If you are a newbie to Linux systems, don't worry. If you have worked with Linux systems before, this shouldn't be a big deal.
Instead, all you get is a command-line shell where you can execute commands.
Termux doesn't give you a Graphical interface. Launch Termux on your phone and update and upgrade the system using the command below. Enable the Hacker's keyboard, as shown in the image below. Launch the Settings app on your phone and locate the ' Manage Keyboard' option. It also supports multitouch as the keyboard is based on AOSP Gingerbread soft keyboard. It comes with Arrow keys, Tab keys, Ctrl keys, and Esc keys. Unlike your standard Android keyboard, the Hacker's keyboard brings the keyboard's functionality on your laptop to your phone. Install Hacker's Keyboard by Klaus Weidner, as shown in the image below. You can easily download and install the APK file from the Nethunter Store website.
The Nethunter Kex application will enable you to access the Desktop Interface for Kali Linux on your Android. We downloaded Termux from F-Droid for this post. The play store version for Termux no longer receives updates, and you will most likely run into errors when using the app. Even though Termux is readily available on Google Play Store, you are highly advised to download Termux from F-Droid or GitHub.
