It will download fine and on the install process when you get to the blue screen with the progress bar at about 30/40% it then displays an error. Then the phone reboots and once ready to use it shows an notification to contact Samsung service centre.
Is it possible it's only a certain device is the 5g model?
Maybe others can reply if experiencing the same issue and state the device used.
