Hi,
I have a Japanese P8 purchased from Japan. I'm testing out the stock ROM on it now, but I'll be switching to Graphene soon.
One thing I'd like to know before switching is if I would be able to take advantage of the Felica chip that comes with Japanese phones that allow me to use my phone as a transport card in Japan. The only thing I found online about this topic was this now-closed Github issue, which suggests that it is indeed possible:

Still, I'd like some first-hand testimonies that it works fine before making the switch, if possible. Thank you.
