following this guide to uninstalling and reinstalling Oculus software,
but when I go to Application Manager, it won't let me uninstall 'Gear VR
Service',...
Having a similar issue with an unlocked SM-G920F, apparently changing
the firmware can fix this problem without voiding warranties, but I
can't find a definitive list of firmwares that support Gear VR.
