Samsung Galaxy DUOS is finally going to receive an official Android 4.2.2 update and possibly pushed at the same time with Galaxy S3 and Galaxy Note 8.0. It features new functions from Galaxy S3 and additions from the latest Android Jelly Bean OS.

Official Android 4.2.2 Firmware Testing for Galaxy Grand DUOS

SamMobile received a leak from one of their insiders about an official test ROM based on Android 4.2.2 Jelly Bean for the Samsung Galaxy Grand DUOS. The Android 4.2.2 early build features transparent notifications bar, Smart Stay, Light effect on unlocking the lock screen, Page Buddy and Day Dream.

Compared with the Android 4.1.2, the 1.2GHz dual-core processor and 5" screen display of the Galaxy Grand DUOS feels a lot faster and its battery life seems to have improved as well. However, the test ROM didn't have any updates for the camera app.

Release Date

Similar with Galaxy S3 and Galaxy Note 2, there is no specific date announced by Samsung when the Galaxy Grand DUOS will receive the official update. It is expected that any updates for the three smartphones are going to be released on the third quarter of 2013.

Owners of the Galaxy Grand DUOS may update their handset using the official ROM to enjoy all new features and improved overall performance.
