Naomi, the Apple store does not monitor these questions. I'm not sure if they still sell the 6s plus model. You will have to call the store. If you are having problems with a 6s plus model, they msy be able to repair it but you need to take it to the store for diagnosis.
I already sold that one, thank you
not sure. You can call and ask.
