I have purchased the smartphone one year ago. This smartphones operating system as well as its features are not good and I have bored with this smartphone. I really unsatisfied to operate this smartphone.at first its battery works good after a few days later the battery is going to dead immediately. Its processing system is also very poor as well as it's camera not captured any kind of photographs clearly. This phone often hanged then I restart it and its internal memory is very less. I have faced many kinds of problems with this smartphone. At last I want to say when you bye a smartphone you must think about it.
