I'm always click on Software Update for my S21 Ultra since November 2022 & until January 2023 I still didn't recieve any update for it. Any answer?
Is your phone SEA set or imported from other region?
S21 should have recieved the one Ui5 update by now. But if it's an imported phone I'm not sure. But if it's the Malaysia set you should get the update by now!
Wait a few days, and you will get an update.
S21 series has already get the update in October 2022. Your phone should be imported set.
If so, does it capable to upgrade to android 13
