    Nothing happens when I press "sound and vibration" in the phone app settings,it only blink and I'm back in the phone app again without be able to do any settings.

    Someone knows what to do?

    It's not possible to uninstall and install the app again what I can see. The phone is not rooted, everything is "standard".
