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.
