Why can't my mobile phone connect to the Internet?

If the phone can't connect to the wireless network, we recommend that you:

1. Confirm whether other devices under the same wireless network are connected normally, and eliminate network problems.

2. If other devices can be connected, please check whether the wireless network password entered is correct.

3. Try to forget the network operation and reconnect. Mode: slide down the top screen-press and hold the WLAN icon to enter the wireless network setting interface-click on the name of the wireless network that failed to connect and don't let go-forget the network and search for the connection again.

4. If it doesn't work, please restart the phone and the router respectively and try to connect again.

5. Check the system version of the equipment and upgrade to the latest version.

6. If you still can't connect to the wireless network, it is recommended to back up important data (contacts, text messages, photos, etc.). ) and try to restore the factory settings.

If the problem still exists after the above operation, please take the purchase invoice, maintenance card and machine to Samsung service center for inspection.
