The latest iteration of the Android OS, Android 4.3 has leaked and looks already there for the public, after previously seen running on the Samsung Galaxy S4 Google Edition. The latest Android OS is still not officially confirmed by Google itself but here it is still referred to as Jelly Bean, has been leaked to SamMobile, where it is described as functioning well without any significant obstacles.
Android 4.3 is available for the regular Samsung Galaxy S4 (GT-I9505), not the GT-I9505G variant and Google is selling directly to consumers starting this week. According to SamMobile – which has previously shared screenshots of Android 4.3 running on Google Edition – ROM has completely changed from how the source they provide, does not require modifications to work and is available on more common variants.
Of course, installing an unofficial ROM – even believed not to come from Google itself – will create and pose several dangers. The biggest problem is using an unofficial ROM will void your warranty.
