If you want to know how to enable USB debugging mode in Android 4.2 and higher, this guide will show you exactly how to do that.

The following steps work on all Android devices running Android 4.2 and higher. That includes Nexus 4 [3], Nexus 10 [4], Nexus 7 [5], Galaxy Nexus, and any other device.
