Problems after installing UI 4.0 / Android 12

[sfritts]

Problems after installing UI 4.0 on S21 Ultra:

- apps keep crashing. eg. Outlook, Google Search, Prime Video, etc.

- Facebooks works but i can't open posts.

- The entire system also runs very slow and stutters alot.

- battery seems to drain faster atm.

Tried solutions:

- Wiping app caches

- Wiping cach from maintenance mode

- Repairing apps from maintenace mode

- Reinstalling apps (also from Galaxy Store)

Installing Outlook from the Galaxy Store shortly solved the Outlook crash problem but it started crashing again after just one day of use.

I can't believe this build is called finished. This is clearly an unfinished product and these problems should have been solved in the beta.

@Samsung please fix! Phone is close to unusable.

Update: 3 dec. 2021

Installed the newest update ending with BUKG.

Unfortunately this did not solve my earlier problems.

I then tried all the above solutions again without success. 

As i wasn't expecting another new update from Samsung any time soon i had to try a factory reset.

Luckily the factory reset has solved most of the before mentioned problems. Even the installation of the OS itself seems to look different. 

I do believe that the factory reset in combination with the BUKG update solved the problem.

But the fact that a factory reset is necessary isn't a good situation and i hope less people have problems updating directly to the BUKG update instead of first receiving the BUK8.

Reinstalling and setting up all my apps takes hours of work and that doesn't even include the 2 factor authentication problems I'm running into with some apps and accounts.

I really hope that all remaining Samsung phones that our receiving the UI 4.0 update don't have these problems.

Let's hope the suffering of the S21 users has provided Samsung with enough data to iron out the kinks in upcoming updates😉 

Edit: some apps seems to crash in some instances. I believe this might be a problem with them not being fully compatible with Android 12 or UI4.0.

Update 7 dec 2021

Phone rebooted partially today. Didnt have to enter my pin but i did get a notice that my phone had restarted. 

Strangely enough this seems to have reset certain system settings to default. 

Eg. The touch vibration had been turned on again while i had this turned off and also certain keyboard options like auto replace were turned back on.

Eventhough most problems were solved with the install of the BUKG update and a factory reset not all problems seem to be solved.

I've sent an log through the Samsung members app.

I'm still setting up my phone but haven't run into those problems yet. The most problematic apps like facebook, outlook and my dhl were the ones i tested first and they work fine now.

I did just notice that Google Play seemed to be confused showing alot of updates but not doing anything. Cancelling the updates and searching again solved that problem.

Regarding the disappearing text, which keyboard are you using? I'm currently using the Samsung Keyboard but have used the Google keyboard in the past.

After the update and (unfortunately) a factory reset i also noticed that some app bugs seem to have been solved as well that were present before the update.

E.g. deleting an email in Outlook and closing the app before the undo message at the bottom had disappeared would result in de the email being restored to the inbox on the next startup of the app.

Reinstalling or resetting the app never never solved the problem before.
Glad this problem is solved now too but i hope a factory reset is the solution for every little bug.
