Phone Will Not Update - Suggestions??
Hi everyone, dealing with an issue where my S21 + 5g will not update to a current version. I have an unlocked SM-G996U still running Android 12 on Tmo network. I know this phone is really old at this point, so I will be replacing in the next 6 months. However, I am unable to use many apps due to outdated software. I have tried using the OTA method as well as Smart Switch and neither will prompt the update. What else can I do?
