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.

Same here!

Patrick, respectfully, a factory reset shouldn't be the fix.

I did a factory reset, even when I knew it wouldn't help.  It didn't fix anything nor would it BECAUSE we are now stuck with a different operating system.

Just after installing the update, my life became miserable. I could not use maps and hence could not go to my work shift where I regularly use the maps. I ordered something from DHL and it is in the packet station and I can not get the opening bar code because the DHL app is not working. If I don't get out in time, my friend is leaving to my home country in 3 days, I can not give him and hence I have to bear international shipment cost plus time. My emails are not working and I am having so much trouble with everything. According to Samsung, just factory reset the phone, how easy it is for them to say. Many apps are configured using PINS by post and it takes weeks to get back to the original condition as before. I am all the time thinking about the slavery of digital technologies. I have become a slave. My smart lights are not working so now I have to get up and switch them on or off. I am so confused about this all. I really wish to go old style, keep a small Nokia phone with buttons with a battery time of a week and make my life easier. I am just imaging the impact of one small software fault that has disrupted my life so much.

It is all very inconvenient indeed and in some cases these problems can have a huge impact as you have explained.

I noticed the DHL app not working as well today. It's not a solution but as a workaround i am using the edge browser and my DHL credentials to login to my DHL account and some other sites where the apps are not working either.

I hope it all works out for you and hopefully an update will follow soon.
A few other members have stated that a factory reset hasn't solved their problems.

In addition to my other reply.
I've noticed that some apps do work if you reopen them a second or third time.

I have the same issues after installing UI 4.0 on ultra.

Additional issues:
- Prime Video from Amazon crashes on start, reinstalling doesn't help

- videos sent (encoded) from Whatsapp have a green line on bottom and look like RGB channels are moved few pixels one from another - looks terrible

FIX FOR FACEBOOK APP LINKS: tap three bars on top-right, select settings and privacy, settings, multimedia, OPEN EXTERNAL LINKS (on boottom)

I'm samsung user since first Galaxy S and this was the sh*ttiest update ever.

Good to hear your feedback. Always good to share and hear what works and also what doesn't work so we can all get a better picture of what to do and why not to do. Thanks 😊

Thanks for the update, unfortunately i don't have that option in Facebook anymore. Couldn't find it on the website either.
I thought that was the problem too but they've seemed to have removed or moved the option for some.
