Samsung smart remote

Recently bought a shiny new samsung television and now have the smart remote that comes with it controlling kodi on my nvidia shield. My problem is that longpress of select button doesnt bring up context menu (holding down seems to send pulses which keeps pressing select over and over again instead of a down signal). I’ve tried to remap different buttons on the remote using keymap addon but it doesn’t recognise the button presses. Anyone encounter same problem or have any ideas?
