That's a very encouraging level of communication. Along with the responsiveness around the delayed bootloader unlocks, it seems really impressive (at least to me, coming from a post-Lenovo Motorola device, where entreaties to the OEM are ignored entirely). I will be astonished if they actually manage to resolve even half that list though - particularly the Widevine issue - I'd understood that was not practicable via software update, from the discussions around OnePlus devices
