I received the notification for Beta 4 but when you check the downloads for the software update it's not there. Maybe its time to move on to the pixel 6 pro
You do realize that unlocking your T-Mobile S21 doesn't make it into the Unlocked variant? Both have different software and won't get the update at the same time.
LOL! Enjoy the 9 or so Galaxy Store app updates in the mean time. Usually when the GS has multiple Samsung app updates at the same time there's a system update coming very soon. I'm unlocked TMO too but device came from TMO so the firmware ain't unlocked. Even still TMO doesn't push the update to there entire network all at once. They do it by regions. Rollout literally like unrolling a mat on the ground. The mat doesn't touch the entire floor at one time. You'll be okay, I hope. LOL.
This is it this way. Look how many people can't afford such a luxurious device. It'll do everything except make you breakfast in bed. But I'm sure there's an app you can play and make virtual breakfast 😂:fork_and_knife_with_plate:️:cooking::bacon::bread:
That is a completely logical and accurate answer you were looking for. Chill out, you'll get the minor update soon. No need to be posting threads about something Samsung has no control over.
