Samsung Galaxy S3 Android 4.3 update is one of the worst, if not the worst, firmware updates in the history of all Androids. The official Android 4.3 update is filled with so many bugs and suffers from such poor battery life that the current S3 owners are forced to look for a new device whereas the other minority are still looking forward to the official 4.4 KitKat update rollout.
There is still no official word from Samsung about their plans on delivering the 4.4 KitKat update to the affected Galaxy S3 users and if the Android 4.3 update was any indicator, S3 users are probably in for months of wait. In other words, if you are also among those million of unfortunate Samsung Galaxy S3 owners who are currently on the buggy Android 4.3 mess which Samsung calls an OTA update, then you are simply on your own for now.
However, luckily the folks over at OmniROM have released a ROM based on Android 4.4 KitKat which is specifically designed for Galaxy S3 handsets. Unlike the stock ROM which is filled with RAM hungry bloatware, OmniROM’s version of Android 4.4 KitKat offers a much cleaner UI and an almost Vanilla Android experience. There is a known bug within this ROM which affects S3′s camera and video playback, but considering the state in which these devices are in right now, this camera bug is nothing.
1. OmniROM has released this KitKat ROM only for the folks the international version of Samsung Galaxy S3 only(GT-i9300). In other words, if you happen to have an AT&T, Verizon, Sprint or any other carrier branded S3 handset, well then you are simply out of luck.
2. Before beginning with the procedure, your Galaxy S3 should already be rooted and have ClockworkMod Touch 6.0.32 installed.
3. Make sure that USB debugging is enabled on your device and that your computer is equipped with the latest USB drivers. Also a minimum of 40% battery is recommended in order to prevent any unexpected shutdowns.
Step 1: Download OmniROM 4.4.2 and Gapps on your computer from here and here, respectively.
Step 2: Now copy the files downloaded in the first step and then paste them on the root folder of your Galaxy S3. Make sure that you don’t extract the zip files.
Step 3: Disconnect your device and then switch it off. Now boot your Samsung Galaxy S3 into recovery mode by pressing and holding ‘Volume up + Home + Power’ keys simultaneously until a familiar logo appears on the screen.
Step 4: Create a backup of the current ROM which your Samsung Galaxy S3 is running on by selecting ‘backup and restore > backup’.
Step 5: Now install the OmniROM 4.4.2 ROM downloaded in the first step by selecting ‘install zip from SD card > choose zip from SD card > select OmniROM 4.4 > confirm installation.’ Repeat the same step for installing Gapps.
Step 6: Select ‘wipe data/factory reset’ in the main menu to wipe all the data.
Step 7: Now reboot your Samsung Galaxy S3 and wait for a few minutes till the new 4.4.2 OmniROM installs on your device.
Step 8: Enjoy the goodness of KitKat months ago before Samsung actually releases an OTA update for your Galaxy S3.
