You can easily determine if you have a hardware or software issue. A reliable method to confirm a screen or other hardware fault is to take a screenshot when the fault is evident - and then review the captured screenshot image...

When reviewed, if the line(s) are not present in the screenshot image, then you have demonstrated that you have a hardware fault that sooner or later, may become sufficiently severe that repair or replacement of the iPhone are the only options. If unexpected line(s) are visible in the screenshot, then something other than hardware will be the cause.

Note: The screenshot image may need to be viewed on a different device/screen. Reviewing the image on a different device will ensure that the image does not coincide with screen defects if present.

If the test indicates that a hardware fault a visit to the Genius Bar at your local Apple Store is recommended - where the technicians will be able to test and assess your iPhone. This will likely inform your next steps:
