I did a clean install and the phone runs perfectly. Battery is ok but I feel it could be better. Was way better in Feb but can't remember the update. I was getting almost 3 days light usage. The April patch just browsing the web and apps would make the phone warm. Since the may update it's never heated up, not even slightly
Are you using 60 or 120hz? I think Februar Update had the best battery life but the phone got really hot while using the camera. May Update fixed the heating while using the camera.

Hey y'all,

XSA ROM here (S21U Exynos) and just Odin flashed DBT AUDA (24 hours ago).

Haven't noticed anything negative. At least nothing significant enough for me to notice...

Cleaed cache following the update and re-ran App Booster, for whatever it's worth.

I'm not anal about battery life but I haven't noticed any significant drains after the update.

So for me, it's been kinda; meh... :-D

I have a SD888 version since launch. There is a constant heating issue, and most noticeable the first time you use the phone when you wake up. Looks like it was fixed in the April update, but now it's definitely back in the May update.

Samsung Galaxy S21 Ultra
I guess in India as well the update ( auda) was released as an ota .

I did a clean install via odin .

I guess they pulled it from other countries.

I hope the new update fix the scrolling lags some users are experiencing

    You can post what you feel about the update here .

    For me

    1) qr code in camera app is way faster
    2) camera doesnt heat up the phone now
    3) gaming also runs cooler
    4) animations are better
    5) expect an sot of 1h more than you got with april update.

    Looking for more changes ..

    Tell me in comment .

    I think samsung is doing a great job ,
    I was about to trade off my s21 ultra with mi 11 ultra , but this update has stopped me doing so.
    Nice! Very much looking forward to getting the update now.

    Photo processing seems better too.

    Look at this photo I took today. It's sharp, detailed and HDR is awesome.
    Excellent edge detection in portrait.
    Animations much much smoother.
    Battery life is better.
    Good job Samsung with this update.

    Flashed it via odin, then cleaned cache partition.
    Patiently waiting here in UK too...
    That looks great, really sharp image. Are you on Exynos? I've seen some videos where the screen animations look smoother too.
    Yeah it's really sharp. Yes S21 Ultra Exynos. The device is really smooth
