Is anyone else on AT&T having issues with messages not downloading? Wasted over 3 hours on chat with AT&T & Samsung tech support. They had no clue. Both techs even remote accessed my phone - reset settings. I'd love to have everything working the way it should, even if I dont have vanilla google messages, but this is a serious effing issue. Missing messages especially for work can get you fired. On both individual & group texts I randomly get this little bubble that says tap to download and sometimes if I don't see it in time it times out and I can never see what was sent. I tried all the info online about disabling chat features via the Google site. Even put my Sim back in my previous Note 10 plus phone and disabled advanced chat features in old messages app and even downloaded Google messages and disabled chat features from there (even tho I never used Google messages on that phone) They even tried to put me back on the old samsung messages app and the issue persists.

yesterday I flashed U1 and everything seemed to have been fixed. That troublesome group chat that kept refusing to download messages at random appeared to be fixed - until today. I had suspected AT&Ts messed up implementation of RCS as the culprit, but on U1 I'm on Jibe.

This is the most expensive flagship samsung's got rn and this is going on?! need a fix or am going to return and back to my note 10 plus which never had this issue
[Samsung Galaxy S22 Ultra] hyelton:
Which mirror you talking about? Mine is working fine

Edit: oops looks like you got it
[Samsung Galaxy S22 Ultra] aschaffer35:
Thanks man. I'll give that a go this evening.
[Samsung Galaxy S22 Ultra] Justinphxaz:
I noticed kinda crappy battery life for a few days after getting the S22 Ultra (I know the battery optimization can take a few days) when I compared it to my almost 2 year old Note 20 Ultra. Things are pretty good now, maybe slightly better battery life overall now, when compared to the Note 20 Ultra. I removed bloatware which seemed to help, set the permissions to put a grip of apps to deep sleep and or turned some off completely.

But I've noticed that the signal seems to bounce around a lot, even when not moving around and remaining stationary. For example, I'll be laying in my upstairs bedroom and I'll constantly cycle through 5GUW, 5G and 4G LTE (I really only see 5GUW when upstairs and not downstairs, except maybe once or twice for a quick second otherwise it stays cycling between 5G and 4G LTE downstairs). I've seen signal strength degrade to around -105dbm or so and then suddenly get better and be around -85dbm. When I'm on 5GUW and see around 2-3 bars, DL speeds are usually something like 80mbps - 170mbps.

About 2 nights ago I tried turning on airplane mode to refresh everything. I quickly noticed that for about 5-10 minutes after I reset the modem using airplane mode, remaining in the exact same spot, I saw full bars of 5GUW and it remained locked on full bars (sometimes as strong as -77dbm) and remain in that excellent strong signal in 5GUW for 5-10 minutes (my DL speeds were also much faster, usually around 300 - 600mbps during this time right after cycling airplane mode)

So, I've definitely noticed much better battery life by doing this a few times a day. The signal seems to stay and remain strong and not fluctuate nearly as much now (even when connected to 5GUW the same amount everyday as before) when I wouldn't cycle airplane mode.

It sure would be nice if engineering would look into this. Maybe a fix for the modem could implemented, as it is possible to get stronger signals and remain stronger for awhile (even while remaining stationary in the exact same spot, where before I cycled airplane mode, the signals were constantly changing and fluctuating). This seems to calm the cycling down a bit, at least for a little while and the signal also seems to improve during this duration and has in my case, provided me some extra longevity in battery life. If you haven't already gotten a new device and haven't tried this, maybe try giving it a go, hopefully it helps some.
[Samsung Galaxy S22 Ultra] Justinphxaz:
Is the issue still happening now? I saw an article earlier this morning that many Google services are down. Hopefully it'll work itself out shortly.
[Samsung Galaxy S22 Ultra] hyelton:
Is it odd an MVNO gets the update before everyone else?
[Samsung Galaxy S22 Ultra] Mtotallywired:
It's been happening honestly since I got the phone on February 21st. Didn't really notice it for maybe the first 3 or so days but it's been pretty consistent since then. Really thought it'd be fixed now that I'm on Jibe but nope. Also having issues on non group chats with fellow AT&T Android users trying to send me pictures - in two instances they were on S21 Ultra / S21 Devices using the stock Samsung Messages App (Non Google)
[Samsung Galaxy S22 Ultra] Markeee:
Yeah and lately its been my MVNO Xfinity Mobile that always seems to get it first.

Considering whether I should flash my factory unlocked U1 over to carrier U to take advantage and get the upgrade right now.

Pros and cons stay unbranded wait or go carrier U ?
[Samsung Galaxy S22 Ultra] DLD23:
Well, I learned my lesson. I got a U1 SD 22 Ultra in USA and am on ATT. I flashed to the carrier firmware thinking somehow it was going to be better with features. Dead wrong. Lol ATT firmware is worst battery life ever. I was getting 9+ hours SOT on U1 and on ATT was less than 6. From now on I will Never use carrier firmware. I flashed back and am back on U1 firmware.
[Samsung Galaxy S22 Ultra] Markeee:
Did it make u reset and clean install or where u able to like dirty flash and did it install a mess of bloat ?
[Samsung Galaxy S22 Ultra] DLD23:
No I installed from u1 to U clean. Just like windows- updating an OS sucks. Lol always clean install a new OS major release.

Then when I went back to U1 I clean installed also. No dirty flash.
[Samsung Galaxy S22 Ultra] Markeee:
Yeah clean installing and getting everything just right is like a project that can take a few hours
[Samsung Galaxy S22 Ultra] southern87:
Give me about 5 min maybe and I'll have a mirror for the new Carrier update. Downloading it now to my NAS to sync to Google drive.

Uploaded them to 1 Google drive. Forgot I had unlimited on one.

Edit. Here they be

S908U1UEU1AVA6

S908USQU1AVC8

S908USQU1AVA6
[Samsung Galaxy S22 Ultra] hyelton:
I'll upload the new update on my server tomorrow looks like TMobile just got it at some point in the past few hours.

One warning about Google drive though, after so many downloads If it gets popular they'll disable the link
[Samsung Galaxy S22 Ultra] southern87:
Yeah they have a daily limit I've read but I doubt it will get hit here lol. It's like 10TB down a day or something.

I have gigabit internet. Will take a few minutes to re-upload if need be.
[Samsung Galaxy S22 Ultra] joemossjr:
tmobile installing now
[Samsung Galaxy S22 Ultra] butchieboy:
Has anyone on At&t got Ota? U variant?
[Samsung Galaxy S22 Ultra] Markeee:
Guess we don't have to wait Just getting the US OTA U1 update now

Done
[Samsung Galaxy S22 Ultra] ltmikepowell:
I just got it too. U1 S22U on TMB.
[Samsung Galaxy S22 Ultra] duracool:
I guess not. I'm on AT&T and I'm still waiting for the update..
[Samsung Galaxy S22 Ultra] hayabusa1300cc:
I notice it's just posted but I happen to check for a download and it's here. T-Mobile
[Samsung Galaxy S22 Ultra] jerrycoffman45:
still waiting here
[Samsung Galaxy S22 Ultra] dia_naji:
So confused... When I flashed the firmware a couple weeks ago. I was under the assumption it was a TMobile firmware, but I have yet to get the update and I still think I am on the unlocked US firmware
[Samsung Galaxy S22 Ultra] Venom0642:
Nope not yet i flashed.
[Samsung Galaxy S22 Ultra] dia_naji:
Can anyone help me out? I'm I on the TMobile firmware? I downloaded the firmware from this thread.
[Samsung Galaxy S22 Ultra] Paul_Deemer:
U.S. Unlocked Update now available.
[Samsung Galaxy S22 Ultra] dia_naji:
I haven't gotten anything. I don't even know if I'm on the TMobile or unlocked firmware
[Samsung Galaxy S22 Ultra] brachiopod:
Oh, I'm still on Jan 1 U1 on ATT NVMO and not showing anything yet. It is about time though!
[Samsung Galaxy S22 Ultra] Paul_Deemer:
I had to manually check for mine today before it would download.
[Samsung Galaxy S22 Ultra] brachiopod:
I'm checking, there is nothing! What is your CSC, mine is XAR/XAR,XAA/XAA
[Samsung Galaxy S22 Ultra] dia_naji:
My CSC is the same as yours and still haven't gotten the update
[Samsung Galaxy S22 Ultra] Paul_Deemer:
TMB/TMB,XAA/XAA
[Samsung Galaxy S22 Ultra] brachiopod:
Maybe just out on T mobile then. ATT is always slow.
[Samsung Galaxy S22 Ultra] Paul_Deemer:
Well I do have TMobile Prepaid but the Phone is not a TMobile model.

It's the 512gb Unlocked model with no carrier software installed.
[Samsung Galaxy S22 Ultra] dia_naji:
Anyway you can help me out? I'm seeing a lot of TMobile phones with updates. I flashed the firmware from the second post I believe. I was under the impression this was the TMobile firmware, but have yet got the update
[Samsung Galaxy S22 Ultra] hyelton:
. Did you flash the CSC and user data?

The U1 XAA model also has updates out.
[Samsung Galaxy S22 Ultra] dia_naji:
Delete this please
[Samsung Galaxy S22 Ultra] dia_naji:
I Flashed both the CSC and user Data as per instructions. What can I do right to get the T-Mobile firmware. Do i have to do a clean install? Or can I preserve my data
[Samsung Galaxy S22 Ultra] hyelton:
Did you flash CSC or home_csc? When changing firmwares like that its always recommended to start clean.
[Samsung Galaxy S22 Ultra] hyelton:
Mirrors for the latest firmware

U1 SM-S908U1_S908U1UEU1AVC8_XAA

TMB T-Mobile - SM-S908U S908USQU1AVC8_TMB

Also seperate userdata files here in case its needed. Adding more soon
[Samsung Galaxy S22 Ultra] Kris_b1104:
Can I dirty flash the U1 update over my firmware? I'm on AT&T locked carrier but unlocked firmware.
[Samsung Galaxy S22 Ultra] freebee269:
You can. But you may have some battery drain you don't like. I would just clean flash the u1. That's what I did on my AT&t branded s22 ultra. Now I have the u1 firmware but the CSC still shows at&t. So now I can just grab this file and only flash the AP bootloader and CP file and leave the CSC alone.

In this screenshot you will see the service provider software is u1 but the CSC at the end of it all says at&t.
[Samsung Galaxy S22 Ultra] hyelton:
Ill probably switch from TMobile firmware to u1 soon. Just waiting on TMobile to unlock first. Cause you can't unlock while on U1 firmware. You'll have to flash TMobile back to be able to unlock
[Samsung Galaxy S22 Ultra] JeKaSBaLTo:
Do I have latest firmware?
[Samsung Galaxy S22 Ultra] Venom0642:
You put your ime i would take that out, people can hack your ime.
[Samsung Galaxy S22 Ultra] DLD23:
From experience, I 2nd that! Start clean. Always good results. ATT, even with clean install, is terrible battery drain. Clean U1 is the best of the 2. I cant speak for the other carrier U firmwares.
[Samsung Galaxy S22 Ultra] brachiopod:
Well, XAR is tracfone, ATT NVMO, I'm on straight talk on ATT. It is probably possible to take out the SIM, change the CSC to XAA with the keyboard command, get the update, then put the SIM back in. I used to have to do that to get my old Note 20 to update sometimes so I didn't have to wait. In fact, I'll try it and report back. (and he was never heard from again...)

Update: that didn't work, the keypad code does not seem to work any more although it did on my Note 20U.
[Samsung Galaxy S22 Ultra] aschaffer35:
So i did the flash to u1, then to u and I saw the magenta TMobile pop up and looks like I'm good now! Interesting how you have to go to the U1 then U to get the carrier stuff to update but whatever lol. It's fixed. Thanks so much for this suggestion my good sir!

Oh and I got the OTA to AVC8 as well woot!
[Samsung Galaxy S22 Ultra] joemossjr:
U1 wipes carrier files and U puts them back in place. Been doing this since this first Galaxy lol gets weirder every year
[Samsung Galaxy S22 Ultra] DLD23:
I just did u1 ava6 to the new ui with odin while only flashing those 3 files and no csc or userdata and it wiped my phone. I believe the home csc is needed. Not if I go to software update in menu, it says software version not supported. Other than that all good. Ill just flash next update with home csc.
[Samsung Galaxy S22 Ultra] aschaffer35:
With my note 10 when I switched to att previously it did it all by itself lol. Guess these things just do what they want sometimes lol. Thank God for these forums!
[Samsung Galaxy S22 Ultra] freebee269:
Now flash the march u1 update before setting up your phone so that you're up to date. Use the CSC since you haven't set up your phone yet. Completely clean flash.
[Samsung Galaxy S22 Ultra] kangi26:
Adding a link to U1-AVC8 to post 3 as soon as it finishes uploading
[Samsung Galaxy S22 Ultra] Jobudden:
I'm hoping we can get one for Verizon soon lol
[Samsung Galaxy S22 Ultra] DLD23:
Well I set it all up. But ill do on next update. Thanks
[Samsung Galaxy S22 Ultra] DLD23:
I did smart switch backup to and restore apps and settings from external usb and worked great on restore. Biggest annoyance is it does not save my choices under display for full screen apps to show camera cutout. That takes a few mins lol. It doesnt seem to reduce my battery this way as long as my backup was from a u1 same as what I came from. It even keeps my settings for apps that I set for restricted battery use and blocked notifications. Totally clean is always superior of course, this is just a time saver :)
[Samsung Galaxy S22 Ultra] kraz01:
Could the t-mobile firmware be used for At&t like the initial firmware that is in post #2?
[Samsung Galaxy S22 Ultra] gettinwicked:
So, I clean flashed to U1 a while back from the Verizon version. I'll get the unlocked OTA, right? It was the U1 version in the OP.
[Samsung Galaxy S22 Ultra] hyelton:
In the process of backing mine up now T-Mobile U firmware. Think I may flash U1. Still trying to decide If I want to or not or even worth it. Main reason is currently having weird data issues where data is just dead until I airplane mode or just wait for it to come back (in a fringe coverage area). Other devices are not having this issue.
[Samsung Galaxy S22 Ultra] kangi26:
​

From Post #1

All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get OTA when you flash it.

The firmware packages house each of the carrier's information, features, bloat, splash screens etc. (That's why they roll in at over 7Gb). When you flash a firmware the installation package reads your SIM, determines what carrier you're using and then installs the "package" that's designed for your carrier​
[Samsung Galaxy S22 Ultra] hyelton:
After waiting 5 hours. It fails at the last minute... Wonderful 😂
[Samsung Galaxy S22 Ultra] DLD23:
I personally would. ATT is basically the same. My 5g on ATT works fine on U1, just dont restore phone settings, just do apps and you will be fine. None of the bloat gets backed up- only user installed apps.
[Samsung Galaxy S22 Ultra] hyelton:
After finally flashing U1 its instantly a better feel just normal setup etc.. Twitter is still a laggy mess but over all stock UI is a ton more fluid!
[Samsung Galaxy S22 Ultra] ltmikepowell:
With the S22 series I don't think there is any reason to flash carrier firmware into U1 device at all. With my Note20 before I have to flash TMB U firmware to get ESIM, but my S22U already come with ESIM on U1 firmware so no need for carrier bloatware on it.
[Samsung Galaxy S22 Ultra] slime340:
I have a question that may have been answered already and if this is the case, my apologies. Is there a way and/or an advantage to use the firmware of an unlocked device onto a carrier locked device. I bought my phone from T-Mobile, and while there own software touch is light, comparatively speaking, I don't like having it, especially the splash screen. Thank you in advance for the response.
[Samsung Galaxy S22 Ultra] slime340:
Yep I was right, everything I needed was right above my own post.
[Samsung Galaxy S22 Ultra] yeltrah123:
I have a question. This possibly might have been brought up in the 34 previous pages before this, but I don't feel like going through all of those pages. I have Odin3_v3.14.1 can I use that to flash U firmware on my U1 S22 Ultra? Did Anyone try this, if so did it work? Thanks.
[Samsung Galaxy S22 Ultra] Markeee:
I always use the patched version below link never had a problem works perfectly every time

Patched Odin 3.13.1

For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

[Samsung Galaxy S22 Ultra] butchieboy:
Some think that unlocked is better. But for me personally I never notice a difference. As far as bloat, I just disable what I want.
[Samsung Galaxy S22 Ultra] kangi26:
Glad you got your answer, but as a side note, your question was answered in post #1
[Samsung Galaxy S22 Ultra] Jobudden:
For me it's because Verizon blocks the use of Samsungs back up features
[Samsung Galaxy S22 Ultra] dj24:
Some anecdotal viewpoints mostly from Exynos users in other threads have mentioned that the March update has made their phones worse. Anyone here notice anything similar after updating?
[Samsung Galaxy S22 Ultra] Jobudden:
Still on a January patch lol
[Samsung Galaxy S22 Ultra] DLD23:
I can confirm this also. "Patched works for all" as a wise man once said lol.

I have went from u1 to u and back to u1 with no issues. When I went from u to u1, I took out my sim card then went through the setup and put sim card in after(no need to power off phone for putting sim card in)

Not sure if that is needed, but was successful for me.
[Samsung Galaxy S22 Ultra] dia_naji:
If I flash this would I get the T-Mobile splash screen and the T-Mobile data icons? For some odd reason my service provider software version is still showing XAA. I had the sim card in when i did the flash and I used the CSC and USERData. Really don't understand what I am doing wrong

Update: I took the SIM card out and put it back in when it rebooted and still getting XAA. Shouldn't it be showing XAU or TMB?
[Samsung Galaxy S22 Ultra] DLD23:
The u1 will never have the splash screen. You have to flash the u with the userdata. The u1 with the userdata is basically a "dirty flash" if you want splash screens download 908u and tmb on frija and flash the files.
[Samsung Galaxy S22 Ultra] dia_naji:
I have never had this issue in the past though. Normally I always buy unlocked phones from samsung. Download the firmwire from sammobile or samfew. Match all the correct file names in odin including the USRdata and CSC and it would work like a charm tmobile splash screen and the correct tmobile icons.. Unless something was changed this is the method I have used to switch from a U1 to U.
[Samsung Galaxy S22 Ultra] efrancis1409:
I just dirty flashed the March U1 update on to my at&t locked S22U which was still stuck on January U1. No noticable issues or battery draining so far. Multi window app frame drop issue is still present though.
[Samsung Galaxy S22 Ultra] dia_naji:
I am striking out all over the place tonight. I am trying to flash the U1 firmware then the TMB firmware. Odin is stuck on SetupConennection. I've tried various versions including the one included in this post. Any help?

Update: Finally it worked! I had to flash the U1 Firmwire first then the U. I have the T-Mobile splash screen and the correct data icons. I used the latest odin patched 3.14.13B. My main issue to why Odin wasn't working because i had the cable plugged in USB 3.0. Odin hates 3.0. I really appreciate all the help. Expect donations from me to everyone who has contributed. Thanks!

[Samsung Galaxy S22 Ultra] dia_naji:
Yup and now I can't even get into download mode. An error has occurred while updating device software. God this is turning into a nightmare
[Samsung Galaxy S22 Ultra] Markeee:
How about booting into recover mode and take it from there ?

Wipe data and factory reset ?

Sucks when **** don't go smooth issues can pop and sometimes you don't have a clue what's causing it and how to fix it

Then you have to come here feeling like you begging for some help
[Samsung Galaxy S22 Ultra] dia_naji:
Phew.... Got into recovery and did a factory wipe then finally got into download mode and flashed hyelton's TMB firmware and that worked. Weird What I was trying to do is Flash the U1 Firmware then the U tmobile firmwire, but when I flashed U1 it failed half way through. All because I wasn't getting the march update on my XAA and wanted the phone be a T-Mobile Branded phone.
[Samsung Galaxy S22 Ultra] butchieboy:
Usually when going between U and U1 you have to factory reset first. Also when you get the emergency failed screen you can flash firmware from that screen
[Samsung Galaxy S22 Ultra] je2854:
I have the Verizon U and DID in fact flash to U1 without a single issue.
[Samsung Galaxy S22 Ultra] Markeee:
Glad it worked out I almost flashed from U1 to U just coz I didn't feel like waiting for the U1 to drop waiting sucks glad it came out fast i didn't wind up going through that whole mess
[Samsung Galaxy S22 Ultra] ekerbuddyeker:
On the latest version of U1 (for an unlocked device) I have noticed that since this update when leaving wifi, sometimes the phone goes to H (and stays there) and not LTE. have to airplane mode on / off to get to to get LTE. Anyone else notice? That is a new issue for me. Didn't happen before.

Is there an 'agressive' mode to fix this?
[Samsung Galaxy S22 Ultra] butchieboy:
I'm starting to think that I'm glad I have updates disabled since many are having issues.
[Samsung Galaxy S22 Ultra] D.W.H:
On AT&T with the U1 software, just got the update. Let's hope it isn't trash. lol
[Samsung Galaxy S22 Ultra] dj24:
Some anecdotal viewpoints mostly from Exynos users in other threads have mentioned that the March update has made their phone worse. Anyone here notice anything?

I've paused mine as well since I've seen a decent number of users (mostly exynos) with complaints after they updated. Things are fine from my end and I figure why mess with something that's not broken?
[Samsung Galaxy S22 Ultra] Maxninja:
This is curious, with you having an U1 device on ATT and getting an OTA, I checked sammobile firmwares and it shows "USA (ATT) S908U1UEU1AVC8" While U selection doesn't list ATT in it's firmwares? Do I need to flash U1 (unbranded) edition of ATT firmware to receive ATT OTAs? (I know I have the carrier U edition, but still WTF?)
[Samsung Galaxy S22 Ultra] JeKaSBaLTo:
I didn't get any updates since feb
[Samsung Galaxy S22 Ultra] Venom0642:
I never had any issues at all with my AT&T S22 Ultra on the January patch and the March patch I'm on, Sucks to be Exynos
[Samsung Galaxy S22 Ultra] kangi26:
Take a look at post 1, it answers your question
[Samsung Galaxy S22 Ultra] Maxninja:
No, it does not answer my questions. My questions are regarding the U and U1 ATT firmware being listed in the unbranded tab and not in the carrier tab and then asking if I need to flash the unbranded att firmware to receive OTAs, while the phone not receiving the OTA even though the unbranded device has the ATT update. The first post does not answer this.
[Samsung Galaxy S22 Ultra] D.W.H:
I have no idea. This is originally a SM-S908U device that I flashed the U1 firmware to. The good thing about the U1 for me is that I can check as many times as I want for the update and not once every 24 hours like on the AT&T firmware. Now, from my understanding the U1 firmware isn't carrier dependent and is pushed by Samsung. My guess is that AT&T didn't push their branded firmware update yet and it might be soon, but they're always slow. Maybe give it a few more days.
