Upgraded to an Xs from a 7 on the Sprint network back in Dec. , my reception where I live became completely spotty. I was missing important calls and texts. Don’t know if it was Sprint or the modem thing, but I have had Sprint for years. Decided to sell the Xs and go for the att iPhone 8 deal. Been missing the smaller size of the 8 ever since. Happy except for that damn home button. Really feels awkward now.
