I’m fixing my friend’s phone. I changed the broken screen, and for that I had to remove some connections and parts related to the mic. Now the phone works well otherwise, and even the mic works while using video camera, video calls and such, but on normal calls it’s completely mute. Now there’s few questions that pop in my head. Like, is there two mics, one for video calls, and one for normal calls? If yes, then the other mic could either be broken or not connected. Or which connections inside the phone are for the mic/mics specifically, so I could check them out. I don’t know if this has anything to do with my problem, but it would seem, that while I glued in the new screen, I forgot to remove a cover plastic from the other side. As far as I can guess, it only affects the cooling properties a bit. But there was plastic in the mic hole, and I removed it. Didn’t work though. So if you guys have any suggestions, please shoot. Thanks.
From my past Xperience (Experience) from fixing Sony Xperia Z, Z1, Z2, Z3 phones. I can confirm that there are two microphones inside the Sony Xperia Z3. One is together with the headphone jack and the other is together with the long black ribbon cable that is connected to the power, volume up + down. In this case your bottom microphone is probably damaged then you tried to pry it up. You will need to buy another microphone + volume up + volume down flex cable to fix this problem. You can buy it from eBay here: http://www.ebay.com.au/itm/OEM-Sony-Xper…
For me the flex changing is not helping, the mic keeps mute…So I wonder if there is a fuse or something that could be the reason, and if it is a fuse, where are the microphone ways on the motherboard? Thanks….
