I would certainly put 5 star rating as if a little mishap had not made me understand that there is another problem elsewhere.
One day, two months after my purchase, I left Jack 3.5 only works for one headset. So I contact the service department asking me to send him the phone, that I do not wait.
The repair takes several weeks, and finally I get my phone with a document indicated that the anomaly has been detected and repaired. I turn on my phone, and then redo the configuration surprise .... The problem has not been fixed.
I recontacted the service but they still invite me to return my phone. Finally I think I'll buy a Bluetooth headset because I do not want to be disappointed again.
