Just two months I had the part in operation. Menu navigation, battery life, camera, operating speed - I was completely satisfied. Then it went one morning just no longer. Unfortunately, the phone service could not help me. Sent, the central repair service could not find the error - Two months Service-stress, then was reimbursed.
The crash of the device goodbye but both my sim had alsauch the memory card deleted - because the error could not be found, I was not ready to leave at this point send me a new device.
