Is safe to downgrade my S21 ultra software from android 12 to 11?

Since I have updated the software my phone keeps crashing alot and freezing. Had major problem with the phone randomly restarting it self alot. Just wondering weather if downgraded the phone to android 11 would fix theses problems? I only started have theses problems when updated to android 12.

I have s21 ultra

Downgrading is very difficult and not recommended.

When did you last perform a Wipe Partition Cache on your device?

1. Turn off the device.
2. Connect To Computer USBC to USBC (you may also connect to another Samsung mobile via USBC). Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

I've tried this method couple times but doesn't seem to fix anything for me but thanks for the advice.

Have you tried factory resetting the phone? Set it upbas a new phone and only copy back documents and media. Download apps from Play/Galaxy Stores as required.

That's a bummer! If Samsung Experience Store is near by, may be you could let them have a look at the issue or book for a repair (pick up).
