I don't really understand the separation of the list of countries. I am from Guatemala, could someone tell me if I can install it?

For me BUKG is amazingly smooth. It was a little laggy at first, but after a day it is fantastic. Just let the phone adapt to the new software and you will see very good results.

Starting to think it isn't a software issue. I can't stand to have this phone another 2 years! Stuck in a contract. I might have to try a battery replacement but that means sending my phone to Samsung and been without it for a week or 2
🤔😠😥

    BULF might be the worst one yet, previous versions had bugs and glitches but 120hz was always smooth for me, but now..

    On BULF it feels like the phone drops to 15hz, never mind 60hz, the slow down and stutter is ridiculous, completely lost the fluidity of my device.

    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

    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.
