I guess that it has been discussed before, but I can't seem to find a fix for the problem on my iPhone 6S 128GB Silver. I finally got a great device without dead pixels and clicking noise from the back cover - had to go through five devices. BUT now I experience unresponsiveness after unlock with Touch ID or password. It happens when the phone has been 'sleeping' for a few minuts. When unlocked it just hangs for 2-5 seconds before I can actually use the phone. Has anyone experienced this - and is it software or hardware related? If I disable Touch ID and password the problem is not present.
