How to fix network issues on Samsung Galaxy Z Fold 2

1. Restart your devices

If the connection dropped suddenly, then it’s probably just a minor glitch in the device’s network system. Try restarting your device and see if that fixes the problem. A device reboot usually works by restarting all system services and eliminating any system flaws that may be affecting your device’s network system. If possible, reboot your router too and then reestablish the connection and then try reconnecting to see if the issue resolves.

This action resets all wireless features on your device thereby clearing glitches or flaws in your phone’s network system. So, try turning the airplane mode on for few seconds and then turn it off. Then, check if the network problem is resolved.

To perform Airplane Mode trick, go to phone’s Settings -> Connections-> Airplane mode menu and then toggle the Airplane Mode switch to turn the feature on for a few seconds and then turn off again.
