Hey I just ran across this on the internet, you might want to check this out- it is called Kali Nethunter. It is a version of Linux loaded with hundreds of hacking tools that can be installed on your cell phone! With this you can hack and do penetration testing using your cell! I want this, I will be downloading it right away! It is totally free and can be downloaded online! https://www.kali.org/docs/nethunter/
