Internal Microphone not working.
I bought this Iphone 3G as is. The glass screen was cracked and the internal microphone is not working.
I replaced the cracked glass myself. But I am at a loss of what could be wrong with the internal microphone?
The speaker works though. I tried reconnecting the dock ribbon cable many times, but the microphone still does not work. I also used a can of compressed air to blow at the microphone, thinking since the phone was originally dropped and the glass cracked, there is a good chance dirt might've entered the microphone grill. But that didn't work either. The microphone does not register ANY sound at all. Not even in the voice memo app. Or any app for that matter, UNLESS I used the headset microphone.
I am thinking of ordering a complete new dock connector assembly, but I just wanted to know if someone had a similar problem and had it fixed and how?
This iphone 3G is jailbroken and unlocked. IOS 4.2.1
It was jailbroken via Redsn0w and unlocked using Ultrasn0w. But I don't think the internal mic has anything to do with this. The speaker works, the microphone does not. If I plug in a headset then the mic works via the headset mic.
I just received my Iphone 3G Dock assembly. Used the ifixit dock replacement guide and replaced the entire dock assembly. Put everything back together and Tada! It works! The only problem is Cable 4 which connects the Dock to the logic board. This cable unclips by itself sometimes. Have to find a sure fire method to securing it.
But the Problem got resolved when I replaced the entire dock assembly. :)
Is this a good question?
