what Did you choose in Harmony setup? Flirc Kodi? Média center PC? With Flirc kodi the back button doesnt work in android also fast forward and rewind and power button...

Ha, ha. I knew this question was coming next.
From memory I used the Media Center PC one in the Harmony online software.

BUT, and now this is very important, you must assign a Unique command to EVERY button (leave out the power one) on the Harmony remote control, even if some of them do not make sense at this stage. Every button must be programmed and saved in the Harmony Software.

Then go to the Flirc App, and use the Full Keyboard setting. Now cross reference with these Kodi Keyboard Controls:

Program the Flirc App using the Kodi Keyboard Controls. You can use all the buttons on the Harmony Remote as each one has a unique IR command.
This is how to custom map the full Harmony remote to your liking, you get full Kodi keyboard control now from your Harmony remote. Out of the box it does not work properly until custom programmed.

Will try but I didn't understand the part to assign each button a different command. Is this the default key mapping? Or I have to change duplicates? Also the power button works? Thank you for your help!!!!
Edit: backspace works in android? I have a blutooth keyboard and pressing backspace didn't return to kodi. Sorry all the questions but I'm lost here
