Hello @Averyheart ,
If you are observing a blank screen after launching camera, please navigate to settings > apps > camera > Permissions and ensure Camera, Microphone, Near by devices and Storage are enabled and turn off "Remove permission if app is unused".
If issue persists after enabling permissions, Please update Samsung members app to latest version from galaxy store and send us an error report immediately after experiencing the issue from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
