For some reason I didn't get the one ui 4.0 for my phone and I have been waiting too see if I would be able to get it？
Samsung post on members revealed the One UI 4.0 stable rollout schedule for its devices. As per the notice, One UI 4.0 based on Android 12 will start rolling out to the Galaxy S21 series this month, followed by the Galaxy Z Fold 3, Galaxy Z Flip 3, Galaxy Note 20 series, Galaxy S20 hence why I said it should be out now. I didnt see any information that shows If it's coming out in January or not. If you are aware of the exact push month then I guess you're might be right then.
Yes. This started about a Note 20 Ultra 5G not S21 or Fold. The same rollout schedule indicates a January release for Note 20.
