What should I do if I always can't hear the mobile phone message reminder?

If SMS ringtones sometimes appear, I suggest you:

1. Try to set the built-in ringtone.

2. Try to uninstall the recently downloaded and installed third-party software.

3. Try to restore the factory settings after the important data of the mobile phone is backed up.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee certificate and mobile phone to Samsung service center for inspection by engineers.

If there is no prompt tone when receiving software information such as WeChat /QQ, I suggest you:

1. Check whether the message has sound.

2. Adjust the notification volume and system volume: Settings-Sound-Volume-Adjust the notification and system ringtone.

3. If there is a "notification" switch in the slide of the notification bar on the screen top curtain, please turn on the "notification" switch.

4. Check the sound function in software settings such as WeChat /QQ.

5. Try to change the software versions such as WeChat /QQ.
