Power button wouldn't click so I followed a different guide (very similar to this). I only realized now that proximity sensor wasn't working. It doesn't bother me too much, but I may try to fix it. I had to reopen it to fix my WiFi after a little piece fell out and I replaced it with aluminum foil. A small piece of plastic fell out that looks like the proximity sensor. How does it get affixed back to the power bracket?
My main problem is that my pinhole microphone (next to the headphone jack for speaker phone and audio in videos) doesn't work anymore. It gives me a hissing sound. A guy at a fix-it store seemed to tell me that it was related to the power bracket and things might need to be shuffled around because it was very unlikely it was damaged. Does the little metal square on the power bracket provide power for the microphone? Is there anything specific that needs to be touching other parts in there to make it function properly?
If you could respond to firstname.lastname@example.org I would be very grateful.
