When Samsung launched Galaxy S4, one of the defining features of the new handset was air call-accept. Air call-accept is the feature that allows you to answer a call on Galaxy S4 simply by waving your hand in front of the screen. Now, the same functionality is available for other Android handsets through an Air Call-Accept app.
The app has been developed and released by a member of the XDA Developers forum. As soon as you download and install the app, the feature is activated on your Android handset.
However, to let the app detect the movement of your hand, you need to make sure that the proximity sensor is working on your smartphone. In some handsets, the sensor is activated by default. In certain cases you will have to turn on the sensor by tweaking the settings. For instance, in Galaxy S3, you can do so by going to the Motion Settings.
The basic version of the app is available for free. It essentially allows you to answer an incoming call. However, there’s also a paid version of the app which lets you perform a number of other tasks such as rejecting a call, turning on the speaker during a call and more.
Although the app is currently available, developers are still reporting a number of bugs in it, which are being fixed right now. So while you may want to try your hands on the free version of the app, don’t be surprised if it offers some minor glitches. You can get the app here.
