A reader turned us onto an app that appears to have been around for quite some time yet hasn’t really received much attention. It’s called Speaker Proximity, and it allows your phone to automatically toggle between speaker and ear piece during a call by using your phone’s proximity sensor. I played with it during a couple of calls on my Galaxy Nexus today and it seems to work pretty well.
The app is not in the market, but you can pick it up through its Google Project page. Let us know what you think!
