I am not satisfied with this device, Device is keep restarting itself automatically, While we calling by mobile it introduces with microphone issues, Please tell me how can I fix this problem, Signal not working properly , Device is also does not working properly, Battery is draining to fast as compared with claimed by the service provider, While charger is plug in and keep in charging mode it start to heating badly, It very big issue with the charging and battery, I don’t know why the rating is high, I experience worst about this device, Except camera quality is totally waste of money
