The update's build number is I9105PXXUBMG8, which is newer than the build that earlier leaked for the Grand. Android 4.2.2 brings new features such as lockscreen widgets, dedicated toggles menu in the status bar, improved task switching, Daydream screensaver mode, and performance enhancements. On the TouchWiz side of things, expect to see new widgets, homescreen and more from the Galaxy S4.
Here are the update details:
- Model Name: Galaxy Grand Duos
- Model Version: GT-I9082
- OS Version: Android 4.2.2 Jelly Bean
- Build Date: 29.07.2013
- PDA: I9082XXUBMGA
The update should be rolling out now but might take a few days to reach you. If you're unwilling to wait, you can grab the full firmware from the source link and update manually via Odin (you can flash it on a Galaxy Grand from any country, but you might have to wipe all data after a manual install to make it boot if you're flashing it on a device outside Russia).
