How to Fix “iPhone Keeps Going to Lock Screen” Bug
This issue happens while using an app; users’ screens go black, show a spinning wheel at the center, and then revert to the Lock screen. So why do these iPhones keep locking? Many users on the reddit forum, where this solution originated, have noted that deleting the app Headspace and restarting the phone has solved their issue immediately. However if you don’t have the Headspace app and are still having the issue, or you’d rather not delete that app, we have a solution for you as well. Here’s how to fix the “iPhone Keeps Going to Lock Screen” bug.
First, you need to turn off all Notifications. In order to do this:
- Open the Settings app.
- Select Notifications.
- Tap the arrow by each app.
- Toggle off Allow Notifications for every single app.
Next, you need to update to the latest iOS or iPadOS. Once your device has fully installed and downloaded the iPad or iPhone software update, you can go through and turn on notifications for the apps you would like to receive notifications from; although, if Headspace is one of those apps, I recommend leaving it off for now.
YouTuber tipswithpunch has noted that after going through this process, your iPhone may go to Lock screen by itself once more but, after that, it should be okay.
If the problem persists, contact Apple Support. You may also try reading through the epic reddit forum to see if there’s a solution someone else mentioned that might work for you.
