IF YOU own an iPhone 6 or iPhone 6 Plus have you experienced a problem with the functionality of the touch screen?
Plenty of Apple customers have - and they're certainly not happy about it.
A number of people have complained about the diminishing sensitivity and spotty functionality of the touchscreen on their iPhone 6 device as it gets older. With an unresponsive touchscreen the phone effectively becomes frozen and can't be used properly.
The problem has been dubbed "touch disease" and according to the blog ifixit.org which coined the term, iPhone repair technicians are getting an increasing number of customers experiencing the annoying issue, which seems to be more common in the larger iPhone 6 Plus version.
Aside from the obvious symptom of a frozen screen, touch disease is easy to diagnose because handsets will display a flickering grey bar at the top of the screen.
The reason for this is that the two tiny "Touch IC" connectors, which translate the tapping and swiping of your fingers on the screen into a machine input, become slightly detached from the phone's logic board.
The result is often a progressive, and seemingly erratic, deterioration of touchscreen function.
Apple has so far declined to officially acknowledge the issue but angry customers in North America have taken things into their own hands.
A class action lawsuit has been filed in both the US and Canada complaining about the issue and even accusing Apple of covering it up.
