Android: You know that awkward moment after you take a phone away from your ear and can’t hear anything while you find the speakerphone button? Auto Speaker works in the background to eliminate this issue for good.
Once the app is installed, it will use your proximity sensor to automatically toggle the speakerphone when you move the phone to or from your ear. An on-screen button will also allow you to disable the app for individual calls, and you can customise your speaker’s time delay so it doesn’t trigger if you’re only moving your phone from one ear to another.
This is a great idea if you take a lot of calls while driving, since you won’t need to take your eyes off the road to find the speakerphone button. Unfortunately, it won’t automatically start a call in speakerphone mode if the phone isn’t near your face; it will only kick in after you take it away from your ear the first time. Still, it’s a handy utility, and it's free at Google Play.
