I have an idea for a razer product and app:
The Razer Liaison
(the word liaison meaning link)
The app would allow to use your razer nexus/kishi as a wireless controller that you could use for a ps5/xbox/pc
The product would be a small connector thing that you could put in place of where your phone would go; it would make you razer kishi/nexus look like the average gaming controller. It could either be powered by batteries or a wire. It would turn your razer kishi/nexus into a wireless/wired controller as well
If you do end up making this which you probably won’t, please can you give credit to me, Seb
