Samsung galaxy note 20 ultra having problem with network after software update

Members_Onl4kfS — Sat, 25 Jan 2025 21:54:06 GMT

Hi Community,

I have updated my samsung galaxy note 20 ultra since then I have a problem with the network operator selection, mobile phone unable to find network. Tried to reset network settings, try to add access points, tried changing network operator selection but did not work. Same SIM car is working on iPhone no it seems it's not a sim card problem.

Some how I can't turn off network operator selection to manuall and getting error . Could someone guide me here ?

It seems like your Samsung Galaxy Note 20 Ultra may have a software issue or network configuration problem. Here are some steps you can follow to try and resolve the issue:

1. Check for Software UpdatesGo to Settings > Software update > Download and install.Make sure your phone is running the latest software version, as updates often fix network-related bugs.2. Verify Network Mode SettingsGo to Settings > Connections > Mobile Networks > Network Mode.Ensure it is set to LTE/3G/2G (Auto connect) or 5G/LTE/3G/2G (Auto connect) depending on your carrier.3. Reboot into Safe ModeRestart your phone in Safe Mode to see if a third-party app is interfering with network settings.Turn off your phone.Turn it back on while holding the Volume Down button until the Samsung logo appears.In Safe Mode, try selecting the network operator manually again.If it works, an app might be causing the problem. Uninstall recently installed or suspicious apps.4. Reset APN SettingsGo to Settings > Connections > Mobile Networks > Access Point Names.Tap the three dots in the top right corner and select Reset to Default.If your carrier requires specific APN settings, enter them manually.5. Force Manual Network SelectionOpen the Phone app and dial *#*#4636#*#* to access the testing menu (if available on your device).Go to Phone Information > Set Preferred Network Type.Try selecting LTE only or the appropriate network type.6. Check SIM Card and SIM SlotEnsure the SIM card is seated properly in the slot.Try inserting the SIM card into the other SIM slot if your phone has dual SIM support.7. Factory Reset (Last Resort)If nothing works, back up your data and perform a factory reset:Go to Settings > General management > Reset > Factory data reset.After resetting, check if the problem is resolved before restoring your apps or settings.8. Contact Samsung or CarrierIf the issue persists, it could be a hardware problem or a bug specific to your phone’s firmware version.Contact Samsung Support or your network carrier for further assistance.

Let me know if any of these steps help!

I am also experiencing the same issue since the last update, it was working perfectly before. Tried most stuff except factory reset, which is very time consuming having plenty of apps to be reset again for security purposes. Not expected such from Samsung they should have tested it well enough before deployment of last few updates for the 2020 series.

I thought I was alone with this problem but I guess not. I even changed sim providers twice!!!! Sim tray/connection to internals is also secure I double checked!!

This problem is getting really really frustrating. I get no service and data now. Only vary rarely does it pop on.

Has anyone heard from Samsung about this software update issue?

One Ul version: 5.1

Current version: N986BXXSGHYD1 / N986BOXMGHYD1/N986BXXSGHYD1

Security patch level: 1 April 2025

Dear Paul,

i sent the error trough the Samsung member app as you suggested, now i hope to receive a solution.
Local SAMSUNG service center (Italy, Siena, Marzocchi) failed to repair. SAMSUNG Italy support said there is no cause effect link and offer 25% price discount for a new mobile (!) .

Any updates on this? also sent a feedback. it has been like this for months. unbelieveble.

been forced to move back to an S9..
I believe im going with an Iphone next time.

Paying 1200++€ so i can be in the same exact situation within the next 3 years?

or less! because this is the second time it happened to me. First time during warranty, they've replaced the Sub-PBA board or something like that. Ridicoulous. Sick of Samsung to be honest.

Even the watch had been an absolute disgrace:
Spotify app in the watch its a joke. If you need to go for a quick run and want to hear music, you have to do 50 thousant things: make it offline, etc etc etc. Not a very usefull app..
NOW THE FUNNY PART IS THAT IT'S NOT EVEN WORKING ANYMORE ... im really disappointed at Samsung..

That's the fact, i really thought they had solved it but maybe it concerns too few people.
