Hey @JTidd, are you still having issues with this? Does it happen when using the embedded Camera app? If so, make sure that the software of your S20 Ultra is up to date by heading to: Settings > Software Update > Download and install. Next, follow these steps to clear the cache: Settings > Apps > 3 dots (top-right) > Show System Apps > Camera > Storage > Clear cache and restart your phone, leaving the device completely off for 3-5 minutes before turning it back on. Then try the camera again.
Thanks for giving that a try. Please use the camera while the phone is in Safe Mode. This will disable all third-party applications temporarily, to see if they are the root cause of the issues you’re having. To do this turn your phone off, then back on, and when you spot the Samsung logo on the screen, press and hold the Volume Down button until you see displayed ‘Safe Mode’. If the issue disappears in Safe Mode, you’ll need to disable the third-party apps one by one until you find the culprit. To exit Safe Mode, simply restart the phone.
@JTidd: No problem. 'Action Required' does suggest that there is an issue with the hardware, therefore an engineers inspection would be the best course of action.
