The Acer Iconia Tab A100 is a tablet with a 7 inch, 1024 x 600 pixel display, an NVIDIA Tegra 2 dual core processor, and support for Android 3.2 Honeycomb or Android 4.0 Ice Cream Sandwich.
Unfortunately some users have noticed that the tablet has a pretty lousy built-in microphone. So if you want to use the Iconia Tab A100 for voice or video chat, voice recording, or anything else that requires a mic you might want to use an external microphone — or crack open the case, void your warranty, and replace the internal microphone.
Xda-developers forum member Metallica 4 Life took the latter approach.
Once you pry off the plastic sides of the device you’ll need to remove 5 screws and then pry apart the case.
If anything breaks, you’re probably out of luck because there’s no way this is covered by a warranty, and good luck finding replacement parts.
But if you do managed to open up the tablet and aren’t scared of using a soldering iron, you can find the rest of the instructions for replacing the mic at the xda-developers forum.
By the way, you can pick up a refurbished Iconia Tab A100 from Buy.com for $190.
