Hi @SwanseaJack1 ,
it's hard to say without hands on your S20 series phone. Do you have the Camera set to open when you tap a particular button? If so, they may have activated this. You can check this from the phone Settings> Advanced features> Side key> Quick launch camera.
Thanks for checking this @SwanseaJack1,. Would you be able to monitor this and see if that happens again, if it does, I would recommend sending our engineers and Error Report so they can find why is this happening.
To do this head to the Samsung Members app> Get help> Error reports (please make sure to replicate the issue then file the report within 5-10minutes of the issue occurring, please provide a timestamp if possible).
Once here toggle on 'Send system log data' (if not already toggled on), you will notice a notification at the top that indicates logs are being captured, this means any issues occurring in the background of the software our engineers can locate these and let us know the next steps.
Please allow time for this notification to change to indicate they have been captured. Now fill in your report, please include examples of the issue if possible by hitting the paper clip in the top right corner. Make sure to fill in as much detail as possible and send this off, we will then have our engineers check these over for you.
Please add any screenshots or screen recordings by hitting the paperclip in the top right, this can help them understand your issue further.
