Xz premium low volume

[langsammer]

Translation via Google Translate:

Hello everyone, my problem is that the volume is significantly lowered when it rings even if it is in the display at most. If reboot works two days and then I do it again, I did a software repair with a companion PC that went well for ten days, some suggestions?

Buongiorno a tutti, il mio problema è che si abbassa notevolmente il volume quando squilla anche essendo nel display al massimo. Se riavvio funziona uno due giorni e poi lo rifa, ho fatto riparazione software con pc companion è andato bene x una decina di giorni, qualche suggerimento?

This looks like one of your apps is acting up. Start troubleshooting by restarting your phone into safe mode, this will disable all installed 3rd party apps. If the problem is resolved then one of your installed apps is causing this issue and you have to figure out which one. Start by uninstalling those apps you installed recently.
