I guess the work from fandangos on a JRE Kodi addon for Android is known.
JRE Addon for Kodi (Android) Release
Add precompiled JRE binary, keyboard/decoder profiles
It seems to work better with the player.
Fandangos added a keyboard profile and a decoder profile to the latest JRE Addon release.
Maybe the keyboard profile is the solution for bad control of the player with the JRE Addon for Kodi (LibreElec)?
Would perhaps be possible to collaborate and troubleshoot with fandangos?
