New [mix2s-] Permission setting of some system apps resets to default after reboot


Aug 1, 2018
For example: The Gallery app has three permissions (storage, phone, contact) and by default they're all allowed. If I disable its phone or contact permission, it resets to allow after a reboot.
It seems that this issue only happens in some system apps.
This issue happens no matter MIUI Optimization is on or off.
On China ROM, if I disable MIUI Optimization, then I can disable Gallery's phone or contact permission and it won't reset after reboot.
