If your device started having signal issues after the One UI 8 update (2025.11.24), it’s likely a software-related bug rather than a hardware problem. Here’s what you can do:
Restart the phone – sometimes the update needs a full reboot to stabilize the network. Reset Network Settings – go to Settings → General Management → Reset → Reset Network Settings; this refreshes mobile data, Wi-Fi, and Bluetooth connections. Toggle Airplane Mode – turn it on for 10 seconds and then off to force the phone to reconnect to the network. Check for carrier settings update – sometimes carriers release small updates after a major OS update. Backup and Factory Reset – if nothing else works, a full reset can remove lingering update glitches.
If the issue persists after all this, it’s likely a One UI 8 bug, and you may need to wait for the next patch from Samsung or contact your service center for a software reflash.
