I too was doubtful as many of you people whether I should go for this phone or some other phone in the segment many people told its gets heated like hell some said no sd card some said about camera quality however l took the risk and decided to buy it now I know I have made the right desion after the update there is no heating effect I updated as soon as I received so I don’t know what would happen if you don’t update it’s an excellent slim phone don’t worry about anything you can buy it without any doubt I will give the rating 9/10
