Samsung Galaxy Grand Duos has been a huge success for the brand because of its Note 2 like look and feel as well as interesting features at the budget price. The phone was release long back in December 2012 featuring a 5 inch TFT LCD display and other hardware specifications like its 1.2 GHz dual core processor with 1 GB RAM and runs on Android 4.1.2 Jelly Bean OS. Apart from this it has 8 GB internal storage and a supportive external storage Micro SD expandable to the limit of 64 GB. The screen resolution is 480 x 800 pixel and PPI of 187. Going towards the camera, the rear camera is of 8 MP and front camera of 2MP which suffice our need.
These features are quite large to meet the requirement of an average consumer for a mobile. The drawback that can be brought to your notice is the lack of future software upgradation. Although its been over a year, Galaxy Grand Duos is still running on Android 4.2.1 Jellybean and there doesn’t seems any sign of OTA firmware updates in near future because Samsung seems quite busy with updates for Note 3, S4, Note 2 and S3. And as we know Android has now reached upto version 4.2.2 Kitkat. Several devices already received the Kitkat update and many are scheduled, except Galaxy Grand Duos and others. But it can be sorted out by manually installing custom ROM based on Kitkat 4.4. I’m talking about Cyanogenmod 11 which is most stable ROM for your Galaxy Grand Duos based on Android 4.4 Kitkat.
