The alleged leaked ROM will be based on the Android 4.2.2 Jelly Bean operating system, where it sports a built date of July 24. The thing is, there is no change log available for us to refer to at the moment, and neither has there been a list of the particular issues, should there be any, to watch out for. However, early adopters of this leaked ROM did mention a launcher, weather widget and lock screen that hails from the Samsung Galaxy S4, in addition to a performance that is a wee bit smoother than usual. Too bad there is no support for the coveted multi-window feature for Samsung Galaxy S2 Plus users. The official update should arrive soon in Germany first, before selected regions around the world get hold of it.
