[S21] OneUI 4 / Android 12 Beta Mega Thread

[Rydah]

Howdy y'all, I hope you're all doing well.

If you're reading this, I think it's safe to say that your pretty darn excited for One UI 4 w/ Android 12! I'm so excited that we get to share the latest and greatest experience Samsung has to offer, together. With the One UI 4/Android 12 beta now rolling out, I want to hear what excites you the most from One UI 4 and what you'd like to see. What features would you like added?

The contents of this post serve as and provide valuable information for users looking to participate in the beta. This post will be frequently updated as new information emerges.

------- ☆ -------Beta Information

Some things to keep in mind before signing up and installing the beta:

• The main goal and purpose of the public beta is to gather feedback from users. When unexpected errors occur, please submit feedback via the Samsung Members app.
• The beta firmware is exactly what it is, beta. This means that there may be some unexpected bugs and possibly not so good battery life.
• Some apps might not function properly (if you rely on using banking apps, it might be wise to wait for the official update.)
• Data loss may occur. It is recommended to backup your data. Samsung offers SmartSwitch on both Android and on PC/Mac. I'd highly recommend making a backup of your data before you install the beta.

Hi all,

I've noticed too late that the beta does not support Google Pay.

I was trying to use the instruction to downgrade: I withdrew from the beta program in Members app and I was trying to downgrade my S21 through Smart Switch app.

Unfortunately, Smart Switch is downloading the files, but once it's trying to do the update it is stuck at 0%.

The phone gets to the flash mode, it says "Downloading", Smart Switch is at 0%. I left it yesterday for the whole night, but it did not move a bit.

Could you tell me what are the other options to downgrade to the official live OneUI 3 version? Or is there any trick to fix the Smart Switch downgrade?

Thanks in advance!

Raf

Hi,

First of all, thank you very much for this amazing post that explains step by step what needs to be done to both install and rollback of the beta programme.

I upgraded my S21 Ultra to One UI 4 last night but given some bugs I saw (specially around the Galaxy watch plugin constantly getting terminated in the background) I had to rollback today.

However, having successfully rolled back and, as far as I can see, withdrawn from the Beta Programme on the Samsung Members app, it still downloaded the ONE UI 4 and it is now expecting me to reinstall it. I don't understand why this has happened but haven't seem to have found anyone with the same issue as me.

Thanks!

Hi all. Can someone capture downgrade firmware from smart switch? I need it to use with Odin as I can not withdraw from beta because I've flashed it over Vodafone firmware without enrolling.
