drivers.

EITHER WAY, the Adreno 220 is more than capable of playing Doodle Jump and quite frankly I'm sick of hearing about that lame game. The dev hasn't even updated it since MARCH 2011!
[T-Mobile Samsung Galaxy S II SGH-T989] PoisonWolf:
Try playing Dungeon Defenders and see which GPU holds up better. ;)

P.S. OP, your question is silly and pointless. You're asking that in a T-Mobile section. Everyone will never admit to having paid or signed away 2 years for a phone that they will openly admit as being inferior to the others. Or if they do, they would argue it as being irrelevant at the grand scheme of things. It's called cognitive dissonance. Lawl.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Its something in the drivers as mytouch 4g can play dungeon defenders perfectly fine and smooth with no lag. In the game so idk whats the problem as the mytouch has adreno 205 which weaker than both adreno 220 and mali 400 by a lot.

---------- Post added at 09:35 AM ---------- Previous post was at 09:14 AM ----------

I understand exactly what you mean after i read it over. My friend has a Samsung epic touch 4g the sprint variant of the galaxy. I think that's the name. His is smoother over round ui. But somethings i beat him in as his web browser is smoother. I do load pages faster. His has no checker boarding though. When we both on wifi. We both are playing dead space but seems to be no different in performance.Even apps open the same speed. Seems as if only the ui and browser. So this will probably all be nullified with hardware acceleration from ice cream sandwich.
[T-Mobile Samsung Galaxy S II SGH-T989] barondebxl:
2 cores clocked at 1.5 ghz each is morpower than anyone need. Its just the optimization. Yes the exynos is better but the qualcomm is very good. Just optimization.
[T-Mobile Samsung Galaxy S II SGH-T989] Born_Immaculate88:
Specs wise the T-Mobile Galaxy S II blows the others out of the water.

1.5 Ghz Dual-Core Snapdragon S3, 4.52 inch display, Android 2.3.5, Standard battery, Li-Ion 1850 mAh. The biggest differences are going to be in the smoothness of operation on the phone. The Exynos processor is higher quality and runs more smoothly because of the optimizations done with it. Snapdragon processors have always been criticized for choppy/laggy performance on devices. A few tips to get the system running more smoothly would be to root the phone, download titanium backup and get rid of the bloatware. Flash a Rom that is Bloatware free, or even overclock the processor (this will affect the battery life negatively) hope this helps.
[T-Mobile Samsung Galaxy S II SGH-T989] mathieulh:
The Snapdragon S3 is not near as fast as the Exynos SOC, not even with optimizations in mind (which either way considering the lack of will from qualcomm to provide support to vendors is unlikely to ever happen, you could already consider that Samsung has provided the best optimization they can for the Snapdragon S3 SOC) Even should the MSM8260 SOC be an inhouse chip from samsung with fully optimized drivers, it would still not be as fast as the Exynos at 1.2Ghz, sorry the differences between both architectures are just too great and create a huge gap when it comes to performances. The Exynos is most likely the best SOC available on android phones right now, the Snapdragon.... not so much.
[T-Mobile Samsung Galaxy S II SGH-T989] phewizzo:
Listen! Exynos > Snapdragon. But I know T-Mobile Galaxy S 2 is the fastest snapdragon phone in the world right now and im happy with that. Im happy saying my phone as of this moment is the 2nd fastest phone available in the world right now until the Nexus comes out. Us Tmo Galaxy S2 owners should be happy, our phone out performs the Amaze 4G and that phone is way more expensive. I will never go back to HTC again in my life. Almost all their phones have touchscreen accuracy problems.
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
I did have issues with my Sensation even after the 2.3.4 update. It was much rarer tho, the lockscreen problem that is
[T-Mobile Samsung Galaxy S II SGH-T989] :
a9 architecture is still better than a8. You would need a hell of a lot time of optimization to make it better though possible but it isn't worth the time and effort. Next year the snapdragon s4 we be using some same heavily customized a8 based on a15 architecture. So much so that Qualcomm actually makes its own new architecture based on 28mn. Same asynchronous design. Have no idea what their doing over there:confused:. But the new exynos is 4212 28mn it seems not only does that processor has now an overclocked gpu twice as much as the old one. But it now 50% faster. Samsung will probably be in the lead again followed by snapdragon , Texas instruments , and kal el. Unless Intel gets in the game and brings intel atoms to phones wont be much more than the same thing next year.
[T-Mobile Samsung Galaxy S II SGH-T989] PoisonWolf:
Wrong.

Exynos > Snapdragon.

Not because of the brand, not because of whatever reason you can think of.

Simply because the Exynos is A9 architecture and the Snapdragon is A8 architecture.

Notice how the Sprint and ATT versions do not have to go through the hassle that you go through just to get a "smooth" phone. :)

I love the phone and all, don't get me wrong. But I'd prefer if users in this forum not spout opinions as fact. The Snapdragon is simply inferior to the Exynos. No matter how you spin it, how you justify it, or how you reason it out for yourselves. Technology simply doesn't lie.

Having said that, I still love this phone despite these drawbacks simply because it's the best that's available on T-Mobile's selection now. I'd love to get one but I'm going to hold out till the manufacturing and assembly process have successfully iron out the kinks that's causing the lottery with faulty displays.

Woah. I'm looking forward to Sammy's new little beasty homunculi ! =D

Imagine those steroid-driven GPUs on HW accelerated ICS or even WP7. That would be hands down epic in terms of performance.
[T-Mobile Samsung Galaxy S II SGH-T989] :
When ice cream sandwich launches on phones it probably wont be as different as as gingerbread with full fledged hardware accelerated unless you have a g1 gpu you shouldn't be lagging. Everyone should be in the matter of screen size and manufacture designs. This is without custom ui's of course. Well at least htc can finally get sense to run decently now:rolleyes:
[T-Mobile Samsung Galaxy S II SGH-T989] ctkatz:
starting to? where have you been since the end of august friend? spec freaks have been mad since that time failing to realize a) the average user doesn't care and b) that if you can't tell the difference why freak out over it?
[T-Mobile Samsung Galaxy S II SGH-T989] PoisonWolf:
I understand that you love your phone very much and that you can't stand the idea that this phone isn't great.

Optimized or not, the Exynos will eat the Snapdragon alive. Qualcomm is using old architecture (A8) versus the Exynos (A9).

Not matter how you want to tell others or yourself, just embrace the fact that our Tmobile GS2 is inferior to the others.
[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
Yes, it's more than capable of playing the game, BUT WITH AN ABUNDANCE OF DISTORTION AND JITTER, WHICH IS MY ENTIRE POINT!!! I'm not calling out the processors or optimizaion, JUST THE PHONE ITSELF SINCE I HAVE OWNED BOTH. Face it, the Tmo version sucks vs. the others, GET OVER IT ALREADY!! All anyone has to do is download and play this simple 2d game next to any other smartphone on the globe and you'll see just how pathetic this phone really is.

Sorry, but I didn't make the phone, I just own one and am a little upset at how much this one drags vs. the other versions.
[T-Mobile Samsung Galaxy S II SGH-T989] cashyftw:
I agree with this completely.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
I do love my phone I know it isn't perfect, but once it is optimized accordingly it will be hard to tell the difference between the two processors in day to day use. Some of you guys are going off of what paper says. Just like how T-Mobile claims 42mbps. I know the Exynos is faster, but once rooted or optimized correctly you will never know that this phone has a slower processor. Are you guys looking to play Xbox and PlayStation games on your phone? Day to day use I've played with a rooted myTouch 4g that felt like it was dual core. Software plays a big part just as well as hardware. You probably are a QUADRANT STANDARD believer. I never said our processor was faster. Remember these two words. OPTIMIZATION & SOFTWARE!
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
So you actually think no matter what you do this phone will be slow and jittery when playing games? That makes no sense at all! I can't wait till the kinks get worked out so I can say I told you so. How does single core phones with older technology play graphic intensive games? Yes processor plays a part, but bashing our processor like its horrible for games etc does not make any sense. Why isn't a Snapdragon S3 not more than enough to play games, browse the internet, etc? Yes I'm slightly upset with Samsung and T-Mobile for not working out the kinks as much as they should of, but once its worked out we will have a beast.
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
You're pathetic if you really think it's not capable of playing your lame ass game you keep *****ing about
[T-Mobile Samsung Galaxy S II SGH-T989] :
Um you do know there at least about 7 diffrent versions of doodle jump in the market lol. Not a really big deal just go back to your old phone to play the game. The game isnt even that great. Now if it were dead space then ill be angry:confused:
[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
Sorry, i'm not pathetic, the phone is. I fulfill all my work obligations accordingly by meeting or exceeding all expectations. This phone does not, and it's clearly visible whilst playing this stupid game. Sorry, don't ***** to me for pointing it out.

[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
Look, i'm not "bashing" anything or anyone, just stating a fact that, for whatever reason, phone, processors, optimization, service, whatever, this device simply cannot handle the game Doodle Jump while all other variants can.

Not bashing, just stating a fact. Write Samsung or Tmo, not me I didn't create this damn phone, jeez.
[T-Mobile Samsung Galaxy S II SGH-T989] PoisonWolf:
You sure are one to get pissy when someone points out a negative point about the phone.

I don't believe in quadrant standards. My NookColor shows 2700 whilst some people here are reporting 2500 ~ 2700. See what's wrong with that?

Don't be quick to pass judgment.

I love this phone, but I am appalled by the number of people who go around saying that this phone is the best of the fleet, how it's better, etc. Or how it would be a god-phone once XDA gets to work on it. The point is that the other variants do not even have to do this.

Remain objective. This is the most important part of any smart consumer.
[T-Mobile Samsung Galaxy S II SGH-T989] Astitious:
I have yet to notice any lag and I don't really care if certain phones on other networks are theoretically better at playing a couple apps. I hate AT&T and Verizon, and Sprint sucks where I live, so T-Mobile is my only choice.

If you look at the entire package (cost of ownership, network speeds, application performance etc) then I really doubt any other phone beats this one. But this will all change in no time as there is always something better around the corner when it comes to Android phones.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
Since you have an issue with this phone you should be the one writing Samsung or T-Mobile.
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
I never act like this phone is perfect or was in the same league as the other variants. I just stated that we need our software fixed correctly and all those games etc will work accordingly.
[T-Mobile Samsung Galaxy S II SGH-T989] ap77:
This. This is an alarming amount of purchase justification trolling going on around here with respect to this phone. I haven't encountered this with other devices -- maybe I'm just lucky.

The fact is, this model has certain drawbacks (and some advantages) as compared to the exynos models. You would think this would be a non-controversial statement since it is 100% objectively true. But I guess not....
[T-Mobile Samsung Galaxy S II SGH-T989] OuncE718:
There is slight lag, but not enough for these guys to say this phone sucks because it can't play a game because of proper software optimization. The game not playing well could easily be one of 3 things. A slow processor (which we don't have), a game that is just not optimized for our phone or our software just not being optimized for the hardware. Our hardware is more than capable of getting the job done and more. Did these guys forget about the G2 that came with a 800mhz processor or the Nexus S that is still able to play such games pretty smoothly? We do not have a hardware limitation guys so stop stressing the processor.
[T-Mobile Samsung Galaxy S II SGH-T989] Matt -- HB Cali:
