All of my bank apps work fine on graphene. I'd switch banks if their app stopped working, not stop using graphene. I stopped using Google wallet, I don't miss it enough to justify using stock android. For other apps, I just put them in a separate profile that has good play installed/configured. It really wasn't bad. The worst part is wiping your phone to install graphene the first time, I prefer just to get a new device for it so I can move stuff over
