I updated my phone yesterday and since then my Quick panel buttons are gone, my phone keeps randomly restarting both in normal and safe modes and I sometimes get an error message regarding my update, see in pictures. What can I do???? Is this happening to anyone else???? Also, even though I am not in airplane mode, the airplane symbol will not go away. Plus my wallpaper picture disappeared and was replaced by stock samsung photo.
You can try clearing the cache partition which should be done after every update anyway. See if that helps. If it does not, your best option would be a factory reset. A factory reset gives you a clean operating system that was not overlaid/interlaced with the previous one. Restoring your backup is unlikely to replicate the error, as the OS is never stored with the backup.
