[ Guide ] How to get on-screen navigation keys on Android

Some of the Android devices , like those of Micromax , Samsung out there are provided with hardware keys for navigation at the bottom , whereas some of them like Motorola , Sony have on-screen navigation keys instead of hardware touch-sensitive keys.

However , on-screen navigation keys are intrinsic in Android. So , even if the device does not have on-screen keys , it can be switched by using a small edit.

However , this is achieved by editing the build.prop file , which lies in the /system folder. So , we need root access .

Procedure :

> Download build prop editor from Playstore

[ NOTE : Do not use any other editors ]

> open the application and grant it Super User permissions.

> now , scroll down to the end of all the code.

[ NOTE : Don not edit anything else ! ]

> add this line :

qemu.hw.mainkeys = 0

> Save the file .

> Reboot !
