I bought this phone an year ago and this phone is not as good as I thought it could be. This phone lags a lot Sony needs to do something about this as it has only 1 GB of ram. It has full HD display but its not okay to buy this phone. The design of this phone is also very good like any other Sony phone.
The sound I think is a bit low as compared to other phones. Even the features is very less as compared to others. The camera performance is a bit ok I guess as expected from sony.
The only thing is high is the money. Sony needs to bulk up their phones not in terms of price but also in performance and features.
