Samsung Galaxy S II Android 2.3.4 Gingerbread Firmware Leaks; Brings GTalk With Video-Calling Capability

In the world of Samsung based Android phones, firmware leaks are a very common sight. The Android 2.2 FroYo and the Android 2.3 Gingerbread firmware for Samsung phones like the Galaxy S, Galaxy Ace, Epic 4G and the Captivate leaked online, nearly a month before its official release. In fact, the Gingerbread update for the Ace, Epic 4G and the Captivate is yet to go online!

Now, it was only a matter of time before an Android 2.3.4 based firmware leaked online for Sammy’s latest flagship handset the Galaxy S II. Yesterday, a new firmware (KG1) for the Galaxy S II leaked online, and is based on Android 2.3.4.

Apart from a minor bump in the Android OS version, the firmware also includes GTalk with video chat capability. The leaked firmware also includes a new baseband/modem, which has definitely improved the network reception for me.


Many SGS2 owners expected that the Android 2.3.4 firmware will squash the high battery drain caused at idle, by the Android OS and the Android System process. Even though the drain caused by the Android OS/Android System process has gone down noticeably, they still drain quite a lot of battery.


SGS2 owners, who are interested in flashing this leaked ROM on their handset, can do so by following the instructions stated here. Keep in mind that flashing the de-odexed firmware will make the web browser slow and jerky.

    hey rajesh,

    you seem very tech savvy and enthusiastic..

    can you please confirm whether or not galaxy s2 camera sound can be muted (when phone is on silent) with the new update?

    there have been many many galaxy s2 users (such as myself) that dont want to void contract by rooting and would like to disable camera sounds to not disturb others..

    any information is much appreciated thx

    Android 2.3.4 is great. Surfing speed has improved noticably (a lot to me) and faster downloads which means they have put the words where the codings are. Website bug fixes are fixed for sure. I feel like using a new Galaxy S 2 really!! And we have not even come close to 4.0 icecream pie yet. Can not wait for the next firmware leaks! But there is one thing though, I can’t seem to restore the settings and datas back on to the phone from Kies. But it is a minor issue in exchange for what I have gained from this 2.3.4 upgrade
