I have a Samsung galaxy s20 FE that is running Android 12, and I need it to upgrade to 13. For some reason, going through settings/ about phone/ software update says it is up to date and doesn't give me the option to upgrade. Is there anything I need to do, or can-do to force the upgrade to android 13? Model number sm-g781u
