Few months ago my samsung core mobile fell in water and didn’t start.So decided to take new one.Oppo was new in market so decided to take that one only.Took neo 7 at 8, 500 .The sound quality was good at starting but now getting lower.It heats alot after playing games for just 10 mins.The design is pretty good. But what to do with design if it’s not working good? .Its better to buy other mobile at this price as this mobile is not worth 8, 500.as per me.
