Screen rotation

[t2sbx]

Hi I'm having problems with my phone screen rotation it's rotating in the opposite direction it should. How do I fix this problem.....I'm using a S21fe

Happens on all apps or just one particular app? if on a certain app then this is a software issue and can be fixed by removing that app. 

If not above, then the sensor is not working properly and visit Samsung for a solution.
