Many
iPhone X/7 and iPhone 6s plus user are facing issue after upgrade to iOS 11.4.1
and iOS 12 developer beta version that iphone proximity sensor too sensitive
after the iOS upgrade. The proximity sensor in iPhone is alongside the front
camera and its purpose is to turn or shut off the screen during a call when
user hold the phone near to his ear.
The
issue is that now iPhone screen turn off randomly while normal use likes
watching video or playing games or sometimes typing a message. Reason is iphone
screen goes black when covering sensor even while not on call. This seems to be
a bug in proximity sensor which is active all the times. The proximity sensor
on the iPhone top is very sensitive now, even with the shadow of hand is will
turn off the screen. Doesn’t matter which app is being used, the screen
blackout when held/handled around the top and upper edges. As soon as your fingers
move near the sensors the iPhone screen blacks out.
The
same issue was observed in iOS 11.3 where the proximity sensor became way too sensitive
however some user claimed that iOS 11.3.1 fix the issue but in iOS 11.4 the
issue reported again and proximity sensor remain active even not on call.
