Software updated 14.5 but microphone stop working on phone and camera how to start microphone

Hello dhruhi,

Welcome to the Apple Support Communities. From your post, it appears that the microphone isn't working. We'll do what we can to help.

Try all the steps here: If the microphones on your iPhone aren't working

If you're still having issues, try backing up then updating to iOS 14.5.1: Update your iPhone, iPad, or iPod touch

Thanks and have a wonderful day.

dhruhi,

If you're still having issues and have done all the steps, the best thing to do is look into hardware: iPhone Repair - Official Apple Support

Take care.
