I've been messing around with libs,and libaudio, which is supposed to deliver sound, is open source on the google nexus, I fiddled around with it a little bit and got the sound from the earpiece, (I will upload a video and/or a sample I promise). However, sound quality is very bad, the sound is like "hehehehehellllllloelo" instead of "hello". Sound is too choppy and very noisy. Didn't test GPS yet but I'm being positive.
Now, to test other libaudios, if somebody here knows which are open sourced and which aren't please post, I'll not have to look through all of them.

P.S. This is just a testing thingy, I'm no big coder.
