With the lack of updates of Openelec, I switched to LibreELEC on my media player. (not a S905) It has been running well with no problems.
BEWARE I ACCEPT NO RESPONSIBILTY IF THIS BRICKS YOUR DEVICE
If you head over to the LibreELEC forums, https://forum.libreelec.tv/thread-524.html There is a guy there that has created an image for devices with S905 chips.
I followed the guide & had LibreELEC running on an Android device via the microsd card.
Note, the Android device is very similar to the futeko MiniMX Android, but not bought from Futeko.
