To perform a factory reset on your Samsung Galaxy S9 Plus, go to Settings > General Management > Reset > Factory Data Reset. Confirm your selection and follow the on-screen instructions. This will erase all data on your device, so ensure you have backed up important information.
If you're experiencing Wi-Fi connectivity issues, try restarting your phone and router. Ensure your phone's software is up to date. You can also forget the network and reconnect by going to Settings > Connections > Wi-Fi. If the issue persists, reset network settings under Settings > General Management > Reset > Reset Network Settings.
