I was using Sony Xperia U before this and was so frustrated with the phone that I had decided to buy I Phone 5s (though it was out of my budget). Then some friends suggested me this phone. I was little apprehensive initially. But I was proven wrong. This phone works exceedingly in all aspects. Android version auto update makes this phone even better.
Performance is just awesome. No lags. No slowness. I am delighted.
