SamMobile received by one of our insiders an official test ROM based on Android 4.2.2 for the Galaxy Grand DUOS. Galaxy S4 was the first Samsung device to run Android 4.2.2 out of the box but Samsung’s been busy updating older devices to Android 4.2.2. We don’t know the exact date or the devices that will get Android 4.2.2 but we expect it to be from this quarter for Galaxy S III, Galaxy Grand DUOS, Note II and a couple of tablets.
As said in the beginning, this update is for the Galaxy Grand DUOS GT-I9082 that features a 5â TFT LCD  WVGA (480Ã800) resolution display, a 8 megapixel camera and a 1.2GHz dual-core processor. The device came on Android 4.1.2 but with this Android 4.2.2 update that came from last month, you can expect some new features like transparent notification bar, Smart Stay, Light effect by unlocking, Page Buddy and Day dream. The device itself feels pretty fast compared with Android 4.1.2 and the battery life seems to be improved. Samsung didn’t update the camera with new features.
Below a couple of screenshots and a video of the Galaxy Grand DUOS based on Android 4.2.2. Our advice is to read the instructions before flashing!
