i make a remote file for the u9 / u22 and my Logitech Harmony remote (harmony setup to: minix u9 “android”)
for coreelec our libreelec
it is the same on the u9 our u22 only the key back is (temporarily) not working on the u22 in android os.
working keys are:
KEY_1 to 9
who is interested can download the file here:
you need to activate ssh in corelec and instal putty on windows
setup guide in the download map
after this you can install keymap editor.
to use the keys from 1 to 9 to open windows you are use frequently.
in my case in (full screen video)
8 download subtitles windows
4 and 6 sync subtitles
7 open video settings window
on the u22 you have to set inject bl301 set minix
so it will start corelecty after you power off from coreelec.
