content: Termux is the best.  Especially when you ssh into it from a real computer.    I use my super-cheap Android phone as a 4G modem, via an ssh tunnel from my laptop.  (You can also run tor, etc on the phone and connect to it from the laptop.)  This bypasses the hotspot gig limit, so my laptop has "unlimited" connectivity in the woods.  Add a gasoline electric generator, and you can be 100% productive off-the-grid.
