I bought my wife the XS and myself the XS max on release day, my Max has been amazing with no problems, but unfortunately I can’t say the same for my wife’s XS. She has continuously had problems. The phone becomes unresponsive all the time, runs fine sometimes and slow others, and when it does run slow and is still unresponsive you can’t turn it off by using the volume button and power button you have to do a reset by pressing both volume buttons and then pressing and holding power button. The phone was doing this when on IOS 12 and just updated to the newest version of IOS 12 and the problems continue? Plan on calling apple in a little when she gets home with the phone to try and see what is going on but has anyone else had problems like this with their XS?
