SCREEN ACTING UP
Screen does not turn on or off when it should
Cell phone screen does not turn “on” or “off” properly as it should.
The smartphone’s proximity sensor gets activated when the cell phone is placed near the ear
during a call in order to turn the screen “off” during length of the call to avoid user getting potentially
exposed to extra heat generated by a lit LCD screen.
This measure was also designed to prevent any phone tactile malfunctions that could be caused
by the ear rubbing against the screen. When the call has ended and the phone is taken away from
the face both screen and touch sensor are turned back on.
How to fix
1. When the screen turns on during a call or the screen does not turn back on after ending a call,
try cleaning the proximity sensor on the front freeing it from dirt.
2. Try to give it a good clean with a soft cloth.
※ Protective films and cell phone cases manufactured by third parties may also cause
the proximity sensor to malfunction.
