Galaxy S21 Series@CarolB1: If the problem persists following the wiping of the cache partition, then the issue may be stemming from a third party app. What I'd recommend is checking the Settings > Display > Adaptive brightness after launching any third party apps you use regularly, to see if the feature is disabled. If you're able to identify the relevant app, head to Settings > Apps > Select the app > Change system settings > Allow permission, and toggle this option off. Let me know how you get on.
