Microphones not working after screen/digitizer and battery repalcement
I replaced the entire screen (new screen included glass, digitizer, camera etc) as well as the battery on my sons's 5C. Now now of the microphones are working. Everything else works cameras, home button etc. Did I mess something up? Is there a central connection that would effect all 3 microphones?? Thanks for any help
Esta é uma boa pergunta?

mics were working. I pulled apart/reassembled 3 times. I examined pin connectors with magnifying glass they look good. If all mics (bottom of phone, top front and top rear) are not working doesn't that rule out that the new screen assembly (including the 3 ribbon connectors on the new screen), i.e. the issue is somewhere in the main body of the phone. Only the front facing top mic is part of the new screen assembly. The only issue during the initial repair was difficulty removing the old battery that adhered into the phone. Both adhesive strips ripped free - so really had to pry battery out. Battery charges fine, speakers play music and previously recorded videos, but no mic to record new audio on videos (front facing and rear facing camera), no mic for phone service, no mic even if phone is switched to speaker during phone call - can hear other person just fine. I must have accidentally disconnected something?
