I have a p8p as well and am a sucker for contactless pay.
I have a samsung android watch which costs like $50 second hand to get around the wallet not working on graphene.
I dont really care anymore about gathered metadata that much. I was more black and white earlier, but nowadays I just try to minimize the cloudification instead of being completely against it.
I choose my battles, and being against google wallet isnt really worth some effort from my side.
Could you maybe resfresh my memory a bit and share a few previous signal hacks? Thanks
