Answer to "Touch IC ios 11 error"Hello everybody, Regarding the 6S aftermarket Lcds issue, today I made this test: I took a 6S phone with original Apple screen; I updated its IOS 10.3.3 to IOS 11.0.1. Then I switched the screen with an aftermarket one, Tianma brand; all worked fine, no touch screen issue; tested for many hours; then I repeated the experience with a 2nd device which was not responding, as my client made the update to IOS 11 using a Tianma compatible LCD ; I switched to original, made again update to IOS 11.0.1, then install the same Tianma compatible LCD that he used; and it worked; no blocking, also tested for many hours. Hope this will help you. Don't worry, be happy.
