Well I needed a stockish wallpaper so I could show off the phone to someone, so I tried to get the TOH ambience working, as for whatever reason the phone stopped detecting it. Not having searched about how it works, I removed the NFC tag thinking that there would be some sort of PCB underneath, but to my horror there was nothing, which means I've basically destroyed the small piece that made it work at all. I put it back on the TOH and into the phone, it doesn't work of course and it will probably never work again.
