A firmware for Samsung’s Galaxy Grand duos with Android 4.2.2 at core has leaked online and made its way to SamMobile.com. The firmware is a test build and not ready to daily consumption but adventurous users can certainly give it a try.
The new Galaxy Grand duos firmware packs several new features including transparent notification bar, Day Dream, Smart Stay, Page Buddy, and improved battery life.
There is no word on when the stable version of this update will be released for the smartphone but SamMobile notes that Samsung plans to release Android 4.2.2 for Grand, Galaxy S3 and Note II along with some tablets this quarter. Considering this quarter has just begun, you might have to wait for a month or two.
Here is a video and a few screenshots of Samsung Galaxy Grand duos running Android 4.2.2 leaked firmware:
