This morning i got the one ui 4.0 beta of the note 20 ultra . I changed my csc to the US one . The update feels very stable . The battery has been better the on Android 11 . Just talking about the 7hrs I've had this , the battery seems better. Only thing is some apps are still not updated to one ui 4 (like home up in good lock and sound assistant) .
I'm sure they will release an stable version soon.
Hi I do have a question that you have canadian Note 20 Ultra then how did you change the model number to get the update? Canadian model number ending with "W" and States have "U".
I flashed it with an unlocked US firmware. You can download any of the note 20 ultra firmware from the US CSC will be XAA for the unlocked. Sometimes the carrier-branded firmware doesn't get beta .
