Subject: [PATCH] prevent overlays on the phone settings
|
|
|
|
A report came in showing a 3rd party app could overlay a button
|
|
on the phone settings causing unwanted behavior. In order to prevent
|
|
this, a new system flag has been added that only allows system overlays.
|
|
|
|
bug: 246933785
|
|
Test: manual
