On 5/26, my S22 Ultra suddenly disconnected from the network. Even though it showed bars and 5G, I was unable to make calls. Occasionally, it showed "no service" at the top and a notification that "your phone's not on a registered network, so you can only make emergency calls." After a Google search, I tried:
1. Phone restart
2. Airplane mode off and on
3. Software is up to date
4. Removed SIM, wiped down, reinserted
5. Another SIM
6. Reset network settings
7. Toggled SIM on & off
8. Factory reset
Then:
9. AT&T, 2 different stores over 3 visits - every time I was in the store, it connected. But it clearly was not a network issue, so they could only offer replacement by insurance or trade in
10. Geek Squad - offered replacement, same as AT&T
11. uBreakiFix - offered to replace parts, but stated 70% of the time, it is a software error, and the phone must be replaced anyway.
I can't find any information on Samsung recognizing the issue, which seems to be quite widespread over the past year & including S23 Ultra, and offering replacement. I am out of warranty, and my extended warranty with All State has expired.
Are we going to get a class action lawsuit? Sign me up.
I'm having the same issues on my S24. I'm with AT&T. Very frustrating when the phone won't hold onto a 4g or 5g signal and you can only make emergency calls only. Samsung needs to do something
I had similar issue with my s23. Phone was bricked after one ui 7 update. I thought it was due to the one ui update, like a software issue. I flashed the firmware to the newest version. Didn't work. I even reverted it to older versions. Didn't work either... After some research, I found out that it's likely caused by faulty USB charging board. It turns out that this is a quite common issue with s21,22 and 23. Somehow the antenna is relying on the charging board.
I had the USB charging board replaced. And it worked! Repair kits are available for 15 bucks online. It took me 30 min to replace it. Or you can have someone do it for like $100.
After the most recent updates my s22 ultra seems to have major issues connecting to service its says 5g+ with full bars, but drops calls, emergency calls only, and waiting for network is a new common everywhere, where as before I never had connecting issues, I've done everything suggested but factory reset any suggestions would be great. ( sorry if this has been brought up before I haven't seen anything as of yet with this issue)
Yup done that, they say there's no issue, because ironically when they run a test I'm at one of the few places that I connect to so of course there's no issue.
I believe I said I've done everything I can find on the subject minus factory reset, which included 2 hours at a carriers office today. Which they inturn did everything I did 2 times minus the said factory reset lol, thus I'm here asking if anyone else is experiencing the same issue after the latest updates.
