Recentely, I have used this intex aqua super it is good phone comes with 3GB RAM and 16GB internal memory. is has no lag or hanging problem I have seen in this phone sound quality isnt much good. Camera also is not better Front camera pictures is little blurry. And battery isnt good in this phones. And the display is better. It has no glass like Gorilla Glass or corning glass it has no safety of screen. Design is execellent I love the sleek design. It is on Android Lollipop 5.1 no upgradeble. Overall Good in this Price.
