Tried all that and nothing, still works on the camera app which is weird. Should I delete the update?Welcome to iPhone Forums!
Is your iPhone up to date? The latest software for the iPhone 7 is iOS 14.6. If that’s the case, you’re not the only iPhone 7 owner with microphone problems.
For some of the people affected, restarting their device and/or resetting network settings helped, at least for a while. Maybe it’ll help in your case as well.
