It's unbranded / unlocked
I've talked to the Samsung help desk, they couldnt help and were useless at communications. I wont be buying another Samsung phone after this one - I'll wait until the Pixel 4 drops and move on lol
I had a pop on my screen at 7am (UK time) to say that Beta2 was available and to Manually download it.
I have notuced that the battery is draining a heck of a lot quicker than normal since installing
