Can not change Korean(Hangul) with right ALT key
Full keyboard has language switch key but a lot of keyboard support Right ALT key to language change.
Other programs works fine with Right ALT key to change language. but only Word for Android detect it with just ALT key input and can not switch language with simple keyboard . Yes ofcause SHIFT+SPACE works for language switch in Word for Android but I hope you support switch language in common way. Thank you.
