the bottom part of my iPhone 6S is unresponsive. I can't hit the spacebar and so on. But I can still tap on app icons on said part. Initially I thought it was a software issue so after a couple of reboots I decided to factory reset my phone. And it didn't help at all. Now I'm stuck in the set up screen and I'm unable to tap the button. I might give the Quick Start option a try but I don't have any other Apple devices with me. I took my iPhone to the Apple store and they told me the sensor is malfunctioning and I need to have the screen replaced and told me they can't help me set up my phone unless I got it replaced. I'm looking into some cheap third party screen replacements but right now I'm just trying to work on what I've got.
