Only happens on Saturdays and Sundays ...

I have been observing for months, my samsung pay always fail on the white color terminal, i have no issue to wave using physical card on the same terminal though,  anyone experienced the same?

Same here,  still Samsung Pay. Tried the steps but still the no update

SWallet abit annoying for me, some terminal cannot accept (white colour), after tried only know. I'm trying to be patient for the point sake.

Really don't know why in my case, black colour terminal 100% success rate, white one some can some cannot, normally after 3rd try then I will have to pull out my CC. Not sure what's the different.

Because of this, i don't even dare to use my Galaxy Watch to pay.

That's an interesting question - haven't thought about it at all. Taken from https://www.samsung.com/my/samsung-pay/freq...stions/rewards/
