If Nexus S (2?) has similar hardware to Galaxy S, is it easy to port 2.3?

Even though I have followed dev/porting for 8 months starting with HTC Touch, I have little knowledge of how it is actually done. So here's my question to the developers.
We all know that Nexus S (2?) will have Gingerbread 2.3. Looking at the rumored specs and model number, it seems that Nexus S is a slight upgrade from Galaxy S.
Assuming most of the hardware is identical to Galaxy S, how easy is it to port 2.3 to Epic 4G, once Galaxy S becomes available?
Specifically, what is needed to bake a new 2.3 rom? Do you need to reverse engineer like what devs did on HTC WM devices? Or is it a straight port? I suspect it's somewhere in between but want to hear from you.
(If necessary, please move this to android development forum.)

The simple answer to this (which has been answered in other threads already if you looked) is no its won't be easy.

Also, the Nexus S is rumored and pretty much guaranteed to launch with a dual core processor. The rumor is that they delayed the device and gingerbread to implement this, since it will be google's new flagship device and has to be cutting edge. Everyone knows that dual core processors are set to hit the market within the first couple months of 2011 anyway, so releasing an old generation processor in a flagship google phone just makes no sense.
So no, it will not be easy to port from the Nexus S. It will not only have a completely different processor, but will also probably only be a GSM phone.

I agree and think this is the bigger problem (for the Epic at least).
Sure would be nice if the folks at Google would release at one clean Google device for each carrier. I'd be on it in a heart beat.

Yes that would be nice if they did that.I am surprised they are even doing another google phone by the way it sounded when they stopped marketing the nexus 1 that had no interest in doing another google branded phone.

Those are just rumors, all of the official specs that have come out say it will be a 1.2ghz hummingbird. The dual core 1ghz orion chip is definitely on the horizon but I highly doubt they will be able to get it in at the last minute, and there's a good chance we won't see it in phones until late next year. All rumors of a dual core Nexus S have had no credibility with their sources.
That said, if this turns out to be a dual core phone and gingerbread turns out to be optimized for dual cores, a port will probably be very difficult. But if it's just a 1.2ghz hummingbird then it would just be a matter of getting the CDMA radio working.

The reason that I think he has to have a dual core in it is as follows:
If it has a 1.2 ghz hummingbird processor, BFD. It immediately launches and is mediocre. Nothing exciting at all about it.
If it launches as the first dual core phone, it is the top of the line phone worthy of being branded as a Google flagship device.
Also, if it just had a 1.2 ghz hummingbird processor, what is the holdup? It is no different from phones released months ago. Also, if its a 1.2 Ghz processor, it will be eclipsed within a matter of a month or two performance wise by Tegra 2 and dual core snapdragon processors. Basically, it would be an embarassing flagship device. The original Nexus is still to this day a damn good phone that is near the top of the pack of android phones performance wise, and it is a year old.

You are fully aware the the Tegra 2 do not even exceed the hummingbird in gpu or cpu performance right? Im just saying cause it would suck if you didn't know what you're talking about.
Plus gingerbread will have HW acceleration, putting gpu performance on a step for the overall fluidity of the gui. So again... what's faster?

Really? I assumed it would greatly ourperform. Where did u get your facts.

I'm trying to find the article again, but i know they were close but Tegra 2 did not outperform the hummingbird. Apparently now they optimized the platform more.
Don't get me wrong i love nvidia, that's all i've purchased and stayed with them even thou they still dont have a decent dx11 card that doesnt need 2 power supplies. But they really need to step up and their CEO needs to wattch what he says and deliver more.
Here's a quote "On the 3D side, Nvidia says it has doubled the performance of the initial Tegra, resulting in a peak speed of 90 million triangles per second. This level is well beyond the performance of any mobile processor shipping or even sampling today." Hummingbird has the same exact performance. And CPU performance is a very interesting area. Anyway the GPU performance is almost par with the Hummingbird leading maybe by 3-5%

Since Tegra 2 is dual core and android does not have 2 core support till Gingerbread (Actually I don't think it even supports cortex A9 till gingerbread)..so if they ran 1 core vs 1 core I'd see a hummingbird win against a Tegra 2..but if Tegra 2 is running dual core (and optimized for it) it should win...but by that analogy Orion would then be superior.

Not to mention that Tegra 2 does 1080P video recording. So yes, releasing a google flagship phone that within one month is eclipsed by LG with the first Tegra 2 phone, would be embarrassing. The Nexus 1 set the standard for almost a year, before the Galaxy S line came out. If the Nexus 2 can only set the standard for under a month, that would be stupid. Therefore, it is easy to conclude that the rumors of the Nexus S having a dual core are most likely true. Doesn't mean it has to be the Orion, but it would be awesome if it was.

Tegra 2 is a Cortex A9 CPU... as is the Samsung Orion and the TI OMAP4xxx chips. They accomplish 2.5 instructions per MHz as opposed to the 2 instructions per MHz in the Cortex A8 Hummingbird, and that's not counting improvements to instruction efficiency (getting more done with less instructions.) Add to that improvements such as out of order instruction handling and dual-channel memory support and Cortex A9 chips are head and shoulders above Cortex A8.
The only reason Tegra 2 wouldn't outperform Hummingbird significantly is, as mentioned, lack of dual-core support in current builds of Android, and the nVidia GPU which is, surprisingly, only just about on par with Hummingbird's PowerVR SGX540.

I'm not sure that triangles per second is accurate to describe performance.

Here's the facts dude, and try to get this; Tegra2 does not, in fact, suck. You just posted a video of it being benchmarked on a netbook running Android 2.1 which cannot make full use of Tegra2's dual-core CPU. Secondly, neocore is a GPU test, not a CPU test. We already discussed the fact that the Tegra2 GPU is only just about on par with the SGX540. Thirdly, that test is being run at a signifcantly higher resolution than a mobile device would run, and frankly, considering this, the score isn't bad.
Fail, man, fail.

I would also like to point out that I wrote the article that sauron0101 just linked. It's also posted on my blog (linked in my signature) posted back in March. Tegra2 does feature dual-channel memory support as part of the Cortex A9 architecture, which is a significant advantage.

Any idea how fast the other Arm Cortex A9s are compared to the 250?
- We know that the SGX540 will be in the TI OMAP 4 series; probably not bandwidth limited - I am surprised that they did not opt for the SGX545
- The Samsung Orion series has Mail 400 (unknown performance)
- The Snapdragon (A8 unless Qualcomm opts to keep the name "Snapdragon for its A9 CPUs) will have a new generation of Adreno 300 graphics
Unknown if we will see this on mobile
- Marvell also has a new SOC
Also interesting is Samsung's Netbook roadmap, which uses the same SOCs on a phone:
Sorry if all of this is a bit off topic, but it is worth looking at what everyone has.
Edit: Qualcomm is keeping the Snapdragon name for the A9 processors.

Does no one see i was talking about Gpu perfomance? That's what's gonna matter in Gingerbread. And that's running 1024x600 on that res Galaxy tab is around 53 fps. It's the same thing that Vista started doing with HW accel so u understand.

Dual-Core phones (Sprint)

I'm starting to notice now that so me are hitting the market. Surely Sprint will lose customers if they don't come out with one soon...
I've seen the echo and I couldn't care less about dual screen....I do care about dual-core though. Has anyone heard of a rumor or announcement regarding Sprint's first dual-core phone?

Our SGS2, and it will ship with 2.2.1, but 2.3 will be soon to follow, enabling the 3g and 4g radio features. No, really, idunno what sprint has up their butt, probly another overhyped HTC. Or will they try to resurrect palm again??? RIM? I swear they got the brown acid at headquarters... the echo is beyond dumb, no more premier unless you pay for landline minutes nobody uses....???

Just curious why you want dual core outside of saying that you have it? Is there some app in particular that you use that will be updated to use both cores? Most apps that run in the background have so little overhead that a bump in speed is far more beneficial than adding another core. I'd like to have the option of a single multi-threaded core or dual core. I'd take a 1.5Ghz multi thread single core over a 1.0Ghz dual core any day of the week in my phone. Not sure if there is a single droid app out there that would actually have any benefit of another core at all???
I think true benefit would come from a heterogeneous processor design that basically fed all of the 'phone' functions to a 100Mhz or so core that did nothing but "basic" phone functions. Any graphics or other type processing would rely on the video unit as well as the "high speed" core, which is typically switched off when the phone is being used as a phone, or is idle waiting for a call, etc.... The video cpu should have adequate ram to store icons and stuff of the such where screen rotations, page flips, etc... should be instantaneous. There shouldn't be any lag when rotating orientations and what not. Battery life could be significantly greater using a low power/speed cpu when that's all that is required.

I agree with the last post. The only reason to upgrade to a dual core phone today is to future proof yourself and maybe a bit more efficient battery usage. Seems like as it stands now, it's the eqivalent of buying a high end blu-ray player just to watch standard DVDs.

I have been reading the forum for a while now and the only use I could tell would be compiling packages or roms. Dual core would definitely help with that. Outside of that it would just be a benchmark machine. There are two ways to use a dual core chip. Either you can program code to run across both cores at the same time(which most programmers do not do if you couldn't tell from the computer side). The simplicity of apps does not really generate a desire for programmers to do this. The other is multitasking. You can run more than one thread at a time since one is going to each. I can't see this helping all that much unless you have programs that run in the background.
I can however see it draining battery. But to each his own.

I bought a ps3 when blu-ray first came out and now I don't have to waste money on a 3d-player
I want a dualcore phone solely for the fact that I'll be futureproof.
Unless its like the epic, I'm not gonna uprade tho. The epic is probably the best single core phone, so hats adequate enough to hold me down until october
Sent from my SPH-D700 using XDA App

October sh...t ill wait 2 years before i get another phone. let them really get these bugs of the dual cores fixed and smoothed and to let the carriers catch up in the upgrading of android. unless there are some really sweet features that i cant live without and we cant get modded to this phone.

I'll probably wait until they iron things out and see if there will be more implementations to take advantage of the dual core feature, rather than purchasing the first gen models.

Well...to put into perspective of the futureproofability of the epic....the g1 just got a half working port of honeycomb LOL

The PS3 is 5yrs old already. It took more than 2 years for titles to start hitting BluRay regularly. And since that time, the $500 PS3, dropped $100 after just 1yr, and came down another $100 2yrs after that. I'm betting against the "future" having any use for the dual core cells dropping now. Sort of how the future has nothing to do with the Galaxy Tab. By the time the software is written to utilize the Tab, it will be an Atom amongst i3s. If it can run 3.0, it will be so painfully slow that you'll toss it out the window. You may have plans for the 'future', but the future will have no plans for you Why don't you just save $$ by using one's head, and buy things when they can actually be utilized? You haven't had the epic but at most 7 months......keep it a full 2 years and grab the 2nd run of dual cores that have issues sorted out and software to utilize it.
Sort of like buying a USB 3 card 2 years ago for $100 when nothing utilized it. Now that devices are actually releasing for it, they're $27

I am aware technology tends to advance quickly, but why would I want to buy something that would be outdated by the time the next best thing comes out?

Intel mobil .24nm dual core FTW!
Seriously, I don't see how the Galaxy 2 will not have horrible battery time.

As long as they stay away from that Tegra 2 stinker of a dual core. What a let down that is.

Haven't seen a carrier yet. Its a damn cool phone and would be awesome for Sprint. I am not into the whole 3d thing yet, but having that option is kind neat. The hardware though, omg the hardware makes me drool.
If only we could overclock our powervr sgx540 gpu, that would be amazing. Not much use at the moment, but if we ever got microusb to hdmi out it would be able to play 1080p as well as the 720p its currently capable of.
Edit: Damnit, T-Mobile gets all of the amazing phones.

I do plan onkeepingthe epic...its basically the epitome of the single core generation. The only way to one-upit is with dual cores. By the time I have to upgrade, quad cores will be out.
I hate how fast tech gets aged...but the hummingbird is more than dequate for my mobile needs....I mean come on. The epic has been out for 7 months (the galaxy s has been out since may I think...) and only NOW are phones/tablets catching up to its capabilities.
I'm probably not gonnaget a dual core phone. But I wouldn't mind a dual core tablet to compliment the epic for when stuff gets real serious and I need to whip out the pc-grade stuff

I check the GLbenchmark website just now,found that the result of i9100 is now public.
Captured the pictures for your convinience.

If the benchmark only runs at native resolution then this is useless because the iPad has a much higher resolution, therefore it would perform worse. Of course if it runs at a fixed resolution I couldn't be more happy.

I know maybe it's a little bit unfair,it runs at native resolution,but still impressive.
And I did a little calculation with other model's results,the 25% more pixels leads to 12.5% less frames.
iPad 2 have 100% more pixels than SGSII.
(all proximate value)
1.25*1.25*1.25= 2;
0.875*0.875*0.875 =0.67;
So if SGSII has a iPad 2 resolution,the benchmark would be one third less.

Well for me it seems that sgx543 has better performance. But good thing is that it wont be that much.

I don't think performance is really that important, tbh. It's all about the kind of games that will be developed for the platforms. For example, even though the original SGS with its sgx540 is FAR better than the iphone 4's sgx535, the quality of games available and its graphics are much MUCH better on the iphone 4. I have both the gulf in class between the two when it comes to the quality of the gaming library is absolutely enormous, and only the tegra 2 phones have done something to bridge this gap for android phones.
One can only imagine the kind of awesome games that will be developed for that beastly sgx543 for the iphone 5. I just hope that the majority of the games will also find their way on the android market and the SGS2 (and not tegra zone), with its ever growing popularity because the mali definitely has the capability to run those games well.
Personally, i feel that the next iteration of the Xperia Play will be the ultimate device for hardcore gamers, beating even the iOS devices at the time. The current one is the ultimate emulation phone thanks to its brilliant gamepad, and runs all oldschool PSX, N64, SNES etc. games with aplomb - and if you're into that kind of thing then it's an absolute joy to behold.

No, most of the scores i've seen and done myself are around 40-44 fps for Mali, NOT 50 fps, I'm not sure what they've done to get over 50 fps but that's not what the phone normally scores.
Also theres a resolution difference.
EDIT: Just rechecked it's on Top not Average, when looking at benchmark numbers you need to look at the average framerate.
It's actually 46.7 fps or the iPad 2 and 40.2 fps for the Galaxy S II.

If the xperia play has good quality N64 roms, my SGS 2 is going back to mr orange

Honestly benchmarks mean nothing if there's NO apps.
and take it from me, my iOS library is over 600 purchased apps and games, and I've got around 20 purchased games on android.
That's a huge difference, I literally KNOW of every game almost in existence I get them RIGHT away when they come out. I know the very vast differences in choices from Android gaming to iOS.
and I always miss my iOS games when i'm out (android phone) it's a good thing my iPad 2 gives me the Fix I need. =D
for you iOS gamers out there, seriously try out a game called "Battleheart" It will devour your soul... freaking epic game...

You'll be amazed: http://www.youtube.com/watch?v=qYodquYXArs
tbh every android phone can run n64 games well i guess, what sets the play apart is that there aren't any ugly and cumbersome touch controls taking up the screen.
But the fact remains that the SGS2, apart from the above, does everything else SO much better!

How many cores?
Can someone confirm if the Mali400 used in GS2 using multi core? I believe I read somewhere that Samsung decided to use only a single core for the GS2.

I think you can find some game pad for android on sale in the near future,since Gingerbread 2.3.4 supports Open Accessory API.
So you can connect to a pad when you play games,and get rid of it when you don't.

Based on some of those scores, it looks like it's hitting the 60fps cap

Even at higher res the exynos scores great, check the hard kernel benches =) their tab uses the same/similar chip

Bear in mind that the GPU in mobiles tend to clocked lower than that in tablets to keep the power consumption down. So diffcicult to do an apples for apples comparison (excuse the pun) in this case. Will have to wait for iPhone 5 numbers.

What i have read is that it uses a 2 core model. The 4 core model is headed for the Sony NGP.

That's the PowerVR SGX543 you're thinking of. The iPad 2 uses the dual-core variant, the NGP will be using the quad-core variant.
The GS II has a quad-core Mali-400. Anything less, and it would never attain the results it's currently getting on GLBenchmark.

The Pro test that's the case but it's not wit the Eqypt test, max is around 50 fps so it never even reaches 60 fps.

NVIDIA Tegra 4 vs Nexus 10 processor

They've unveiled it today
http://www.engadget.com/2013/01/06/nvidia-tegra-4-official/
and apparently it's much powerful and faster than the eqynox on the nexus 10, but I don't know that much about this kind of tech, I'm probably finally going to buy the Nexus 10 this week if Samsung doesn't unveil a more powerful tablet, so I was wondering if this Tegra 4 processor is worth waiting for until it's implemented on a tablet.

May TEGRA 3 Rest in Peace ...

Yes that thing is packing heat. Best case, the next device with a tegra 4 will come out next Christmas. Unless they've been hiding something.

i think march....mark my words

Their browser test is having the Nexus 10 run Chrome while the Tegra runs AOSP. In my eyes that makes it a 100% unfair comparison.
Between bad experiences with Tegra 2 and 3 (Atrix/TF700) and their requirement that Tegra optimized games not run on other SoC vendors without any real reason other than because they can, I cant even consider a mobile Nvidia device. All they're good for is keeping the more reputable chip makers on their toes.

yes it's nice

Would be interesting to see this with both devices running the AOSP browser! From my experience it is much faster than the current chrome version (which still is version 18 on android, compared to 23 on desktop). Maybe the Tegra4 would be faster aswell, but not that much.
Everything on my N10 is extremely fast and fluid, so I wouldn't wait for whenever the first Tegra4 devices will be available. Plus its Nexus so you know what you are buying!

Agreed, they're making an Apples and Pears comparison that was undoubtedly set to show the new processor in a good light. It's only to be expected, it is a sales pitch after all. It will no doubt be a faster chip though.

I would much rather see a couple benchmark runs myself. A time comparison of a web browser is no way to test the power of a new chipset.
Still, I would expect Tegra 4 to be WAY WAY WAY more powerful than the Exynos 5250. Both devices use the A15 architecture, and Tegra 4 has twice as many CPU cores as we have. This alone is already a big boost in multithreaded apps. Then look at the GPU where you cant even compare the two at all except by end result numbers. They are just far too different. We have 4 GPU cores, Tegra 4 has 72 GPU cores. But those cores are designed far differently and not nearly as powerful per core. It is all about the companies definition of what a GPU "core" is. And then you have a smaller process node as well, which by itself already promises to use less power than the larger process node the Exynos 5250 uses.
I would honestly expect the Tegra 4 chipset to completely destroy our tablet in terms of performance, but a much more fair comparison would be to compare the Tegra 4 to the Exynos 5 quad. Those two are actually designed to compete with each other.

If you want to compare exynos and tegra 4 then wait for exynos 5450 (quad a15) which should come with galaxy s4 no of cores makes a difference here t4 is quad but early gl benchmarks show that A6X and exynos 5250 have a better GPU

Lets hope and pray Vizio managed to add microSD capability to it. Free of Nexus restraints, it should be doable, but since it is running stock JB, the storage would have to be mounted as USB (?) . So far this Vizio 10" was the most exciting Android development out of CES. We have few more our of Press events scheduled in Vegas and then it will be all over

The new iPhone 5 doesnt use the same ARM architecture are the S3 though, it is a custom design. So those can be compared against each other fine to see which architecture is better. And if a slower clock speed CPU gets better scores then we know it is a superior design. This is the basis of all benchmarking. If we were only allowed to compare the exact same architectures together then we wouldnt learn anything.
Tegra4 uses a (probably slightly modified) A15 core, and the Exynos 5xxx uses a fairly stock A15 core. So a higher clocked A15 should beat out a lower clocked A15 in a direct comparison no matter what. Then when you throw 2 additional cores on top it should always win in multithreaded benchmarks too. Seems pretty common sense to me.
The main difference will be in the graphics side of things, where Nvidia has their own designed GPU compared to Samsung's use of the Mali GPU's.
You can still compare them together just fine, it just need to be both of them on the same browser if there is a browser comparison being done. In this PR release, Nvidia skewed the results like all companies do. So we cant really see the difference between the two from those pictures and we need to wait for 3rd party review sites to do proper testing to see actual results. Yet we can still estimate performance plenty fine since we have a baseline of the architecture already with this tablet.

"Tegra 4 more powerful than Nexus 10"... well duh! It's a new chip just unveiled by nvidia that won't show up in any on sale devices for at least a couple of months. Tablet and smartphone tech is moving very quickly at the moment, nvidia will hold the android performance crown for a couple of months and then someone (probably samsung or qualcomm) will come along with something even more powerful. Such is the nature of the tablet/smartphone market. People that hold off on buying because there is something better on the horizon will be waiting forever because there will always be a better device just a few months down the line!

That was kind of his point.
I don't think anyone is denying that the tegra will be faster. What's being disputed here is just how much faster it is. Personally, I don't think it'll be enough to notice in everyday use. Twice the cores does not automatically a faster CPU make, you need software that can properly take advantage and even then is not a huge plus in everyday tasks. Also, in the past Nvidia has made pretty crappy chips due to compromise. Good example being how the tegra 2 lacked neon support. The only concrete advantages I see are more cores and a higher clock rate.

Based on the hype : performance ratio of both Tegra 2 & 3 I wouldn't have high hopes until I see legit benchmark results.
What does seem promising though, is the fact that they are making more significant changes than from T2 to T3, such as dual channel memory (finally after 1-2 years of all other SoCs having it -.-) and the GPU cores are different too.
Still, the GPU has always been the weakest point of Tegra, so I still don't think it can beat an overclocked T-604 by much, even though this time around they will not be the first ones to debut a next-gen SoC. Given the A15 architecture they can't really screw up the CPU even if they wanted to, so that should be significantly faster than the Exynos 5 Dual.
I've also just read this article on Anandtech about power consumption and the SoC in the Nexus 10 consumes multiple times as much power as other tablet chipsets, making me wonder how nVidia plans to solve the battery life issue with 2 times as many cores and a (seemingly) beefier GPU, not even mentioning implementation in phones..

Apparently this is the tablet that comes to take Nexus 10 spot, Vizio 10 inch tablet with Tegra 4, 2560 x 1600 resolution, 32gb storage, Android 4.2. And it should be coming out Q1 2013, I think this one makes me wait to hear some more about it until I buy the Nexus 10, although to be honest the brand is a bit of a let down for me.
Edit: the 10-inch model, key specs (aside from Tegra 4) include a 2,560 x 1,600 display, 32GB of on-board memory, NFC and dual 5MP / 1.3MP cameras.

BB AMOLED and Exynos :(

Sad news...
Yes you just read the title of this message right. Our insider just gave us the first official “unconfirmed” specifications of the next generation Galaxy S, the Galaxy S IV. The Galaxy S IV will no longer use the Samsung EXYNOS processor and according to the latest rumours this processor has overheating issues. Today we can confirm Samsung will use the Snapdragon 600 and it is clocked at 1.9 Ghz which is 0.2 Ghz higher than the HTC One. The Galaxy S IV will have 2 GB of RAM and will come in three variants 16, 32 or 64 GB. As the rumours earlier reported Samsung is going to use a Full HD display. The Galaxy S IV uses a 4,99″ Full-HD SoLux Display we have no information if this is based on LCD3 like the HTC One. But a couple of months ago we posted the first hint regarding Samsung’s LCD factory is ready to produce Full HD panels from early 2013. And we also know Samsung’s AMOLED factory does have many problems with the production of full HD AMOLED screens.
We also know more about the build and dimensions of the device. According to our insider the dimensions of the device are 140.1 x 71.8 x 7.7mm and the weight is 138 gram, the new Galaxy S IV will use a home button and will have touch buttons. If you look at the photo below you will see that it will be square formed again, so they dropped the Galaxy SIII design line. He also said the sides are made from aluminium but the back is still plastic which automatic hints to a removable battery which is good to know.
Yesterday we already found out that the Galaxy S IV will have a 13 megapixel camera. Some leaked photos created by the Galaxy S IV showed up to confirm that.
If our insider is right again this is a bad sign for all the EXYNOS and AMOLED freaks out there. Below a list of the confirmed specifications through us right under the specification list you will see the boot screen photo.
- 4,99″ Full-HD SoLux Display
- Snapdragon 600 1.9 Ghz
- 2 GB RAM
- 16, 32 or 64 GB
- 13 Megapixel
- 140.1 x 71.8 x 7.7mm
- 138 gram
- Home button with touch buttons
- Plastic back with aluminium sides
- Removable battery
- Black / White

Exynos 5 Octa uses I think it was 4 low power cores and 4 high speed cores, so it's not a battery drain for low end tasks. (Octa = 8)
I will wait for official word on this, I can't see Samsung announcing the Octa this year, then not using it, it gives competitors a chance to trump it.
If they do use the snapdragon 600 it will be good because whist yes the Exynos is a good processor Samsung will not release decent documentation for it, so developers have a hard time getting AOSP roms working efficiantly, the Snapdragon range is completely open source so roms will work a lot better, and be easier to port. Exynos has already made developers leave Samsung devices.

doubt that, since they got LTE and exynos working together finally. but the snapdragon seems like a give and take situation. that octa looks like it'll be an amazing processor, but if it's a snapdragon then we can finally get AOSP working fine.
as for the LCD, that's gonna be a personal preference for everyone. I wouldn't mind either, but I'd miss the blacks on the LED. the color punch is really nothing, I set my display to natural.
but really, do we even need the octa now? these phones we have now are over powered. I run my note ii at 1ghz with 1 core enabled and notice no differences in day to day use (except video chatting, that requires at least two cores lol) . point is, these quad cores (by today's standards) are just too much, and kinda gimmicky. I don't think we'll need to see the octa for a good year or two.

Samsung have announced the Octa now, it won't be long before other chip manufacturers try to beat it, then Samsung's great idea will be old tech before it comes out. They have no choice but to put it in something if they want to make any use of it.

Btw we will get more details from Samsung on mwc starting tomorrow. Ill believe this only if it comes from Samsung. Whatever the processor or screen it has already been decided and s4 shoukd be in mass production right now.
《posted from s3》

I think that's nt true. Because making a SS on PS and open up that image on a phone and taking a photo in bad light conditions isn't too hard.
Actually, I think that phone is Xperia Z or LG Optimus and photo taken with a S3...
Next Galaxy S device(international version) will have Exynos Octa(5440 or 5410) or Dual(5250) with 5" FULL HD Super AMOLED Display. Why Samsung use another solution? I don't know any logical reason. Warming? Power consumption? Software based reasons? I don't think so. This is my two cents.
On the other hand, I think(I know, I used a lot -I Think-s)next Galaxy S device will have Exynos Octa, 2GB of ram, Mali T604 or T658 GPU, better camera lens(S3's sensor is good but lens is a bit deficient.), 2600mAh battery and also more durable chasis and screen. On software, Samsung will do wonders...
Edit: If I had gramatical mistakes, I want to say I'm sorry for that. Because Eng. is my 3rd language.

You obviously seem to have very little knowledge concerning technical product design. If it' physically impossible at the moment to manage the heating problems in this case, then in fact THIS IS a reason to kick the Octa processor for a Snapdragon...
