how to adjust iPhone 7 auto lock

How To Change Auto-Lock Settings iPhone X

It seems tgat when the last uodate was applied to changed the setting. The 39 second auto lock didn't start acting up till yesterday. It is very frustrating that the screen lick evey 30 seconds and we csn't change it because it's grayed out. I eill be calling Apple Care today to resolve this problem.

Not sure if you've resolved the issue, but I had the same problem until I found out my battery was on Low Power Mode in Battery settings.

When I turned it off, I was able to adjust the Auto-Lock settings in Display & Brightness

My Auto-Lock is greyed out and I cannot change the settings. It is currently set at 30 seconds and this is absolutely horrid when trying to run a business from your phone.

Hi

This setting has moved in iOS 10. Go to Settings > Display & Brightness > Auto-Lock.

Check your battery setting. It probably is on power saving mode . Turn that off and you can go back to the display and brightness section and adjust your timer.
