I m using this phone last 3yeats mobile is good almost no hang problem nice camera but battery back up not so good.call quality sound and picture quality too good.strong mobile so many times it has fallen but nothing injured it.mobile built quality nice .minimum hang lags. I think lava should revise this phone with stronger battery backup and larger internal memory space and ofcourse with larger external memory segment such as 128 ya 256gb memory .good pricing .this indian company performing well indian should encourage this pure indian product.pros: nice camera minimum hang nice strong built quality good resolution cons: battery back up.hope lava will go through my review and improve .best of luck guys
