Aakash Kindly check ur facts ..
I9100 is now getting replaced by I9100G in India and some Asian countries. Its important to know the differences:
[font=tahoma, verdana, arial, sans-serif]1. I9100 has better CPU and better GPU compared to G version. G version's CPU is capped at 1008 Mhz, it seldom reaches the specified 1200 Mhz when in stress. The Mali 400 in I9100 is much better than PowerVR 540 in I9100G (this same powerVR 540 is present in Galaxy Nexus, Moto Razr, Optimus 3D etc)[/font]
[font=tahoma, verdana, arial, sans-serif]2. I9100 has way better custom ROM support thanks to it being older and many devs have it. So all good roms like CheckROM, MIUI, Cyanogen mod are available. But, as the I9100G uses Ti OMAP 4430, which is very similar to Galaxy Nexus's Ti OMAP 4460, and as their GPU is same, expect ports of this mods for I9100G soon, as it will be more simpler to port them.[/font]
​Correction: Not necessarily, the most difficult part of cooking ROMS is the drivers. So until and unless devs have a driver set from a stock ROM they cant go to work. Just look at CM, they are building CM9 from scratch and they are having a hell of a time coming out with the final build. Until and unless u have samsung provided drivers cooking ROMS from scratch aint easy.
[font=tahoma, verdana, arial, sans-serif]3. I9100G, is having better battery backup and less heating thanks to lower clocked CPU.[/font]
Correction: I am on LA4 and I am getting more than 2 days of usage with moderate use. Heavy use reduces my battery life to around 1 day and 7-8 hrs.
[font=tahoma, verdana, arial, sans-serif]4. In Antutu benchmarks, when I9100G is overclocked to 1.2 Ghz, it actually beats I9100 by a couple of 100 points[/font]
Correction: with the recent firmwares (KK/KL/LA) benchmark scores have gone through the roof and the phone has become even more buttery smooth. So I take your statement with a bucket full of salt.
[font=tahoma, verdana, arial, sans-serif]5. There is no yellow screen problem, wake up lag, and color banding issue in I9100G, which are quite common in I9100 (google /youtube for these issues)[/font]
Correction: Subsequent batches of the I9100 dint have this issue, also those early adopters who did, their problem was fixed by upgrading to the later firmwares (KI/KK/KL etc). Color banding on gradients is there if u know how to look for it on all variety of SAMOLED displays and that includes 9100 and 9100G too.
[font=tahoma, verdana, arial, sans-serif]6. THE MOST IMPORTANT POINT: Samsung officially launched 2.3.6 Gingerbread for I9100G via KIES and OTA in INDIA. There is NO UPDATE released for I9100 in India. Its still stuck on 2.3.3 May 2011 firmware.[/font]
Correction: The GT-i9100 was updated to 2.3.6 (KL1) officially in november. Also rest assured it will get ICS earlier than the G too.
[font=tahoma, verdana, arial, sans-serif]This might not be a point of concern for power users who flash other countriy's firmware, but there have been cases of people losing IMEIs and their basebands while using other country's firmware[/font]
Correction: May Only happen if you are flashing custom ROM and dont know the proper way to flash. For flashing different region stock ROMS u dont need root and hence this issue will never happen.
[font=tahoma, verdana, arial, sans-serif]This has lead to an outcry from Indian I9100 owners, asking Samsung for I9100 2.3.6 firmware, but Samsung has not paid attention and they haven't even replied.[/font]
Correction: Samsung HAVE released 2.3.6 officially in INDIA
[font=tahoma, verdana, arial, sans-serif]So, if you want official updates, go for I9100G.[/font]
[font=tahoma, verdana, arial, sans-serif]Correction: Misleading statement.[/font]
[font=tahoma, verdana, arial, sans-serif]If you want custom ROM support and few 100 more numbers in benchmars, get I9100 [/font]
[font=tahoma, verdana, arial, sans-serif]That doesnt mean i am saying buy the I9100G if both are available if u can manage it get it perfect if not den I9100G wont give u any prob [/font]
[font=tahoma, verdana, arial, sans-serif]trust me [/font]
