Lets hope not but I upgrade every year on a payment plan with T-Mobile so likely won't affect me if it does
So far it's much smoother and faster than any Samsung I've had
Samsung slows their devices too, or they end up that way.
One guy tried and bought multiple Note 8's and they all lagged.
At least with Apple you can turn the throttling setting off now.
With Samsung, I don't even think it's an option, unless someone knows differently.
