Samsung Galaxy S 4 owners may be familiar with the the Air Call Accept feature, which allows users to answer calls by simply swiping over the infrared sensor located near the earpiece. It’s most definitely a very useful (and fun) feature, allowing you to answer calls by merely bringing the phone next to your ear, or without getting your potentially grotty hands all over the screen. Good thing is, though, you don’t need a Galaxy S 4 to do this. Thanks to the magic of proximity sensors (standard to every phone released in the last couple of years at least), you too can do this.
Inspired by the original Samsung feature, XDA Senior Member Williams.Joe developed Air Call-Accept, a free app which—you guessed it—allows you to answer calls without touching the device. As alluded to earlier, this is done by simply waving or coming within the range before the proximity sensor, meaning answering calls is as easy as holding the device next to your ear, as one usually would when speaking on the phone. When trying out Air Call-Accept, please be mindful that certain bugs may be present, as some users have reported that calls are being automatically accepted when the device is in an small enclosed area, such as the pocket or the bag.
So if you’re device is running Android versions 1.6 or newer and are interested in giving this a go, head over to the application thread for more information._________
