Can’t lock iPhone screen

My iPhone XS is acting up and I’m not able to lock the screen with the side button.

When I restart the phone it works a few times but then it stops working again.

I read a tip to use the Assistive touch function, but it only works when the button still works. When the button stops working, so does assistive touch.


Any ideas what to do?

iPhone XS, iOS 13

Howdy Fnorf,


It’s great to have you in the Apple Support Communities! I gather that you are having issues locking your screen with the side button. I'm happy to help out with that. 


If you are currently using a case, cover or any other accessories, please remove those. 


Also, make sure you're using the latest version of iOS which would be iOS 13.5.1. This article will assist with updating if needed: Update your iPhone, iPad, or iPod touch


If the issue persists, try restoring to factory settings using iTunes. This process will erase your iPhone, fixing any software related issues.

How to back up your iPhone, iPad, and iPod touch

Restore your iPhone, iPad, or iPod to factory settings 


Then set up your iPhone as new and test while in factory settings.

Have a great rest of your day!
