Troubleshooting a Vertical on an iPhone:

I. Start with a Screenshot:

What happens when you take a screenshot? Do you still see this error, when view in (i.e. in the Photos app)? If so, then it is an issue with the iOS, if not, then it is a hardware issue, and you should get this serviced. Go Here:Take a Screenshot on iPhone - Apple Support

II. Get this Serviced:

If this is not shown in a screenshot, then get this serviced. You have a one-year, out-of-the-box, limited-warranty with this. So, see if it can be fixed, and if it would be of no cost to you (if found to be faulty device).
