My S21 Ultra's main 1x camera appears to not focus when opening the camera app normally, however, if you give the phone a gentle bump/knock on its edge it seems to work fine.
If your Samsung Galaxy S21 Ultra's main 1x camera is having trouble focusing and requires a gentle bump or knock to function properly, there are a few troubleshooting steps you can try:
1. Restart Your Phone 2. Check for Software Updates 3. Clear Camera App Cache: Clear the cache and data of the camera app. This can sometimes resolve performance issues. To do this, go to Settings > Apps > Camera > Storage > Clear Cache/Clear Data. 4. Test in Safe Mode: Boot your phone into safe mode to determine if a third-party app is causing the issue. If the camera works fine in safe mode, then one of your installed apps may be the culprit. Uninstall recently installed apps one by one to identify the problematic app. 5. Reset Camera Settings: Open the camera app, go to Settings, and then tap Reset settings or Reset to default. This will reset the camera settings to their default values, which can sometimes resolve issues. 6. Physical Inspection: Check the camera lens and surrounding area for any dirt, dust, or debris that may be obstructing the lens or affecting the autofocus mechanism. Clean the lens carefully with a soft, dry cloth.
