The newly bought vivoX6 mobile phone has the same volume, the ringing of incoming calls is loud, but the volume of short messages is low. How? Ask for help.

I suggest you try it in the following ways:

1. Go to Settings-Sound-Turn off the ringtone and try it.

2. Try changing other ringtones.

3. Enter Settings-More Settings-Restore Factory Settings-Restore all settings, try it, then reset the ringtone and set the volume to try.
