How to unblock notifications on Samsung C5 that are muted?

If your mobile phone always mutes automatically, we recommend the following:

1. Some machines support the automatic mute function. If your mobile phone supports this function, please turn it off. Operation: Settings-Sound-Auto Silent Mode-Auto Silent Mode-Uncheck.

2. If the sound is still automatically muted, it is recommended to try uninstalling the recently installed third-party software.

3. Back up important data in the phone and restore the machine to factory settings (Settings-Reset/Privacy/Personal-Factory Restore).

If the problem persists, please bring your purchase invoice, repair card and machine to the Samsung service center for inspection.
