Need help with setting up iPhone?

Hi, the bottom screen of my iPhone's unresponsive to touch because apparently the sensor is malfunctioning. I did everything from restarting to doing a factory reset. Now my phone is stuck in the set up screen and I can't press the lower buttons. I don't know if Quick Start would work, but I don't have any other apple devices with me at the moment. I took my phone to the Apple store and they told me they can't help me with setting my phone up again unless I replace my screen. Right now I don't have enough funds for a screen replacement so I might just have to try and work with what I've got.

Added (1). I have an Iphone 6S btw,

Added (2). If there's some way I could set up my iPhone with my computer please do tell me right away

Go F your mother. LOL
