Note:
Editing #AltText with #Tusky on #Android doesn’t work.
Use #Fedilab or the computer's browser version instead.

Also:

Due to repeated crashes on #Android* when doing #AltText, this is now my standard procedure:
Post w/o AltText and then edit and repost immediately afterwards.

#Fedilab has never been up to date with #Samsung OS updates and even gives this as excuse in its error messages. Crashes frequently, too, but has more features, like #translate.
