It is to be remembered that Android 4.2.2 is the latest version of Android operating system and many high end phones are yet to get the version.
Meanwhile, SamMobile has claimed to have received an official test ROM based on Android 4.2.2 for the Galaxy Grand Duos. Now if there is a test ROM, there will obviously be a final one which will be pushed as update. However, the report does not talk about any deadline.
The Android 4.2.2 update is also likely to be released for Galaxy S III, Note II and a couple of Samsung's tablets. Samsung Galaxy Grand Duos GT-I9082 features a 5 inch TFT LCD WVGA (480×800) resolution display, a 8 megapixel camera and a 1.2 GHz processor.
With the new update there will be new features like transparent notification bar, Smart Stay, Light effect by unlocking, Page Buddy and Day dream.
SamMobile says that the device itself feels pretty fast compared with Android 4.1.2 and the battery life seems to be improved. There is no new feature in the update for the camera though, the report further claimed.
