What should I do if Meizu's ringtone is small?

Meizu ringtone can only be used in "Settings-> Sound and vibration->; Volume ".

If you can't adjust the volume by pressing the volume button of your mobile phone, I suggest you check:

1, try to restart the phone to see if it can be restored;

2. Confirm whether the mobile phone has permission to open the ROOT system. If yes, it is recommended to upgrade the latest firmware and clear the data after backing up the mobile phone data.

3. If there are only a few functions or applications, pressing the volume button cannot adjust the volume, which is a software problem. It is recommended to uninstall and reinstall. If there is a problem with the system's own function or application, please back up the mobile phone data and try to clear the data;

4. If the volume button is depressed and does not rebound after being pressed, it is recommended that you take the purchase certificate, back up your mobile phone data, and then go to a nearby authorized maintenance point for maintenance or fill it out and send it to Meizu official website for quick maintenance.
