There could be several reasons why your WiFi and Bluetooth are not working on your Samsung Galaxy A10s. Here are a few things you can try to troubleshoot the issue:
# Restart your phone: Sometimes, a simple restart can fix minor software issues.
# Check if the WiFi and Bluetooth toggle switches are on: Go to Settings > Connections and make sure that the toggle switches for WiFi and Bluetooth are turned on.
# Check if the WiFi and Bluetooth chips are enabled: Go to Settings > About phone > Hardware information and make sure that the WiFi and Bluetooth chips are listed as enabled.
# Check if there are any software updates available: Go to Settings > Software update and install any available updates.
# Check if there are any issues with the router: If you're trying to connect to WiFi and it's not working, try connecting to a different WiFi network to see if the issue is with the router.
# Reset the network settings: Go to Settings > General management > Reset > Reset network settings. This will reset all the WiFi and Bluetooth connections on your phone.
# Factory reset your phone: If none of the above solutions work, you may have to perform a factory reset of your phone. Keep in mind that this will erase all the data on your phone, so be sure to back up your important files before doing this. To factory reset your phone, go to Settings > General management > Reset > Factory data reset.
