Some observations:
Termux has scrolling issues with Claude's tui and rendering, so it jitters and rescrolls a lot of text when you show/hide keyboard, and you are unable to scroll up in terminal while Claude is rendering text.
Termux has native Android text selection and smooth touch scrolling. The Android Terminal does not, so you can not use touch to change selection.
Android Terminal's touch scrolling is slow (but stable) so it is cumbersome to scroll through terminal text
