  1. Updated my LG G4 H810 from 10o to 20n a few days ago. I’m having these problems so far.

    1-No access to SECURITY features in SETTINGS
    2-No LOCK SCREEN set works

    3-Restarts the set when UNINSTALLING the apps

    4-Device heats up very often and battery timing isn’t as good as when it was on 10l version.

    Issue 1&2 fixed by installing Lock Screen App from Play store.
    Issue 3 not fixed even if I download the App uninstaller apps.
