Smartphones are the opium of the 21st century... And worst of all, they
will become the new identity cards. For example, until recently I could
do transactions with my bank through its website. But now it is
mandatory to have a smartphone and download an application, of course
proprietary.

Anyway, termux and Emacs, without a physical keyboard, is torture. I
usually connect a compact mechanical keyboard that I have for my laptop.

By the way, I've noticed how easy it is to write Elisp functions that
call Termux commands from Emacs. I recently wrote this to send SMS (you
can enter the phone number directly or choose a contact saved in BBDB
data base, if you use BBDB). To see the list of contacts it works better
if you use also some completion framework like ivy or helm:

(defun send-sms ()
  (interactive)
  (save-window-excursion (bbdb ".+"))
  (let* ((tlf (if (yes-or-no-p "Enter a contact: ")
		  (let ((record (bbdb-get-records "Contact: ")))
		    (aref
		     (car (aref (car record) 5)) 1))
		(read-from-minibuffer "Phone number: ")))
	 (sms (read-from-minibuffer "Texto del SMS: "))
	 (cmd (format "termux-sms-send -n %s %s" tlf sms)))
    (call-process-shell-command cmd)))
