Chosen Solution

Got a 6S on eBay, it sorta works. The problem happens when I am scrolling. As I gently drag my finger up and down, the list of items slides a little bit but then something gets the signal to select one of the videos or emails. So as I try to run down the lists videos and emails are constantly popping open and it makes life hard. The problem seems a little intermittent though. Do I need to think about replacing the screen or should I just open it up to see if the cables are mis-routed? Thanks!

The cables may be partially disconnected but realistically, the screen is bad…which probably explains why it was being sold on eBay. IMO, you should just return the phone and get a refund. The problem with buying phones on eBay is that you have no idea what this phone has been though and this one most likely has had a rough history. If you did want to fix it yourself, then check out this guide to see if you are up to it.
