I went into the Apple Store because my iPhone 6 screen was beginning to separate from the casing in the bottom right corner. Rather than wait for the screen to fail I took a proactive approach and took it in. The Apple Store replaced the device under my AppleCare+ warranty. I took the phone home and everything seemed fine. Now today the touch screen is no longer responding on the new device. I've tried a complete restore twice on the phone back to iOS 9.3.5 and the issue still persists. My question is what should I pursue at the Apple Store? My guess is they will suggest some kind of screen repair, but should I push for another replacement? I hate these refurbished as new replacements as they seem to have many problems themselves. Any advice?
