Nine returns?! Are you getting hit with carrier upgrade fees every time or did you buy outright sim free?
I returned my Max and got a Xs and absolutely love the size (previous phones were 7 plus and 6 plus, nice to have a smaller phone!) but the display is as warm as the Max and this one has a pink tint that my Max did not have. I can get by with color filters but the phone has crap cell signal. I went out today and had no service where my girlfriend had a bar LTE, also getting disconnected from calls in places I never did with any of my old phones. I just don't know what to do. Maybe I return this and wait for the Xr or a used X...It's so much of a hassle to drive to Apple to return & get hit with these new $30 carrier upgrade fee's on apples iUP program...
I'm just thinking maybe there will be an update to fix the cell signal issues and warm displays? I almost think it's a sensor or something software related triggering True Tone or Night Shift even though its off...
