My iphone screen is clean but when ever i open an app that can be scrolled up in down. The phone keeps scrolling in one direction over and over. It is like I have ghost. Can anyone help?

Does this occur at the particular app or like all of the apps?
Try to force restart your iPhone.

If force restart doesn't resolve an issue, then you have to restore your iPhone to factory settings, set it up as new to exclude a software bug.

If after all these steps your screen still doesn't behave, schedule an appointment at a Genius Bar or the nearest Apple Authorized Service Provider.
