It seems Samsung has started releasing Android 4.0.4 for Galaxy S II (I9100) users. Users in Russia can start updating the phone to the latest Ice Cream Sandwich OS via Kies. Although there aren’t many visual changes, XDA Forum users who flashed the firmware are reporting some additional Russian apps.
If you can’t wait for Kies, you can download and flash the LPM build with Odin.
I9100 users in other regions should get it in the coming weeks as well.
