The Galaxy Grand Duos was launched by Samsung to provide a cheaper alternative for those who wish to own a smartphone with big display at economic price. Since the company wanted to target consumers in Asian countries like India and China, it also comes with dual SIM support because people in these countries like to have such phones. The device is available in the market for quite a long time and was released with Android 4.1.1 out of the box.
Later it got Android 4.2.2 and now, when Samsung has already been rolling out Android 4.2.2 for a number of its devices, the Galaxy Grand Duos GT-I9082 has finally got a major software upgrade we were all waiting for a long time. Samsung had been working on the new firmware release since June 2013, and with the leak of the Android 4.2.2 Jelly Bean firmware for the phone back in early July, it was just a matter of time for the official roll out.
The Android 4.2.2 firmware update for the Galaxy Grand Duos GT-I9082 is available for the users of the device in 9 countries. Since all the firmwares, except one for Philippines, are unbranded, they can be installed on any Grand Duos that is not locked to a network carrier.
As expected from any major firmware update the Android 4.2.2 Jelly Bean firmware for the Galaxy Grand Duos brings a lot of new changes, features and some bug fixes. Some of the major features this new update comes with are as follows:
Saudi Arabia: KSA-I9082XXUBMHC-20130906143909.zip
