Intex aqua serise is now running well.I think aqua shine 4G is the best among them.Sound quality is good.Speed of processor is also good.Fine battery backup with big display.Camery quality is a bit low but sufficient to use.flash light is very bright.I personaly prefer this intex aqua shine 4G mobile hand set.model is attractive.I will sugest this mobile phone ti buy and use.this phone do not get hot during charge.
