Question: Sensor Issue --- The scree would not turn OFF during phone call .The screen display still ON during a phone call, and cause user easy to miss-touch the hook button to end the phone call accidently.

1. Some of mobile phone the proximity sensor only works when device is in vertical direction, but some phone’s proximity sensor works once user talking on the phone, no matter the phone is in vertical or horizontal direction.

2. Please make a phone call, then cover around the receiver with your hand (within 1 cm distance) to check the screen display has OFF normally.

3. If the screen still ON during the phone call, please send back for service repair.
