iphone 7 speaker microphone not working for calls or voicemail...

Hi rakeshd,

Thanks for coming to Apple Support Communities for help today with your iPhone 7 speaker and mic. It sounds like you aren't able to hear on calls or be heard.

Have a look at this article: If the microphones on your iPhone aren't working. Have you tested the mic in the Voice Memos app? If it isn't working, service will be required.

For hearing on a call, please see: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker. It could be that the receiver needs to be cleaned.

Have a fantastic day!
