    my phone goes on invalid sim card mode every now and then and the phone gets switched on and off automatically... sometimes it gets resolved when I switch off and put it on. the sim card has no issues as I'm using the same simcard in other phone. it basically started with Android 10 update.. please resolve this issue as it seems to be an software glitch or something.

    Do a Full Factory Reset

    This will restore you to a fresh installation of Android. So you will need to backup your phone.

    After Backing up the phone.

    Go to Settings,
    System,
    Reset Options,
    [e]26a0[/e]️Enable Erase Internal Storage[e]26a0[/e]️

    Then click on the Delete All Data button.
