go to the 'pair controllers' screen, hold share and the ps button for 5 seconds(or until it flashes 2 then 2 back and forth) it'll show up. I had problems with mine timing out at first, and square is accept and x is back, so that's weird. it's usable on emulators. if it times out on you you can try plugging it into a phone charger and pairing it while it's plugged into a phone charger. I did that both times I paired mine, so maybe it helped?
