Can you get into your Home Screen? How long until this occurs?

A. Take a Screenshot:

Take a screenshot on your iPhone. See if it it seen. If so, then it is a software issue. If not, then it is a hardware issue, and you need to get this serviced. Go here: Take a Screenshot on iPhone - Apple Support

If you cannot see it, then, if Photos is enabled in iCloud settings, then go here, and see if it is seen: https://www.icloud.com/photos

B. Stuck in a Boot Loop:
