If they fixed short random lags during device use, would be great.
It's the only (and so annoying) bug left in the system.

You can no longer go back to Android 11, now and never. Rollback protection is irreversible.
you can go back to android 11, flash the latest version with odin... if you update to ui 4.1 ( hopefully februari) you cant go back to android 11....
This is not entirely correct. On BULF you are already on bootloader U4, so you can't go back to A11, if I have understood correctly.

I have lag after the BULF update. When I unlock the phone with my fingerprint and start scrolling sideways on the phone lags terribly as if it had a 10Hz refresh. Re-locking and unlocking help. I've never had anything like it. The best thing is that when I turn on the overlay that shows the screen refresh, it shows that it is 120 Hz and it jumps as if it was 10. It's the first issue after all upgrades for me. Samsung WTF 
It's because it's not refresh rate related. Until recently all phones had just 60 Hz screens but they used to have lags. Those screen had constant 60 Hz so how come they laggedI have lag after the BULF update.

? Because those lags are usually SOC related, ,kernel related problems. Hope they fix it for you all guys.

I have problems with lag on some apps. YouTube especially. It lags like crazy sometimes. Minimizing a playing video is janky af. The whole app feels like it's running on a 10 year old phone. It's not the app's fault! Tried on my old S10+ with Android 11. No problems there. So it is clearly Android 12.

I was really hoping this would help me. Tried for 3 days and there wasn't any noticeable difference with it on or off. I get the same 5-6 hours SOT on an average per charge. I'm not saying it doesn't help anyone else, it has obviously helped you. But with my use case, it's not making any difference

No it means the 2nd may update, as they have already received 1st may update and this is the 2nd update in May -
10@ EVERYBODY AROUND : ENOUGH OF OFF-TOPIC
If you pay attention, you'll notice that the thread is being heavily derived from its main topic which can result in a heavier cleaning if it continues that way.
PLEASE consider staying ON-TOPIC and let the XDA experience continue to be as joyful as it always was !
Thank you all for your collaboration.

Once again, we would like to remind everyone to remain on topic. While Android 13 will be a likely update, it is outside the topic of this thread, which is to discuss a specific update at a specific time. Remember, you can always create a new thread if you'd like to discuss something else.
Off topic posts will be removed, and infractions may be issued to members who continue to post them.65Man... after all these time and updates the device keeps lagging and the battery drain is horrible, I have to charge it in the middle of the day..I think this is my last Exynos device and samsung, I'll try to give apple a shot since my wife is using 13 pro max and she has 6 SOT at 60% battery which is crazy5

Greetings to all. Just dropped by for a little more "Unsubstantiated Update Claim Game" or UUCG for short, cleaning! Since this appears to be an ongoing matter, I will be happy to just drop by everyday and remove these little buggers with immediate effect in an effort to keep the thread on topic, which is why some of you reported these in the first place.
This way, it will eliminate the reports, and save our Mods, me in particular, extra typing practice, even though I need it!
Cheers to all: Badger50
15For the love of Pete!! Thread cleaned again!Can we PLEASE stop with all the unnecessary back-n-forth with these updates!!!! I keep getting reports from various members about constant OT, griping, whining, this that, he said this he said that, and disrespectful and snarky comments CRAP!! So from now on, if I have to action further reports from members that have been repeatedly warned, I will take up the issue with you regarding XDA Rule #2 for member conduct via PM, which can/may result in disciplinary actions regarding your account.
So Please, keep this thread "ON TOPIC" out of respect for the OP, and for all other XDA members. THANK YOU!!

I've cleaned this thread from all the off-topic posts and flamings; my cleaning included all timezone "discussions", not-firmware or S21U related posts, attempts to moderate the thread and much more. Actually, I must say I cleaned the thread AGAIN after all the attempts of my team mates @Badger50 and @V0latyle - and the expectations I'd to read here that the thread gets automatically cleaned e.g. in the morning simply shows disrespect to moderators by wasting their valuable time that could be much better used.
It finally got too much now! I've notified everybody whose post(s) got deleted i.e. everybody should be aware.
I'm requesting my team mates to inform me about anybody who still continues with this type of posting. In turn I'm going to revoke the members write permissions in this thread, initially temporarily for 2 weeks; however, the member will permanently have read permissions i.e. being inform of any firmwarm update. In case of recurring spamming, I'm gradually increasing the write ban to 4 weeks to eventually become permanently. I hope that this friendly warning helps to now keep the thread focussed. Thanks for your cooperation!
