Which apps still need to be updated (with the above stuff):

- Email
- Private Share
- Good Lock and modules

Not much work to do by now

Anyone noticed huge Google play services battery drain on BUKG? After the update it seems to be on the top 2 drainers with more than 10% daily drain.
I just noticed that my battery drain is more fast respect One Ui 3.1.

But I have no idea of which cause that.

In every case it shouldn't be long before Samsung releases the December patches (hopefully with fixes for battery consumption and system fluency).

1. My AA is working great. Sure I have the occasional connection issues where I just need reinsert the cable - but that's just AA. Can't blame google completely - Car Manufacturer + Samsung are to blame too. And the cable..
2. No Idea. I see 3 dex app packages on my phone - a total of 7.5 MB. Not taking up space, so doesn't bother me. Dex can be handy at times. Just disable dex?
Thanks...I think I had to restart the car and the device to get AA to work properly...all's well so far.

Do you have any google account syncing? How about Google discover and the google app? Are these running too? Here's what I did...I uninstalled the google app, stopped my google account from syncing (using Samsung email for email, and Samsung cloud for contacts sync), and chose Samsung Free for the left screen...After doing this, google play services is far well behaved...

Both: one Google account and Google app (with every permission disabled. I don't want to uninstall it, because could generate FC on launcher).

How about stopping google sync? I'm sure that will reduce the play services drain...
I can't disable sync, without disable it on every account.

At the end every solution it's a palliative. Better to wait the December update, I don't think much time is missing before the release.

Hope everyone is well,

Has anyone experienced any WiFi issues?
Mine keeps disconnecting or connected without internet.
It connects to the network and within a minute or two it drops and says no internet and goes to 5g.
All other devices at mine are connecting fine.

I've tried factory reset, tried resetting network, cleared cache, disabled switch to data in WiFi>advance, still no joy.
only started after BUKG update

Any ideas?

Sell your S21/S21+/S21U and get the note 9 if you want great battery life 🤣🤣 2 days usage and 6 hour screen time. I could never get that on my S21U. Maybe back in march when battery was good, but it looks like Samsung are going backwards
I'm really considering going back to my p40 pro which is patiently waiting for me in a drawer 🤣

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

    @joloxx9joloxx9 & @adamlee2012

    Good day to you both. Just dropped in for a bit of thread cleaning and a friendly request. Both of you have been excellent and helpful members on XDA for many years now, and for that we are grateful. Having said that, I am politely asking both of you to please end this pointless feud here and now on the public forums. If you wish to malign and prod each other, please do so via PM's since this is not Mega, IG, Twitter or whatever other site you choose to use.

    Please keep this thread on topic, and do not detract further from information that other members are asking and posting about.
    I greatly appreciate your cooperation, and wish everyone a pleasant day. Now back to your normally scheduled programming. (y) :cool:

    Yep your right, im past caring. Might give one plus a go.

    If you want to, that's fine.

    But SPOILER ALERT : you're gonna find issues, if you look for them.

    That's what I'm trying to make you people understand, you overthink all of this. Just use your phone and wait for the devs to update.

    I was just like you, but today I've past this obsession of the efficiency. You are wasting too much time trying to mesure and compare.

    But that's your time, use it the way you want ;-).

    Happy new year everyone!! 🎆🎆🎆

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S21 Ultra 5G!
    NO CUSTOM ROM's and/or ROOT-talk

    How to flash the firmware to your phone:

    Odin.png


    1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
    2. Download Odin v3.14.4
    3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
    4. Open Odin
    5. Power OFF your S21 Ultra 5G
    6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
    7. Wait until you get a blue sign in Odin
    8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
    10. Click the start button, sit back and wait few minutes for the device to automatically restart.

    *** You can always find the LATEST firmware in message #2

    I have taken over these threads and they are dedicated to the memory of Henk, you can read more about him here:

    Thread cleaned. Just a friendly reminder to all. While a certain amount of OT discussion is usually always allowed on XDA, that does not condone starting a flame war based on one's
    opinion over another's. So please be respectful to each other, and please keep OT discussion equally respectful. Remember: "If You Can’t Say Something Nice, Don’t Say Anything at All." Is still a good rule to follow. Thank you for your cooperation, and a pleasant day to all.
