Lock screen service bug
There are apps, which allow user to lock the screen with a press of a shortcut on a desktop, for example: One Click Lock Screen (can be found on Play store).
Once installed, the app requires lock screen service permission, after granting which the app successfully locks the screen, however, after reboot it doesn't work and when opened, redirects to the accessibility section in settings, as if the permission isn't granted, but in fact it is. After toggling the permission off and back to on, the app starts working again until next reboot. I tried with another app, and still getting same result. This is a Zenfone 6 firmware bug, I assume, since on my other phone with pure stock Android 10, it is working fine. Please, fix it.
