Use Android as Microphone
Have you ever needed a microphone, but did not have one available? Have you ever searched for a way to make a cheap wireless microphone? Needless to say, you can use your Android device as a microphone. There are two ways that this can be accomplished. The first is through traditional cables, and the second is through additional software. If you want to use your Android device as a microphone through USB, Wifi or Bluetooth, then skip to the second method.
Android Boost Speaker Volume
Let’s face it. Even at max volume, sometimes the speaker on your phone just isn’t loud enough (Yes, I’m looking at you Nexus 5). However, you could digitally raise the maximum volume that the speaker allows itself to go to. This will require a rooted android device and could run the risk of damaging your speakers if you go too high, so be warned.
