Black screen during a call

為什麼我的Z5 Dual用任何通訊程式,使用直接通話屏幕就全黑:!就算致電中途仍未接通,手機完全離開耳朵或放在平面亦仍是全黑屏!




Why is my Z5 Dual using any communication program, using the direct call screen is all black:! Even if the call is still not connected, the phone will still be completely black after leaving the ear completely or on the plane!

However, when the call fails to be connected, or the call is completed, the mobile phone automatically stops calling or the other party receives the line, and the screen automatically lights up!

I don't know why! Please master the teaching!
