iPhone 6 Mic intermittent issues during speakerphone
I repair phones for a company. Someone brought back their phone for the mic not working while on speakerphone. After testing, I can get the mic to work on speakerphone SOMETIMES, but if I switch back to normal mode and then back to speakerphone again immediately (basically double tap the speakerphone icon), the mic will still not work.
I thought it may be the charger creating issues (I have no idea at this point so I'm trying everything). And while testing charging WHILE on speakerphone I found that sometimes if the speakerphone mic isn't working, and then I plug in the charger, the mic immediately starts working.
I'm BAFFLED. Help?
