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 it gets heated like hell. Some said no sd card. Some said about camera quality. However, I took the risk and decided to buy it.
Now, I know I have made the right decision. 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.
