My Galaxy S20 Ultra 5G camera works for a second, sometimes long enough to actually take a picture that saves to gallery... Then it's "camera failed." I'm like "WTF"...?
Failed when checked after each of the following steps:
1. Cleared cache, etc. Reset app settings.
2. Tested in safe mode.
3. Completed factory reset without restoring custom backups.
4. Tested in safe mode.
4. Uninstalled all automatically installed apps wherever possible.
5. Disabling and force stopping apps wherever I can. Then I'm periodically testing the camera until I work through every app.
Most expensive phone I've ever purchased.
I'm pretty annoyed and disappointed right now. Grrr.
From the troubleshooting you've already tried I'd suggest to visit a Samsung Experience Store or Samsung Service Centre for support @Lesarh
I wish you all the best.
