The case esq buy a iphone 5s at a good price because it does not work aq id the touch. She sold it q q told me he broke the screen and through the insurance is changed in ktuin (q guess screens are original by the agreement they have with apple q), but since then the id does not work touch (supogo q you will also have changed the button). I read around here q can link the new button to the processor refreshing, but I have already done and still no go. Any suggestions? It is not a must for me, but if you can return to work, the better.
