Hi at all,
I have a problem, which will only affect a few:
I live close to the border of my country (Germany), so that my cell connects to the network of the neighboring country. Somewhere near the update from Android 6 to 7, my phone stopped showing my home carrier network (o2) in the manual network selection. Literally all other carriers are shown. This is super crappy, as even with disabled data while roaming, the phone used some data in the neigboring country.
Annoyed by that, I did the manual update to Android 8 to see, if this solves my problem. Unfortunately not. As EMUI is also not my favourite of all time, I tried the OpenKirin LineageOS, but still the same. Does anyone have similar problems or know a solution? I owned a Samsung phone in the past, where I manipulated the radio image for reasons. Does anyone have experience with that on the Huawei?
Addendum: In my ancient HTC One, manual network selection with the SIM card works find on a custom ROM. The mainboard of the phone has been exchanged by Huawei, so I guess hardware is also not the issue.
Best regards,
kønich lars
So I bought a SM-N950N Note 8 in October 2017 and has been great until now where it cannot receive or make phone calls. Everything else works fine - SMS, mobile Data, everything. Just unable to make or receive calls.
I have done everything that I have found on the internet from resetting network settings, resetting cache partitions, factory reset and nothing works.
I have made sure its not hte sim card by putting it into my old S5 and it works fine.. it currently is my phone until I figure out the Note 8.
Does anyone out there have any other suggestions?
Check your APN settings.
Check another sim card in your note 8 (friend's sim card or a new sim card (old one might work on s5 but might not on note 8)) or Take it to your carrier and let then try their sim card and see. Point is try another or different sim card!
Might to check if there is no dust or dirt in the tray or dirty sim card.
Last resort BACKUP your phone and factory reset.
Take your device to the high street retail branch of your cell provider and let them take a look at your device. They will probably reinstall the network settings on your device
So basically what was going on was that when I need to make a call, the note 8 needs to drop from LTE to H or H+, which I observed it doing on my samsung S5 and a Samsung S7. For some reason or another, the SM-N950N KT version is stuck in LTE only mode and wouldn't downgrade to H or H+ and therefore couldnt make or receive calls.
The fix? Since I bought it back in 2017, way past any warranty period - I installed Dr Ketan's ROM and effectively changing the CSC to Australia region and within 15mins all fixed!
If anyone else is having a similar problem, I was on the Kogan network [vodafone].
Thank you Dr Ketan! https://forum.xda-developers.com/ga...t/29-09-17-dr-ketan-rom-jio-volte-n1-t3681163

I know right! It was just a tablet before - had to use my old samsung s5 as a phone.
It is all good now - Dr Ketan's ROM is amazing - Loaded my note 8 with an Australian CSC and it is perfect. No bloatware, high configurable.
Hi folks,
after the last update I have a big problem: when I start a call suddently the signal goes 0 (on both SIMs) and I receive a "no network" error. After a few seconds the signals go back but sometimes I have to wait for 15 or 20 minutes to call otherwise the call drops again.
It happens even when receiving calls.
I have this problem at around 30/40% of calls I try to make and this is very disappointing because I use the phone for work and I do many calls everyday.
A user on an Italian forum had the same problem two updates ago, he told me that he solved after a reset of the phone. I'm desperate now, tomorrow it's holiday in Switzerland so I think I will do it.
NOTE: It's strange nobody on internet is talking about this problem... It's only me?
Having the same issues with this build.
I have the HK dual sim, which I flashed the SEA firmware onto last year.
I'm having to go back to my old phone until this is resolved, I have missed several calls because of it. I tried a factory reset, which seemed to clear it up for a short while, but the problem came back.
Same problem here. After the update of
51.1.A.5.159I cannot receive or place calls
I cannot receive or send messages
IF I am inside a building. The network goes from 2 bars to 0 when I try to call. If i go outside of the building the cellular network is stronger (full) and calls are going through. I suspect there's something wrong with the baseband maybe? Which is what I was trying to search for yesterday. Was wondering if the current baseband for Android 11 is new or maybe it is the old one from Android 10?
Regardless, I can wholeheartedly say that Android 11 has basically shattered the signal strenght on this device to the point of making it useless. Now I can use it as a multimedia device... weeeheeeee.... Buy a premium device they say, it will be worth it, they say. Never had this issue on any of my Oneplus devices. Shame on Sony!
(btw my phone has the international software, not the HK one. using it on one single sim- XQ-AT-51).
The italian user told me now he's fine, the problem didn't came back.
Tomorrow I have a Switzerland holiday, I'm going to reset the phone to try to fix the problem.
Thanks for answering my question, it seems I'm not the only one with this problem. It's a pity there's no more official Sony forum to discuss these issues.

Please do let us know how you get going. I too wanted to perform a factory reset but I've postponed it in case I could find some answers on the internet.

The phone is now restoring the backup from Google but this evening I don't think I will make a single call.
Tomorrow at work I will stress it (usually I make 1h of calls everyday, using both SIMs), and give you the results. Cheers!
The situation is maybe worse than before.
I don't remember if is it possible to downgrade. Xperifirm? Still works with new phones?
Otherwise I have to use my old XZ Premium because I have so many issues at work.

The thing I noticed is that the call drops when switching network from 4G to 2G. Expecially on my Italian SIM, i have a weak 4G signal in my office (1-0 bars) but I have a full 4 bars 2G signal. Before this update when I start a call you can clearly see the signal bar going from 0-1 to full 4 meaning the phone switched to 2G. After this update it was impossible to place a call from my office on my italian SIM because it fails in that 4G/2G switch.
I put that SIM in "GSM only" and I had no issues in managing calls. It's unpractical but works.
The problem is worse on my Swiss SIM (the one I use for work) that has no 2G coverage, so I leave it in 5G/LTE/WCDMA/ecc ecc and hope the best. But I see some switch happens even there ranging from 0-1 to 3 bars (I think is 4G/3G switch. I don't have 5G or 2G coverage in my office). So I can't do anything to avoid the issue, that happens randomly but it's quite frustrating
(...)Same problem on HK. Does anyone think that the problem will be solved with an update? Sony flagship haha. The gsm signal was much weaker than the former P20pro before .... 178. Now ..... disaster. I think the only asset Remaining that you can read "network unavailable" on a 4K screen
So far mine seems much better after the latest update 58.1.A.5.222.
Here's hoping it was a temporary glitch.
Please try to use only one SIM until new updates.
I have the same issues but with only one it works fine.
Do we have any news about a new update so far ?
Have a good day!
Today the 58.1.A.5.222A update arrived, I tested the phone and seems to be OK, tomorrow I will test it harder during the workday.
PS: since two weeks I was using my old XZ Premium and the 1 II was resting in the drawer. So sad. I tried to flash another firmware but I had errors on Flashtool and newflasher. Nothing worked wtf.
After a working day in my office with many calls on both SIMs (a place where the problem was at its best as wrote before) I can confirm you the update completely solved the problem.
So thanks to everybody for the support, I hope you'll also be able to fix it with this update.

"Temporary glitch" un par di balle*: 3 weeks with my old XZ Premium, and the actual flagship "Xperia 1 II" in the drawer! And resets, backups, restores, tests, copying gigabytes of data from and to the phone, hours of trying to flash other firmwares and receiving only errors...

I got the same software number and my problem still persists. Thank you for updating the thread with your findings. Glad to hear yours is working now.
Hello everyone, I faced the same issue on my device after updating to the software version mentioned by author, I've fixed the issue by flashing .280 software for SEA customisation. Original one was HK. So, now I'm able to use my phone as usual. Hope this tip will help somewho. Good luck with your devices.
I don't know how I ended up letting this issue last for so long but it has been happening for a good 3-4 months. It might have been after a firmware update, it might not. But at this point it's driving me coco-nuts.
Phone: Galaxy S21 Ultra 5G (SM-G998B/DS), using an e-sim.
Whenever I try to "actively" use my phone on cellular data (e.g. opening the Youtube app), without fail I will lose all connectivity and the "No Service" logo will show in the status bar. It takes 10-30secons to cycle back to having service, rinse, repeat. I get 2-3 seconds of working cellular data each cycle.
This doesn't happen if I don't try to "actively" use data. The phone holds service, I'll even receive Whatsapp Calls with no problem so long as I don't initiate them.
I've tried resetting network settings. I've also tried switching Network mode from "5G/4G/3G/2G (auto connect)" to the other options.
Any ideas?

It's likely a problem with your e-sim data plan. Have you tried using a normal sim?
I should've mentioned I tested it with a plastic sim from a different operator and the issue remained.
I had this same issue since Jan. A few S21U phones have it and it seems to be some kind of software + hardware issue that affects a small portion of the phones.
The OneUI 4.1 update should fix it. have you got this on your phone yet? If not you should see it soon.
Thread from the Samsung community forum. posts at the end from MattH665 is me, detailing my extremely frustrating ordeal with this issue:

Until you have the update, if you force your phone to 3G (assuming 3G isn't shut off where you are) then you might be able to get by. Mine worked fine on 3g (of course it's slow).

I had tried googling the issue using many, many keywords and was getting stumped with unrelated results.
Your "S21 Ultra reception fail" youtube video is basically exactly what was happening on my phone, albeit a bit faster to recover from the no service status.
And...... I basically got the notification for the OneUI 4.1 update around the same time I was notified of your response. The issue has disappeared altogether.
Thank you for bringing it up with the techs at Samsung. Don't know how long I could've held on to the device in this state.
As a side note to anyone reading this in the future, there was an update to the "Private Compute Services" app available as soon as the phone reboot from the OneUI 4.1 update. The 24th of March patch notes claim "operating system improvements and capabilities. Bug fixes and various optimizations.". That could also have been the fix.
Cheers.
Hello- I purchased a used S21 ultra and tested everything and it appeared to be working. Once I left and got to an area with only 4g, it turns out the 4g doesn't work. Sometimes it'll get ok download speed, but never any up. Is there any possibility it's something repairable? Any settings to check/change? First time I've ever been scammed on an in person purchase.
Thank You!
Possibly need to reset network settings.
Yeah, I've done all the recommended things to try many times. The last resort would be flashing to an older firmware, although I've never done that before and would hate to brick the phone.
So - this phone lists model as SM-G998U1 - however when I type it into samsungs warranty checker, it shows SM-G998UZSAGFI. Is this simply not a US phone with the proper bands for US?
