I saw ia phone with my friend of intex which was working fine after 2months so I decided to buy intex aqua power .I faced same hanging and freezing problem. I am using this phone from last 1 months. I am using solo launcher and swift key keyboard.
Default keyboard is worst and default launcher is also worst. If I use default lock screen then there is no option to change its wallpaper. Not even on default launcher I can change the wallpaper of my home screen. All total I can say is bakwas.
