iPhone 8/Plus IPhone 8 Screen not going to sleep

[Qu1ckset]

I’ve noticed my iPhone 8 screen does not go to sleep unless I press the power/sleep button , in settings it’s supposed to go to sleep after 1min.

Has anyone figured out a fix for this issue ?

+1 on this issue. I usually do a soft reset when i notice it happening but it does seem to come back now and again

This happened to me too. Reset and it fixed it so far for me

Same here on my iPhone X — except mine will not go to sleep after a notification comes in, despite the fact that it’s set to auto lock after 30 seconds. That’s a big problem on a device with an OLED screen.

My sister has the 8+ and was having the same issue. I searched here and found this solution, which I can confirm resolved her issue. The steps was posted by Ladybug 10/13:

Someone posted this on Apple forums..might work for you too

1. Turn off passcode at Settings > Touch ID & Passcode > Turn Passcode Off.

2. Restart your device.

3. Turn on passcode at Settings > Touch ID & Passcode > Turn Passcode On. (Do not delete your saved finger prints.)



This worked for me. Auto Lock works once more.
