My note 20 ultra is a unlock version
Does not matter. Samsung is not a carrier. Carriers decide when the updates com through their network, despite whether it is an unlocked or carrier locked device. Several people will not buy unlocked devices because of how long it takes to get updates.
Finally, the phone is very hot to the touch!
All since going to Android 11 on my Note 20 Ultra 5G! The phone is worthless now! Avoid Android 11 at all costs!
