The campus network mobile phone can't be connected.

Samsung mobile phones are generally checked and processed according to the following steps:

1. Turn off the wireless network and search again;

2. Check whether the entered wireless network password is correct.

3. Confirm whether other devices under the same wireless network are normally connected and whether the wireless network has set connection restrictions.

4. Due to equipment compatibility problems, some wireless networks with Chinese names or special symbols may not be able to connect. It is suggested that the wireless network name be changed to English.

5. Please check whether the router connection is normal (unable to connect the cat), then turn off the phone and restart the router and try to connect again.

6. If all the above operations fail, 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, please take the purchase invoice, maintenance card and machine to the service center for inspection.
