Based on the persistence of the problem, and the troubleshooting steps you have already attempted, please send an Error Report via the Samsung Members app, as this will allow us to take a deep dive into the software side of things.
To do this, please head to the Members app > Support > Send feedback > Error reports > Tap 'OK' to send System Log Data > Select the symptom, and include as much detail as possible.
