Samsung Galaxy I9100 vs I9100G Phone Comparison

Samsung Galaxy SIIUsing the credits of Galaxy S phone, the Galaxy S 2 handset no doubt is the top selling Android phone this year. It features a 4.3 inches Super AMOLED Plus touchscreen display along with 1.2 Ghz Exynos 4210 Soc and amazing 8 mega pixel camera. The phone was very sleek at 8.49 mm and there were 15 million happy customers who buyed this phone.

The Galaxy S II phone has been produced in various variants and one close enough variant of it is I9100G handset with just change in chipset. In this article we have gone through the comparison of Galaxy S II GT I 9100 official phone vs the Galaxy S II GT I9100G variant.


Galaxy S II GT I9100 – 1.2 Ghz Exynos SoC
Galaxy S II GT I9100G – 1.2 Ghz OMAP 4430 SoC

The official Galaxy S II phone came with Samsung’s Exynos processor clocked at 1.2 Ghz but the Galaxy S II GT I9100G variant comes with OMAP 4430 SoC with 1.2 Ghz clock speed. Its observed that the cpu speed is capped at maximum 1008 Mhz and never really runs on 1.2 Ghz even under heavy load.

Graphic Support

Galaxy S II GT I9100 – ARM Mali 400 MP GPU
Galaxy S II GT I9100G – PowerVR SGX 540 at 304 GPU

The S II GT I9100 phone comes with ARM Mali 400 MP GPU to provide graphical acceleration whereas Galaxy S II GT I9100G comes with PowerVR SGX 540 GPU running at 304 Mhz.

Battery Life

Both the phones go with same specifications in the battery makeup. The Galaxy S II GT I9100G phone comes with better battery than the normal Galaxy S II phone. This is due to heavy load and heating in Galaxy phone eats much of the battery. But without heating, the battery life will remain the same in both the phones.


I am not sure why was the Galaxy S II GT I9100G phone was developed with just changes in processor and graphical support but looking at the issues comparison, Galaxy GT I9100G phones performs better. The official Galaxy S II phone can heat up quite a lot of time under heavy usage and this thus reduces the battery life of the phone. Galaxy S II GT I9100G is with no such heating issues. Galaxy S II phone provides the best of the 3D performances and same as with the GT I 9100G variants does but it struggles under heavy load.

So looking at the issues of official Galaxy S II phone in comparison with Galaxy S II GT I9100G the latter one has better performance and battery life.

Developer Support & Update

The official Galaxy S II phone was so hit that it’s the best Android mobile phone every released and developers are constantly working for new firmwares, updates or any bug fixes. The case is not same with Galaxy S II GT I9100G which went unnoticed among the users and developers. So there are no consumers for latter device and even Samsung didn’t make much of advertisement of the this variant, thus hardly any developer supports it. Even the CyanogenMod provides no update to it and the feature of it looks bleak as well.


It’s reported that Samsung is duping consumers in many countries of Asia and other regions of the world by selling both the models with exactly the same packaging. There is no way to distinguish between I9100 handset and the I9100G handset until you check out the phone specifications by going through Settings > About phone. What more worst reported by users is that Samsung is selling Galaxy S II GT I9100G phone in the pack of Galaxy S II without distinguishing between the models. You may say there is not much difference between those two variants but getting the variant model would mean that you will be with no firmware update and no developer support.

    This would probably help someone wanting to buy a specific SII model, 9100/9100G.

    As per my OBSERVATION, here are the numbers that you would find on the box which would specify if it is a 9100 or a 9100G, without opening it.

    You’ll find any one of these numbers on the side of the box against the product code:



    Notice the “G” in the serial..

    Got this information from the contact us page of Samsung:

    Go to Contact Us-> Email.

    When it opens, select-
    Product group- Mobile phone
    Product type- Mobile phone
    Product subtype- Bar
    Scroll the model number now to find something like:
    GT-I9100 (GT-I9100LKAINU)
    GT-I9100G (GT-I9100RWGINU)

    I got a GT-I9100LKAINU from Pune & it WAS I9100 as expected. 🙂
    Go to the Samsung Smartphone showroom opposite Garware college in Pune, if you are here.

Also when conneted through USB it only charges the battery.I had tried several methods but unsuccesful. Now i have major problem to download files to PC, every time I have to remove memary card and connect to PC via external card reader. Also can not access phone memory via PC. I have also tried by Skies but it failed.

      Hi Mandar,

      This is problem with phone and not 2.3.6..

      Follow the below instructions, this will solve it:

      1) key in the dialer *#7284#
      2) it has 4 option there..



      3) For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. and then press back. try reconnecting… This works..

    3G speed in non G version is 21MBPS whereas in G version is only 7.2MBPS

    • Siddhant

      February 6, 2012 at 11:16 pm

      There is nothing like it 😛
      Both the versions have the same HSPA+ speed (21.2 MBPS)
      The only difference is of the manufacturers of the processor

      • pradeep

        February 22, 2012 at 5:26 pm

        i have checked it on flipkart where they are selling the g version and in the product specification it is written 3G: 7.2 mbps. so how come both version are having same speed.

    I’m sorry to say that, this update is rather SLOW and OLD as a G user. G variant has flood the market in Malaysia since September.

    Samsung has better technology but poor back up as compared to manufacturers of I-phone. There are different variants of TV out cable for handsets of Galaxy S series. I am struggling to get a TV out cable for my GS2 since months in Dubai without any success.

    • Able Lawrence

      March 26, 2012 at 8:12 pm

      Why do you need TV out at all?
      The part I enjoy best about sgs2 is the allshare DLNA and you can play your media files through Wifi network on your smart TV. I use sony TV and it works like they were made for each other
