Please upvote the issue by clicking the '+1' icon on the IssueTracker page. DO NOT leave a +1 comment - use the +1 button in the top right of the page next to the "Hotlists" field.  Leaving +1 comment spam makes it impossible for developers to engage in the necessary technical discussion to implement this fix, and will disincentivize the responsible Google developers from engaging.  I don't know a fix for Android versions <13 either. So, this needs a phone running A13+.

 > There are **no exceptions** to the root requirement until Google/your OEM figures out a fix.
