Just I purchesed last month but now I facing lots of problem with this product the main thing is that battery performence is very poor in the time of data surffing it will take only an hour or less to fully drain also fully charging time is more than other products.Another problem is heating issue if you internet surffing for sometimes or playing games there will be heating problem.anther thing is customer care service is not up to the mark in case of any problem they will take much more time to rectify this.
