One UI 5 update on my Galaxy S21 is causing vibration every 10 minutes for no reason.

That's the whole story. Updated yesterday and now my phone vibrates every 10 minutes, day and night, with no associated notification. 

I downloaded Nice Catch to find out what was causing it, and that says Android System is what's setting off the vibrations. 

How do I make it stop? I've already silenced all notifications from all apps to make the phantom notification noises stop, now how do I make the random vibrations stop?

Hi, You could try the following options and see if it helps -

- Clear the cache in Settings > Apps > Android System > Storage > Clear cache. Restart your phone.

- Start your phone in recovery mode. Clear cache partition and in the same menu, there is also an option to repair apps.

Hi @Thecharmballoon 

Well that's certainly a conundrum your facing here.

May I suggest Safe Mode as a process of elimination.

> Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

If all else fails as a last resort consider backing up your phone and Factory Reset.

If I can be of any further help then please don't hesitate. Take care.  😎
