So proud of this variant. No one has been whining and grinding their teeth about missing March update.

If anyone got the CHC update, let me know. it doesn't seem to be up in Sammobile.
[Samsung Galaxy S21 Ultra] mpore14:
Hey man, what's your SOT like when you have these on?

I seem to be getting 7 hours 100 to 0% which I'm not complaining but I feel like I was doing something wrong.
[Samsung Galaxy S21 Ultra] bodomfan:
8 hours but I have location,sync off, Bluetooth only on when needed
[Samsung Galaxy S21 Ultra] mpore14:
I see. I always have sync on and Bluetooth on that's probably why I'm less than that 🤔🤔
[Samsung Galaxy S21 Ultra] bodomfan:
Awaiting one ui 4.1
[Samsung Galaxy S21 Ultra] mpore14:
Some exynos versions getting it i think
[Samsung Galaxy S21 Ultra] Aboelnasr:
all versions have received the update as usual excluding our g9980 son of internet explorer
[Samsung Galaxy S21 Ultra] mapl.ph:
Hi All, I have a snapdragon 12/128 variant unlocked that came with SM-G998U firmware. I live in Philippines and will need the n78 5g band. I have already flashed SM-G998U1 but still no 5G signal. I was wondering if I can cross-flash this firmware (SM-G9980) for me to enable and use N78 -3500 5G band. Any help/recommendation is appreciated. Thanks.
[Samsung Galaxy S21 Ultra] mpore14:
I believe that you can't. They're two different model numbers. Someone else might have done it and succeeded but as far as i know, they're too different
[Samsung Galaxy S21 Ultra] mapl.ph:
Thank you for your response. Hoping someone here have tried cross-flashing to check if it will work. If this firmware will enable the n78 5G band. My fault for not checking default bands before buying, I was under the impression since they have the same chipset they will all have the same bands but locked by firmware.
[Samsung Galaxy S21 Ultra] thepublocal:
Still no 4.1 love for the G9980 here in the UK :-(
[Samsung Galaxy S21 Ultra] TomasSX1:
Samsung Keyboard got updated and now looks like any other Samsung Keyboard on the world
[Samsung Galaxy S21 Ultra] Ptuk:
Can I see your bands *#2363# on dialler codes. Somebody in US says they have n78 on u1. Have you had the 4.1 update?
[Samsung Galaxy S21 Ultra] mapl.ph:
*#2363# does not work for me? I'm still at 4.0 U1, 4.1 has not come up yet.
[Samsung Galaxy S21 Ultra] Ptuk:
Download the Google dialler. Try with that.
[Samsung Galaxy S21 Ultra] mapl.ph:
Is it just *#2363#? Doesn't work even in Google Dialer.
[Samsung Galaxy S21 Ultra] Ptuk:
Sorry got it wrong...its *#2263#
[Samsung Galaxy S21 Ultra] mapl.ph:
Here you go. After pressing *#2263# , first attachment. But when I select select ALL bands, it shows 2nd screenshot. Current on XAA SM-G908U1 firmware.
[Samsung Galaxy S21 Ultra] Ptuk:
Yes. You don't have n78 but the select all bands option in the service menu is disabled so you still can't get it via that. However another user (see forums) has got it with 4.1 update so maybe wait for that. Let me know as I'd be really interested to see what happens.
[Samsung Galaxy S21 Ultra] mapl.ph:
Hopefully bands are firmware locked.
[Samsung Galaxy S21 Ultra] mpore14:
So curious as to why midrange phones getting the update first before the S21U. Still on Feb patch. The update schedule is confusing
[Samsung Galaxy S21 Ultra] mpore14:
Hi, I've tried flashing the u1 firmware on the 9980. Doesn't work. I would imagine the same if done the opposite.
[Samsung Galaxy S21 Ultra] bodomfan:
Still no one ui 4.1?
[Samsung Galaxy S21 Ultra] afro972:
nope 😅
[Samsung Galaxy S21 Ultra] Aboelnasr:
Someone please wake-up RD team for our Snail 🐌 4.1 update
[Samsung Galaxy S21 Ultra] Matzinger87:
For those who are as impatient as I am:

According to CheckFirm there is already a test build for our device which has the same build version as the firmware already released to most of the other S21U variants. But the date is 29/03 which could mean that we need to wait a few more weeks (!). At least if the FAQs of CheckFirm are correct which state that test builds are released as stable builds within 3-5 weeks after they have shown up in the list. 😞
[Samsung Galaxy S21 Ultra] S1MPTOM:
"discovery date" is the date your application discovered this build IINM ofc (=
[Samsung Galaxy S21 Ultra] Matzinger87:
Your optimistic perspective is most welcome 😄
[Samsung Galaxy S21 Ultra] S1MPTOM:
i've installed this app and there's 31 03 =) so i'm think that's my theory is true
[Samsung Galaxy S21 Ultra] Matzinger87:
Could be. However, according to the app the user "Orlaf XDA" discovered the test firmware (he is also active in the Galaxy S21U forum) and not "my" application . The question is whether build date and date of discovery are the same or not.
[Samsung Galaxy S21 Ultra] :
Samsung is just slow to release chinese firmwares.

...That's all.

[Samsung Galaxy S21 Ultra] Sharpshooterrr:
One UI 4.1 is indeed out now for SM-G9980!
[Samsung Galaxy S21 Ultra] mpore14:
Update installed! So far so good. Will update post when i get the chance
[Samsung Galaxy S21 Ultra] corp0235:
So far with the new ui4.1 update I am NOT loving the Samsung-only apps restriction in the recent apps row at the bottom of the screen when switching between apps.
[Samsung Galaxy S21 Ultra] mpore14:
I turned off the recommended apps. Bottom apps cleared.
[Samsung Galaxy S21 Ultra] hunter1171:
I have a serious issue with my SM-g9980 honk kong not registering my sim card to the network, only one carrier which is the one I'm using, I live in Saudi Arabia and I use STC carrier.

since the December update until this moment I cannot use my sim card until I'm on Wifi calling which is weird.

Flashed to CHC and BRI and still the same issue.

My S21 ultra is just a brick now on WIFI.

I've read a lot of same issue with me.

went to Samsung Saudi and they asked for around 400 US to change the whole board :( saying its a hardware issue not covered by warranty :D

I've donwgraded it to Android 11 , still suffering , please help me not losing my phone for obvious software issue
[Samsung Galaxy S21 Ultra] mpore14:
Hey There, I have cross checked the bands for STC and the G9980 and they are 100% compatible.

Here's the link for the bands used by STC

STC KSA | Powertec Information Portal

Saudi Telecom Company (STC) (شركة الاتصالات السعودية) is a telecommunications company operating in the Kingdom of Saudi Arabia. It was established in 1998, originally as a state-owned entity under the name Saudi Telecom Company. The company provides a range of services including landline...

halberdbastion.com

You can cross check yourself what bands our variant supports (check first post). All bands used by STC are supported.

I would try to do the following:

1. Call up STC and find out if they have a phone compatibilty checker on their end.

2. Try a different sim from STC or put your sim on a different phone.

3. Try a different network provider and see if it works.

4. I would factory reset and flash the latest March 4.1 update TGY/BRI.

5. If none of these work, I woul say that there is a definite hardware problem with your phone and should be covered by warranty if you still got that.

Update us how it goes.
[Samsung Galaxy S21 Ultra] Clarkie_955i:
I have the (SM-G9980) | TGY does anyone now what charging port will be compatible with this. Been looking but can't see any for this specific model. I posted in questions as well but probably should of asked here first.​

Thanks
[Samsung Galaxy S21 Ultra] mpore14:
Are you referring to a compatible part replacement?
[Samsung Galaxy S21 Ultra] Clarkie_955i:
Yes
[Samsung Galaxy S21 Ultra] mpore14:
Hey Clarkie, I have checked witrigs, ifixit, and some other sites and you're right that I couldn't see any specific part for G9980. I would safely assume that one of them U/B/F/N would be compatible. Personally would ask supplier if they know what part would be compatible with the G9980 variant. In saying that, I hope someone from the thread would know where to get it
[Samsung Galaxy S21 Ultra] Clarkie_955i:
I ended up finding this one on AliExpress.

https://www.aliexpress.com/item/1005003412270879.html?spm=a2g0o.order_list.0.0.21ef1802WaPGaH

Sent a couple of messages to confirm the model and stuff and the U goes with the 0. So your pretty much well right. Funny thing was that he pointed the model number out after he replied back. I had a big day at the office so I wasn't even looking properly.

Hey thanks for your reply @mpore14
[Samsung Galaxy S21 Ultra] Clarkie_955i:
Trying to set up Google Pay on this G9980 TGY. Not working for some reason. Is it because I'm in Australia and it is a Chinese phone. Do I have to change CSC or something?

​
[Samsung Galaxy S21 Ultra] mpore14:
Hey there, my understanding is that you can only flash CHC to it and the TGY/BRI rom would default to whichever is suitable for your sim. I don't think that flashing the CHC to it would make much difference. What kind of error are you getting?

All working fine with me here in NZ
[Samsung Galaxy S21 Ultra] Mihalaki:
I've been using Google Pay on G9980 TGY for the past year in Australia no problems. Actually I've had no problems with compatibility with any apps, 5G and other bands all work. Flawless. Might contact your bank?
[Samsung Galaxy S21 Ultra] Clarkie_955i:
All I'm getting is something went wrong as the error message. I have given this phone to my girlfriend and she is a iPhone user and trying to make the transition android. HAHAHAHA

I wonder if it is because she is still logged in with her Apple Pay with the same the card
[Samsung Galaxy S21 Ultra] mpore14:
Probably have to check with your bank as Mihalaki said?
[Samsung Galaxy S21 Ultra] TomasSX1:

[Samsung Galaxy S21 Ultra] netsee1:
can anyone tells me if the hong kong variant g9980 has esim support? i can't find the add mobile plan option
[Samsung Galaxy S21 Ultra] hunter1171:
Thank you for your effort i really appreciate it.

my local Samsung refuse to fix it under warranty saying its a hardware issue,

the funny thing when I connect to WIFI I can see my carrier name and I can call but when I disconnect it disappear,

another proof its a software issue is the photo is attached , the numbers of signals are changing.

other local carriers' sims work on the phone, it's a very narrow issue, unfortunately.

I never been lost in my entire life like this.

guys I don't mind rooting solutions, I really give up on the device and maybe sell it since I practically used it for few months only.

please help
[Samsung Galaxy S21 Ultra] Sharpshooterrr:
CVD6 is out for TGY
[Samsung Galaxy S21 Ultra] Sharpshooterrr:
TGY at CVD6 is back to running warm again while doing anything on your phone. I suggest you skip this update.
[Samsung Galaxy S21 Ultra] corp0235:
N

Not seeing that beahviour on my device. Seems like a good update here.

Anyone else want to share after a few days running it?
[Samsung Galaxy S21 Ultra] SaviourSTR:
Can anyone with experience help me with native call recording in TGY firmware. Is it viable to move to CHC for call recording and while doing so will my data remain as it is or will I have to backup and clean install?
[Samsung Galaxy S21 Ultra] L!V3_4_XC3SS:
CHC is a real pain - China isn't supposed to be compatible with Google Apps - so unless you want Tencent, BAIDU, or a real project with the ADB commandline or Root - I'd stick with TGY - you could tecnically use the Home_CSC and not lose your data but that's a dirty flash and can give you poor results, it's always better to backup your data and restore to a full flash when changing CSC by flashing ROM.

Sorry I know that's not what you want to hear but I've had good results with Cube ACR if you need a good app - I may look into enabling it when my current project is finished.

Best,

L4XS
[Samsung Galaxy S21 Ultra] arrowblade:
I went from CHC to TGY and back to CHC. CHC sucks mainly in that samsung browser only allows you to use chinese default search engines, and the call ID uses tencent services so it's no good unless you're in China. Somewhere along the way from going to TGY back to CHC, it somehow did something and samsung browser remained on TGY settings and i was able to choose english search engines like google and bing. It didn't reset back to when it originally only allowed chinese search engines and I have no idea why, but I call that a win. For google play store, just download the apk from anywhere, it works fine as google play services is already pre-loaded on CHC so all you need is the store. Also, the far left screen uses bixby home and you can't choose the google feed on CHC, so don't flash to CHC if you need the google home feed. Oh I remember now why i went from TGY to CHC. I bought a samsung watch 4 in china, and the china versions are only compatible with CHC firmware and not any other firmware, so that watch forced me back to CHC. I had to reinstall all my data when I flashed back. If you have a non china galaxy watch 4, not sure whether it works on CHC but heard some people had no issues. Overall i dont mind CHC, haven't encountered any big issues which have sent me screaming back to TGY, depends on what you need!
[Samsung Galaxy S21 Ultra] SaviourSTR:
Alright, thanks for explaining! I think that it is too much hassle with even more disadvantages to move to CHC from TGY.
[Samsung Galaxy S21 Ultra] SaviourSTR:
I guess I'll stay on TGY because it seems better than CHC for my purposes. Thanks for explaining so well!
[Samsung Galaxy S21 Ultra] arrowblade:
very welcome!
[Samsung Galaxy S21 Ultra] bodomfan:
Will we see may patch this week
[Samsung Galaxy S21 Ultra] L!V3_4_XC3SS:
Making that significant of an upgrade the way you'd probably want to backup your data and do a complete reflash of your device - This is what I did - DL your latest firmware 2 a PC... samfw.com is my fave repository, and install the latest magisk on your phone. Use your PC to extract your ROM/firmware into a directory so you have the 4 files AP BL CP CSC and CSC_HOME which won't be necessary.

I like my device encrypted because I'm a financier, but If you do like to use custom recovery Afaneh92 made a TWRP port that's compatible, you'll find it with a search TWRP s21 ultra, you can replace the recovery with that if you so desire

Use your pc to copy the AP file to your device with MTP enabled - yes it's 7gb but that's why you bought the fast flagship right? LOL open magisk app and use it to patch the ap file in your downloads - then copy the results back to your PC. That's gonna go in the AP slot and will keep your root. your bootloader is unlocked that won't change with the upgrade as outlined.

BACKUP your data - a full wipe is necessary for good results. Flash it all in Odin and enjoy your android 12.

If you've lost root upon reboot, just use adb to reboot into download mode, and reflash just the modified .tar file patched by magisk with BL and HOME_CSC to keep from resetting your data again, and you should have root when you reinstall magisk.

Quck instructions, there are much more detailed tutorials for each step but I figure you already know most of this. Install Safetynet and resetprops and you're golden.
[Samsung Galaxy S21 Ultra] mapl.ph:
Anyone who can share their carrier_policy.xml on from their device? I would like to check if it can enable 5G on my U1 device. Thanks.
[Samsung Galaxy S21 Ultra] ebowen 747:
I used universal safety net fix. Passes safety net. There was a mode for changing network settings on lg v60. Is there something for this phone?
[Samsung Galaxy S21 Ultra] ebowen 747:
Is there a field test mode for this phone, to adjust network settings and such?
[Samsung Galaxy S21 Ultra] Sharpshooterrr:
May 1, 2022 CVDD is finally out. I hope it fixes heating issues.
[Samsung Galaxy S21 Ultra] bodomfan:
On may update
[Samsung Galaxy S21 Ultra] mpore14:
Looks like a big update.
[Samsung Galaxy S21 Ultra] bodomfan:
Been on it all day
[Samsung Galaxy S21 Ultra] mpore14:
How's it so far? Is there anything significant? I have just installed it. Gonna find out of the battery had gotten any better - not that I care way too much in that department.
[Samsung Galaxy S21 Ultra] bodomfan:
Seems smooth, everything works , battery will take a few days to settle but there is definitely no bad battery drain
[Samsung Galaxy S21 Ultra] Makleroy:
Hello, I recently updated my phone, and after doing so, the second sim card on the phone stopped working, has this happened to anyone else?
[Samsung Galaxy S21 Ultra] bodomfan:
Battery life is worse on may update
[Samsung Galaxy S21 Ultra] afro972:
mine too
[Samsung Galaxy S21 Ultra] bodomfan:
Battery seems like it's settling again,took 3 days
[Samsung Galaxy S21 Ultra] bodomfan:
Give it a few days
[Samsung Galaxy S21 Ultra] afro972:
ok thanks
[Samsung Galaxy S21 Ultra] theartialmartist:
If you or anyone can answer this for me, i'm losing my mind

How are you switching to TGY from BRI in ODIN if Frija downloads *exactly* the same file for both packages??
[Samsung Galaxy S21 Ultra] mpore14:
This is bizarre for me too. I am currently at TGY and hasn't come back to BRI (original). I tried flashing CHC then back to BRI/TGY but it then defaults to TGY. I can't come back to BRI anymore. I have also tried removing sim card while flashing either but it doesn't work.

Maybe this is dependent on the sim card that you have last plugged in? Don't quote me. I hope you find your answer.
[Samsung Galaxy S21 Ultra] theartialmartist:
How did you switch to TGY in the first place? did you manually input TGY into Frija and just flash that CSC?
[Samsung Galaxy S21 Ultra] mpore14:
Yes, that's exactly what i did
[Samsung Galaxy S21 Ultra] theartialmartist:
did it wipe your data? just the CSC file only right?
[Samsung Galaxy S21 Ultra] mpore14:
So, my understanding is that when you download TGY or BRI through Frija, it will give you the exact same one. At one point, I even compared the md5 of the two files and they are exactly the same.

I flashed TGY from Frija and installed everything - BL, AP, CP, CSC - used non-home CSC.

This wiped my data and factory reset.

Now, a month or so later, I wanted to go back to BRI. I downloaded BRI from Frija and flashed the same way with TGY. After all the data wipe and factory reset, the CSC remained at TGY and has remained ever since. I tried to do this another couple of times succeeding months but didn't change back to BRI.
[Samsung Galaxy S21 Ultra] theartialmartist:
What in the Kentucky Fried F..rija...can someone demystify this for everyone?
[Samsung Galaxy S21 Ultra] bodomfan:
Did it cost anything
[Samsung Galaxy S21 Ultra] theartialmartist:
No he's not talking about the paid method, this is the supposed odin method. I can't for the life of me understand how people are saying they freely switch between BRI and TGY - i just want 5G and volte options so i can properly turn them off and stop the IMS service wakelocks and 1% an hour battery drain.

Has anyone tried the U1 firmware? is there a risk of bricking the phone trying this on the OneUI 4.1 May update?
[Samsung Galaxy S21 Ultra] bodomfan:
Same here but don't know how to get it
[Samsung Galaxy S21 Ultra] theartialmartist:
how did you switch from BRI to TGY??
[Samsung Galaxy S21 Ultra] bodomfan:
I haven't
[Samsung Galaxy S21 Ultra] bodomfan:
I want to know if there is a free way to change to tgy
[Samsung Galaxy S21 Ultra] bodomfan:
Mine is a Taiwan model
[Samsung Galaxy S21 Ultra] theartialmartist:
to answer my own question here, again, since nobody ever seems to come back and post their solutions,

The TGY and BRI firmwares are in fact identical, but Odin flashing to the China firmware (CHC?) and back to BRI/TGY forces TGY/TGY/TGY/BRI on the phone (or maybe its because my sim card was inserted this time?) - this still didn't give me 5G connectivity because Taiwan probably added 5g long ago and the posts recommending the TGY change pre-dated 5G there. And since the process factory wiped me anyway i went ahead and installed TWRP for snapdragon, no issues.

Still no 5G on my SM-G9910 using AT&T, I'm calling those ferks back tomorrow.
[Samsung Galaxy S21 Ultra] bodomfan:
So twrp works well? I'm using sm-g9980 but yeah you are right there's not much difference between the firmware
[Samsung Galaxy S21 Ultra] theartialmartist:
yep, i havent run a backup yet (my whole reason for installing) or installed a custom rom, but so far no hiccups whatsoever
[Samsung Galaxy S21 Ultra] bodomfan:
Are you rooted
[Samsung Galaxy S21 Ultra] theartialmartist:
Yep
[Samsung Galaxy S21 Ultra] bodomfan:
Shame this phone has no roms
[Samsung Galaxy S21 Ultra] mpore14:
Is it safe to assume that American variants with snapdragon ROMS can be compatible with ours
[Samsung Galaxy S21 Ultra] qizhi928:
that's good for understood.
[Samsung Galaxy S21 Ultra] bodomfan:
Really, what roms
[Samsung Galaxy S21 Ultra] rubaja:
Hello everyone...

So after updating my S21 ultra with the May 11 update - the 5G band hotspot has been disabled.

Is there a way to unlock it?
[Samsung Galaxy S21 Ultra] corp0235:
SM-G9880 here with the May 19th "CVDD" version installed. Not seeing 5GHz WiFi hotspots disabled on my device.
[Samsung Galaxy S21 Ultra] rubaja:
I have been told that it's not illegal in my country 😡 so samsung disabled it!!

I want to know if there is a way to replace my build.
[Samsung Galaxy S21 Ultra] mpore14:
Im on cvdd and I still have it. It's on Mobile hotspot. Is this what you meant?
[Samsung Galaxy S21 Ultra] bodomfan:
Can't believe we're still on may patch and it's nearly July 🤣🤣
[Samsung Galaxy S21 Ultra] mpore14:
Lol me too. Feels like all the Samsung line and the Exynos versions got it already.
[Samsung Galaxy S21 Ultra] bodomfan:
Yep ,meant to be a flagship device but even mid rangers have had June patch before us 🤣🤣
[Samsung Galaxy S21 Ultra] mpore14:
Lol you're not wrong
[Samsung Galaxy S21 Ultra] bodomfan:
Update policy for Snapdragon is terrible
[Samsung Galaxy S21 Ultra] bodomfan:
Still no update
[Samsung Galaxy S21 Ultra] mpore14:
Yup, my partner's flip 3 got it ages ago.
[Samsung Galaxy S21 Ultra] bodomfan:
This sucks
[Samsung Galaxy S21 Ultra] bodomfan:
I'm getting an iPhone 14 pro max in September, and keeping s21 ultra as my second device
[Samsung Galaxy S21 Ultra] mpore14:
Fair enough. Hopefully it goes well with the iPhone :)
[Samsung Galaxy S21 Ultra] bodomfan:
At least updates will be on time lol
[Samsung Galaxy S21 Ultra] deeplyyoung:
True... Atleast Apple doesn't do partiality while releasing the updates.
[Samsung Galaxy S21 Ultra] bodomfan:
Will we see an update before July 1st on Friday 😂😂 I need it as my camera freezes sometimes and sometimes a video on YouTube freezes the sound continues but the video is frozen , they're the only 2 bugs I have,even after a factory reset and clean installed everything
[Samsung Galaxy S21 Ultra] mpore14:
So far, my only problem has been echoing for wifi calling. It seems another person has this problem but I haven't found this to be the case with other people.

I don't have the camra freezes and Youtube video freezes since this update. Could this be another app in the background? I also assume you're using the latest version of youtube.

Also, if you can be bothered, use Expert Raw. For me, it seems like it takes the better photo than the stock camera app.
