Hi.

If you are using Android you already have a full Linux environment.

Instead of using SSH Clients to connect to SSH Servers, you may give a try to termux.
You can install web servers, traverse your android, create files using vi among others.

Another good thing is that the app can aquire "lock" from the status bar to prevent exiting in case you have running processes.

To install termux open Play Store on android and search "termux"
