Why No 640x960 On Newer Model Phones? |

I was just comparing the specs on the new Samsung Galaxy S II versus the iPhone 4. One of the things that I was wondering about was the screen resolution on the iPhone 4 versus the GSII. Why did Samsung on this phone and other manufacturers with their latest releases not go for 640x960 resolution like Apple has done on the iPhone4?
Most of the latest releases seem to have 480x800 pixel resolution. Is this like the camera war that seems to have stopped at 12mp so that most will no longer fight for a higher density pixel amount and just stay at 480x960?
Thanks

Was wondering the same thing. 640x480 should be on 2.5" screens by now, and given that most phones are larger than the iPhone, they should all be sporting 1024x768 screens.

800x480/854x480 seems to be good enough upto 5inchs (Dell Streak) .Having had an iPhone4 next to my X10 i found it hard to spot the difference,and IMO 1208x768 would be over doing it on anything smaller than 5inch. The Moto Atrix comes with a 540x960 display: http://www.gsmarena.com/motorola_atrix-3709.php if you realy want a higher res than FWVGA.

Current resolutions in Arc/Neo/Pro/Play & S2 are good... higher resolution will surly increase the sharpness of images and the whole UI duo to the higher ppi but it will have negative impacts too
1- small difference in battery life... this is small enough to just ignore
2- lower performance in 3D games and UI rendering...
the iPhone 4 GPU it self ( SGX 535 ) is slower than the two GPU's used in the 5 phones I mentioned above ( all  uses Adreno 205, S2 uses Mali400 ), and it also uses higher resolution this is why 3D games dev. have to sacrifice quality to have playable fps...
currently the fastest GPU is SGX 540 ( used for example in OMAP 4430, in the heart of Optimus 3D )... and Tegra 2 which is a little bit slower than SGX 540.. and btw Tegra 2 by it self is a whole SoC and not just a GPU.. but it uses nV own GPU and no one else is using it.. and they cost more than Adreno 205 based SoC ( this what makes Adreno 205 more mainstream in the high-end )... but both of these GPU's are still not powerful enough to give 30 - 40 fps in high resolution like 960x640
so next year when the new or newer GPU's becomes mainstream and cost same as what todays Adreno 205, SGX 540 cost's then we may see higher resolution that can be used without sacrificing performance... but don't expect a direct jump between 854x480 to 960x640, there's a hell a lot of pixels there to compute  and screen panel makers tend to have a control hand here too... the close one is Atrix which has 960x540 ( 100px less in width than iPhone 4 ) and it uses Tegra 2... so you may have some nice performance if it was optimized to this... but just compare prices for Atrix and range

I think the current 480 x 800 is plenty for devices upto 5 inches |

I agree but I was just wondering how come no one else went as far as Apple did. Xajel did a great job in explaining the reasoning behind it.

The new Motorola Attrix has come close pixel wise. It will happen. I think with Android it maybe to do with apps I don't know
Phone?? What phone?? |

I think that's where should've made the difference with the gaming vs regular phones.
For those that want 3D gaming, standard res, GPU for higher framerates. Media/flagship should have = Retina display pixel density for photos, HD movies, browsing, etc.

With the advent of dual core chips I think it is now more than inevitable.
