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.

Good evening,

Have you already tried a factory reset? Something could have gone wrong during the update. A factory reset will fix that.

Thanks for the tip but as i have read that many others with these problems have tried a factory reset without any success i wasn't planning on factory resetting my phone. Especially as a factory reset won't solve the problem of the phone switching between 60/120 hz resulting in a stuttery experience.

Issues that others experience is not important here. You presented an issue on this forum and I gave the best possible advice.

[sfritts]

And i appreciate your advice but respectfully refuse to factory reset my phone.

If Samsung comes out with a statement that a factory reset will solve the problems caused by UI 4.0 i will reset my phone but until then i refuse to be a test subject and try solutions that haven't helped others that experiencing exactly the same problems.

I've found multiple threads online regarding these problems with no solutions up to now. As i couldn't find one here my post is more to see if others are experiencing the same issues.

Hypothetically, what would you advise if i had already done a factory reset?

[Patrick]

I would say go to a service center to have new software installed. But thats not needed yet since a simple factory reset will most likely solve the issue.

[sfritts]

Let's agree to disagree

Same thing here. S21 Ultra via the official build update

[Patrick]

I gave the best possible advice, what you do with it is up to you.

[sfritts]

And thank you again. Even though we disagree i do appreciate your response and idea.

Unfortunately, I'm going to hold off with the most commonly advised solution after "have you tried turning it off and on again" until it has been further researched.

I have figured out that at least an older version of Outlook seems to work better but i did have to turn off auto update in the play store until the problem is resolved
