The Indian mobile phone manufacturer Micromax has introduced a new unlock feature called “Blow to Unlock” to its recently unveiled Android smartphone Canvas 4. You can unlock the phone by just blowing air on the screen. If you wish to have this impressive unlock feature to your Android phone, an XDA forum member ported it to work on other devices running Android 4.0 and later.

This is an original blow app extracted from the canvas 4 ROM and will work on all Android devices running Android 4.0 and later. To install this app on your device, follow the below given guide.


First of all, if you have enabled a Pattern or Pin lock to your device, you should change it to “None”, because we are going to change the lock type on the device. For that, go to Settings > Security > Screen Lock and then select the “None” option.

Now download the MUnlock.apk file on your device (Download link at the bottom of this post).

Install the app just like any other APK (You can use any file manager for that). Also, don’t forget to enable “Unknown Sources” from Settings > Security and tick Unknown Sources. Otherwise, the app won’t install.

Now, go to your app drawer and click on the MUnlock app icon. Tap the lock icon so that it is locked to turn on the “Blow to Unlock” feature.

Blow to Unlock is a highly advertised feature of Micromax Canvas 4. We just need to blow air or shake to unlock the phone – a cool feature. If you are bored with your current locking options, try Blow to Unlock! [Source and Download XDA]
