I have been experiencing issues on my Samsung S21 since upgrading to Android 12. The phone app lags when calling and waiting for the sim selection pop up. Apps are also crashing since the upgrade.

I'm from South Africa and have already done the second software update for Android 12.

Check your apps are upto date

I have the same issues. Especially on Google maps and mail. It's very frustrating. I've cleared cache partition and resetted numerous times. I hope there will be a third update
