Hi, @ZahidB. It's definitely unusual that your S22 is ringing for no reason whatsoever, so I'd recommend looking at what could be causing this and then following some steps to resolve this.
Firstly, I think it would be worthwhile to start your phone in Safe Mode to see if the phone still rings in that state:

If the issue is not evident whilst in Safe Mode, then it suggests that it is being caused by a third-party app. You can then identify this and uninstall it.
Other steps that are worth following include clearing the cache on your S22:

Additionally, the following thread is likely to prove helpful here too:

Please let us know when you get this resolved and which particular step enabled you to put an end to the unexpected ringing on your phone.
