@Pe_112: If you head to the Phone app > Dial *#0*# into the Keypad > Select Red, Green and Blue from the series of grey tiles, is the line visible in any of these tests? 

If so, then please head to samsung.com > Scroll to the bottom of the page > Contact us, and reach out via your preferred contact method, and an advisor will be able to arrange for the device to be inspected by an authorised engineer.
