Wouldn't it be great it USB WiFi adapters worked out of the box with Android? Smartphones I believe are as close as we are going to get to cybersecurity inspired tricorders. Long battery life and portability are two good reasons to investigate this further. Just imagine Kali running nmap, tcpdump, wireshark on your phone.

Here is a developer who was able to get some USB WiFi adapters working with Galaxy Note 2.

He also developed native android airodump and airmon apps that doesn't require chrooted Kali or Backtrack to run.

We need to support these developers to create cybersecurity apps that works on android.
