[Samsung Galaxy S21 Ultra] Skander1998:
That won't work, and is completely irrelevant to the issue at hand. This only applies to the unlocked US model (U1) - the OneUI 4 update misconfigures VoLTE for international SIMs.

U will work, but the branded firmware shouldn't be required, U1 is currently broken.
[Samsung Galaxy S21 Ultra] aps99:
Did you lose the data? I already factory reset my phone trying to fix this issue, rolling back etc.
[Samsung Galaxy S21 Ultra] lui0703:
I did a full backup before. And just restored the data via Smart Switch after.
[Samsung Galaxy S21 Ultra] aps99:
Just to confirm. Are you having a US phone which is being used outside US? What is your current carrier?
[Samsung Galaxy S21 Ultra] Kanwal85:
Will you please elaborate the whole procedure how did you installed this rom roll back to one UI 3.1 safely..

I have USA unlocked variant of S21 ultra and i am on stable One UI 4.0. Facing the issues.

..VOLTE AND WIFI CALLING FEATURE NOT WORKING ..

YOUR HELP WOULD BE HIGHLY APPRECIATED
[Samsung Galaxy S21 Ultra] Kanwal85:
Bro I have unlocked US variant of s21 ultra using in India on jio sim .. volte and wifi calling not working 120hz refresh rate bug is also there .. please provide the detailed procedure once you have fixed these issues
[Samsung Galaxy S21 Ultra] aps99:
Resetting the network settings won't help.
[Samsung Galaxy S21 Ultra] Kanwal85:
Not its not working I already did this
[Samsung Galaxy S21 Ultra] Kanwal85:
Have you formatted and tried to roll back to one UI3.1?
[Samsung Galaxy S21 Ultra] aps99:
I didn't roll back to OneUI 3.1 from the (un)stable OneUI 4. But, I did roll back from OneUI 4 beta to OneUI 3.1.

I saw someone posted a link for the exact process involved. I think he/she used Odin.
[Samsung Galaxy S21 Ultra] Kanwal85:
Ohh ,ok please let me know in detail if you would be able to roll back using odin .. I let you know too if I found any alternative to fix it ... I am tweeting smasung USA and posting on samsung Community USA to find best way ..
[Samsung Galaxy S21 Ultra] lui0703:
Ok. First I didn't roll back to OneUI 3.1.

1. I used Frija tool to download Android 12 rom, I used SM-G998U for model and SPR for CSC.

2. After the download was complete I backed up my phone using the PC version of Smart Switch.

3. I used patched ODIN 3 v3.14.1_3B_Patched to load the firmware, I put AP, BL, CP, and CSC (not Home CSC). I didn't use the UserData file.

4. After phone restarted it gave me an error message about system and requested that I do a Factory Reset.

5. After Factory Reset phone boots normally into Samsung Setup with no boatyard.

6. Use Smart Switch to recover data, and everything should be working fine, including VoLTE and Video Calling

I hope this helps.
[Samsung Galaxy S21 Ultra] lui0703:
Yes I have a US phone and I am currently using it in China.

You can check the screenshots. I have the HD symbol for VoLTE, I left the country code of my sim to show I am in China, and you can check the software version, and service provider software it is a US model S21 ultra
[Samsung Galaxy S21 Ultra] Kanwal85:
Does ot works for wifi calling
[Samsung Galaxy S21 Ultra] Kanwal85:
Bro did it fix 120hz refresh rate bug and wifi calling bug?
[Samsung Galaxy S21 Ultra] lui0703:
The 120hz bug is universal I think. I know that Samsung are trying to fix this.

Wifi calling should be working, my service provider doesn't offer it so I can't test that.
[Samsung Galaxy S21 Ultra] lui0703:
If you want a bug free OS, roll back to OneUI 3.1 it's the best option.
[Samsung Galaxy S21 Ultra] Kanwal85:
Ok thanks alot bro .. one more thing want to ask that do we get future updates if we install this Rom? One more thing I think if you install the same rom dedicated for your model without copying user data might have fix your issues . I have just guy feeling for this .. You may try this because your have all tools already but I EVEN dont have computer and have to arrange from somewhere else..
[Samsung Galaxy S21 Ultra] lui0703:
It's an official Rom, so you can receive future updates OTA.

Not sure about the last part though, because only carrier specific roms have user data. But you can try, and hope you succeed bro
[Samsung Galaxy S21 Ultra] Kanwal85:
My phones model no is SM-G998U1 but your phone model is SM-G998U. So will this method works for me what do you think
[Samsung Galaxy S21 Ultra] lui0703:
U and U1 are the same. U just means that it is a rom from a specific carrier, U1 means it's unlocked or has no carrier.

Previously I was on U1 rom but had the problems discussed in this thread, and I changed to U rom, and it fixed them. I think samsung broke the settings for IMS in the U1 OneUI 4 update.

U and U1 are completely interchangeable, don't worry about that.
[Samsung Galaxy S21 Ultra] Kanwal85:
Ok bro thanks
[Samsung Galaxy S21 Ultra] Kanwal85:
Bro you you are saying U mean a rom from specific career .. if its locked for specific career then will it work for indian career (Jio/airte) etc
[Samsung Galaxy S21 Ultra] lui0703:
Yes it's U but unlocked
[Samsung Galaxy S21 Ultra] Kanwal85:
Ok 👍

[Samsung Galaxy S21 Ultra] lui0703:
Hey bro. IMS settings are carrier specific. Like I mentioned before, my carrier does not offer wifi calling. And those settings I don't think can be toggled from this menu.

However I did attach the screenshot from the service menu
[Samsung Galaxy S21 Ultra] Kanwal85:
Hello bro in developers option I did' find OEM toggle button so I dont know OEM of device is locked or unlocked and can I flash rom with locked OEM.?
[Samsung Galaxy S21 Ultra] lui0703:
If it is an official rom you can flash. If it is not you need to unlock OEM
[Samsung Galaxy S21 Ultra] lui0703:
If you use Frija or sammobile, the rom is official so no worries bro
[Samsung Galaxy S21 Ultra] Kanwal85:
Ok you means, if we download android 11 based 3.1 rom from sammobile/friza then we can downgrade without any issue?
[Samsung Galaxy S21 Ultra] Kanwal85:
Bro have you rolled back from stable 12 to stable 11 one UI 3.1 or did some other fix please let me know
[Samsung Galaxy S21 Ultra] aps99:
I didn't roll back from stable 12.
[Samsung Galaxy S21 Ultra] Kanwal85:
But there is guy who installed SM-G998U using odin get fix .. what you say about this.
[Samsung Galaxy S21 Ultra] aps99:
Yeah. I saw that comment. I didn't try that. It might work.
[Samsung Galaxy S21 Ultra] Kanwal85:
I am thinking to flash the same rom of android 12 (which we got via FOTA) using odin .. hope it will fix it
[Samsung Galaxy S21 Ultra] aps99:
Do let us know how it goes.

From where are you planning to download the ROM for SM-G998U?
[Samsung Galaxy S21 Ultra] Kanwal85:
From sammobile.com
[Samsung Galaxy S21 Ultra] aps99:
That might be slow. I recommend installing Samsung Firmware Downloader APK and download from there. It gave me the best speed.
[Samsung Galaxy S21 Ultra] Kanwal85:
Yea but i dont have computer and lappy , so
[Samsung Galaxy S21 Ultra] aps99:
You don't need that. You can download on your mobile.

Desktop versions limit the download speed to 1.2 MBps. Android version doesn't limit it.
[Samsung Galaxy S21 Ultra] aps99:
You can download it from here.

[Samsung Galaxy S21 Ultra] Kanwal85:

[Samsung Galaxy S21 Ultra] ndjasani:
i suggest all those who are still on oneui 4 - pls submit an error report on the samsung members app with all the details - esp mentioning that its an unlocked phone bought in the US and not working when travelling to other countries like India.

To submit report - open Samsung Members app->Get Help (lower right)->Error report
[Samsung Galaxy S21 Ultra] Kanwal85:
But our samsung member app is Indiana so eroor report will also goes to samsung India and they already told us that can't do anything in this
[Samsung Galaxy S21 Ultra] panks_4ever:
I am following this thread since last week once I got the android 12 update, it broke WIFI calling and I am currently in India using Jio which left the phone useless. Had multiple visits to the Jio store. One solution they offered was to install the JioCall App which temporarily fixes the issue and you can make / receive calls. As a permanent solution i thought porting out to VI / Airtel was better option than to flash new roms / downgrade to Android 11.
[Samsung Galaxy S21 Ultra] panks_4ever:
Hey - Please let us know if you happen to flash the same rom and whether the issue got solved or not.
[Samsung Galaxy S21 Ultra] Kanwal85:
Bro still I didn't Arrange PC/Lapp.. but on samsung community I saw One of the user downgraded to ONE UI 3.1 ..

Can't make or receive calls

After the software update I can't make or receive calls. And messages always says blocked. Please help!

Just got system configuration update and it has fixed this issue. I would suggest to wait as fix has already been released
[Samsung Galaxy S21 Ultra] Vazovski2007:
Hi, Thanks for your information that would help

unfortunately I have waisted lot of time to find out the reason and U firmware helped, could you be so kind to check 1 thing if you are still on U1 ? and VoLTE is working? if yes please can you tell us if the phone number is visible in About Phone > Phone number?

because on U1 firmware it was never being visible even on android 11
[Samsung Galaxy S21 Ultra] dp1989:
Yeah, I have U1 model and volte does work now. However there's a bug if you are using volte wifi calling. In case, you connect your device to another wifi, volte goes away and only fix is to reboot the device. Regarding phone number, yeah I can see it in about phone.
[Samsung Galaxy S21 Ultra] Vazovski2007:
Oh thats super, im not using Volte Wifi call, im using only Volte for calls vida data connection

I've just gotten an update on my G998U1 and it has restored my VOLTE functionality. The firmware was BULH. I'm currently using the phone in Malaysia and tried with multiple telco provider sim
[Samsung Galaxy S21 Ultra] Vazovski2007:
Your phone is s21 Ultra as far as i understand and based on your firmware version it is an update not only the security update (U char 6th from right to left) and s21 have only Security update (S symbol) anyway thanks for sharing hope Samsung will roll out this fix for other models as well
[Samsung Galaxy S21 Ultra] Vazovski2007:
very interesting, sims Samsung started roll out just yet since i couldn't find BULH firmware even on sammobile
[Samsung Galaxy S21 Ultra] suphion:
I can confirm in Turkey, volte and vowifi finally started to work immediately after updating to BULH for 998U1 fw

The update is OTA though, that may be why it isn't on samfw sammobile yet, it will probably be there soon unless you have it OTA already
[Samsung Galaxy S21 Ultra] Vazovski2007:
Thanks for confirmation I'll try on 991 U1 as soon as it will be available on s21
[General Questions and Answers] Psycho-A:
Hello everyone!

I have Sony Z3 Compact phone with touchscreen replaced to chinese replica, and there is a problem with determining the coordinates of the sensor touch. The further away from the middle of the screen, the more the sensor lies about the coordinates towards the edges of the screen.

Is there some app or build.prop/core patches for that redefines the coordinates of touches? I couldn't find. I head about touch.size.calibration or touch.size.scale etc params in build.prop, but this not seems to be the same I need, and didn't work for me at all...
[General Questions and Answers] tracid1987:
I have just bought display with touchscreen from aliexpress ( xinzhixing Store) for 18euros and i have different problem. It is often registering short touch as long touch (or some kind of unknown gesture). i want to open an app and it first looks like it is freezing but then it places the app icon elsewhere. its doing it often, it is annoying. I dont know if there is any kind of software solution to it, this phone was laying for 6 years and now i wanted to set it up as secondary spare phone so will dig up xda forums later.

But i am afraid that this is the price we have to pay for buying a chinese display/touchscreen :)
[Sony Xperia 5 III] WarVic:
Hello everyone. It sounds like waste of money, I know, but has someone upgraded from Xperia 5 II to Xperia 5 III? Any noticeable photo quality improvement, better focusing, better photo consistency?
[Sony Xperia 5 III] Yakkosmurf:
I’m curious as well.
[Sony Xperia 5 III] tatdatnt:
More details, better focusing, better tele photo, higher shutter speed & faster photo saving as well. But generally not much of the improvement from 5ii.
[Sony Xperia 5 III] tatdatnt:
Samples. you can see the config in file properties.
[Tilt, TyTN II, MDA Vario III General] ThunderDick:
After Kaiser Tweaks installation, I had lot of problem with backlight management.

I had already solved the problem of the backlight dimming after locking, removing the registry item.

But after using KaiserTweaks, that key randomly reappered. Randomly, meaning that if I delete it now, then it comes back two days later, or 5 days later, etc...

Now, deleting and deleting it many times, maybe because of other options properly checked, that key is no more reappearing, and everything seems ok (Kaisertweaks had already been uninstalled since few weeks).

What I don't understand is the backlight manager. Tapping on the icon in the htc today plug-in, I usually obtained a form with two sliders, battery and plugger power backlight settings. Now, I obtain a different backlight manager, with only the checks for "switch off backlight when phone not used for... minutes", but no sliders.

In the settings tab, I have TWO different Backlight icons. One starts the original backlight manager, the other starts the new one.

How can I link the htc today plug-in backlight icon to the proper manager???

Bye
