Well I bought this mobile 1 year back. It worked well for a couple of weeks and after that it has become worst nightmare for me. I thought it is a good mobile phone as it is samsung but no it proved to be worst. It lags alot everytime hang problem. I am suffering from that day till today. Sound quality is not as much of my expectations camera quality is ok. There are no parts available in the market for this mobile. Battery backup is very worst. I have to charge my mobile thrice a day. Now I think I must have bought xiaomi mobiles. Which are far times better from this third class samsung brand.
