Strange problem with the microphone
The problem occurred about a week ago. When making calls I can't talk or hear. I read that a lot of people could just use speaker and everything would be fine but my speaker icon stays gray and the iPhone doesn't let me use it. I tried testing the microphone in Voice Memos ,but just like the speaker icon, it was grey and didn't let me use it.
I don't know does this matter but my headphone jack stopped working just when the mic did.
P.S. It probably happened when I brought my phone with me on the tennis court and a wind probably threw sand into the microphone.
Thanks in advance!
