Sometimes my microphone does not work until I restart my device.

Translation via Google Translate:
Al. Day I restart my phone several times because then the microphone is locked and I can not hear who calls me or I can not record audio. What I can do?

Al. Día reinicio mi teléfono varias veces pues sin más el micrófono se traba y no me escucha quien me llama o me es imposible grabar audios. Que puedo hacer?

I used Google Translate to find the meaning of your message. Kindly post your future questions/feedbacks in English so we can assist you, this is an English based forum.

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.
