Microphone problems on iphone 7

Hello, today i was checking my social media and when i wanted to make a vocal message my microphone died. Now i can’t make any videos, register any message ( even if is snap, messenger or whatsapp). However, i can’t even make a call because the person who’s talking with me can’t hear absolutely nothing...idk what to do, i restarted my phone, reboot it from basic settings, clean the dirt from the microphone... nothing helped. Any advices or maybe the cause of the problem? Thank you a lot!
