Problems with GSM network on Galaxy S22 Ultra

[Brochs]

I received my Galaxy S22 Ultra 512GB, Exynos version, over a week before official release date. As I was using the phone I discovered several bugs with my unit, screen blackouts, occasionaly freezes, conversations loosing sound, phon not reachable over GSM network even if my signals was good. I decided to wait until official release date to see if new software would be released. On the 25th Samsung released new firmware for my phone, and I did a complet factory reset after new firmware was installed. I am now on firmware S908BXXU1AVBF and fresh phone setup.

My screen problems seems to be gone, but GSM network issues are still there. Several times I have been made aware of that my phone can not be reached by callers, even if phone is showing signals. Solution, reboot. Turning on and off flightmode did not help. Also I am experiencing sound dropouts during calls, call is not droped but sound oth ways are lost, duration 10 - 15 seconds. Also when making a call the phone uses much longer time to set up the call than other phones I have had. Calling my self from other phones give simular results, setting up phone calles to my Galaxy S22 Ultra take much longer then calling others.

Have been in contact with Samsung support, but there is no help to get there. Try this, try that, over and over again. I am starting to loose my patients now, and its impossible for me to have a phone I dont know if I can be reached at, and when I manage to set up a call, sound is lost several times during the call.

S22 Ultra since one week: conversations end unexpectedly, sometimes after 4 min, or 7 or 13 minutes.

Sometimes though, calls do not drop.

For professional calls, this is unbearable.

Is there any roundabout?

Please provide us with a fix ASAP 😩

One question... all phones are the 512 GB version? I know people with the 256 version without problems and seems that everybody here as me have the 512.

I have a 512 GB Ultra version and I have no problems, Exynos

[John-CH18]

I have a 256 GB Ultra version Exynos 2200 8 -Core.

 i have 256 GB version and after the 1st april update absolutely no problems

I have Exynos 256GB Ultra and still have the issues after April update. Calls go "silent" randomly on my side and the person I am calling can her "white noise" for approx 5-15 seconds then the call resumes, well that's unless the person I am speaking with has hung up

For context, I have no issue on my S10 testing with the same sim, and its a replacement sim I got from my provider.

So since the update last week my call problems have got worse not better. Before a restart every morning would clear the call problems most days but now even that doesn't work. Calls take a minute or more to connect, incoming and outgoing calls have no sound for me and whoever I'm trying to speak to. The lock screen freezes seemed to have stopped, as have the audio and video lag... But the phone still randomly restarts whilst watching videos sometimes...

I've been telling everyone I know what an expensive piece of junk this phone is, think I am going to start contacting all the tech media outlets and point them towards this thread, see if we can get some traction on this because this is unacceptable. S21 ultra 512gb Vodafone UK.

Ultra expensive. Ultra buggy. Ultra useless.

Just an update: Since the replacement of the motherboard, ribbon cable and USB module a few weeks ago, I do not have any issues at all. Everything is working fine.

This is just me, but here is my logic on the S22 series problem:  Since a random sampling of people around the world  {both with Snapdragon and Exynos chips} are experiencing these problems (even after some have replacement phones) the odds of the problem being hardware related seems not likely.  What are the chances people in 8 diffferent countries all got bad replacement S22's?  Therefore I'm back to thinking the problem is that the phone software cannot properly handle conflicting cell tower signals, whether 4g or 5g.  Yes, switching a sim to an older phone seems to get great signal, but those phones don't have the cell tower software problem the S22's have.    If it's not the sim cards, and it's not the hardware since phones have been replaced, but still it's not ALL the S22's in the world, then the people here who are experiencing the problems happen to live and/or work in an area with conflicting cell tower signals that the phone cannot negotiate.  I am guessing the only way to prove this theory is to have somebody who has zero signal problems on their S22 to travel to an area where we are experiencing the problems and see if their phone then goes whacky too.  So, yes the problem with the software may be global, but people traveling to a random different area may just assume they have bad signal in that location, or even if they move there they assume they've moved to a bad signal area.  I believe that all S22's have a problem negotiating conflicting and/or interfering cell tower signals in specific geographic locations, where other phones do not.  And the problem is even heightened for people in conflicting 4g / 5g areas.  And, it may have something to do with the new Galaxy Ultra 22's being real "Signal Beasts" as reported by many in the electronics media.
