There were a couple of times when Samsung Pay blocked all payments until an update was applied and the change log had nothing to do with payment functionality but with other useless & unrelated stuff like "better notifications" "better deals". NOTHING, absolutely NOTHING about a security issue, a flaw or a hole that was being used to steal money.
I havent had too many issues with Android Pay but still its the same issue ... instead of a simple swipe and go, and my ability to use my money in anyway I want and I am not at the mercy of an app developer who is acting as a gatekeeper to access my money so he/she/it can control what I need on my phone / my device to use my money whenever I want so they can push their agenda that has nothing to do with me using my money. no thanks.
thats not even including the additional cut the app provider takes and increases my price effectively. I'd rather pay one middleman.
Credit Cards dont need to be "fixed" or "solved". As a customer, its easy to use, widely accepted and my risks are covered 100% by the issuer. I cant say the same for phone payment methods.
