With the launch of Canvas 4, Micromax introduced a completely new style of unlocking your phone. Until we had Slide to Unlock, Pin, Pattern, etc but Canvas 4 brings us something new called “Blow to Unlock”. Once you set this application as default, you just need to blow Air on your screen to unlock the phone. Very nice and cool feature. If you are having any Android smartphone other than Canvas 4 and want to get this unlocker on your phone, well it is possible. You can simply install this APK on your phone and you are done. You can download the apk from below.
