What should I do if the 4x telecom version doesn't ring?

If there is no ringtone during a phone call, it is recommended that:

1. Please check whether the phone is in mute or vibration mode. Operation: standby interface-pull down the screen top curtain-find the sound icon-click the icon to switch to sound mode.

2. Adjust the ringtone size: Set-Sound-Volume-ringtone (incoming call volume) and slide to the maximum.

3. Check whether there is sound in the setting menu. If there is a sound, it is recommended to try to change other ringtones.

4. Restart the phone.

5. If your mobile phone supports the function of turning off all sounds, it is recommended to go to Settings-Auxiliary Functions-Turn off all sounds-uncheck it.

6. If it is invalid, please back up the information (contacts, text messages, pictures, etc.). ) in your phone, and then restore the factory settings.

If the problem still exists, please bring the purchase invoice, maintenance card and machine to the Samsung service center for professional after-sales engineers to help with the inspection.
