A serious hardware fault appears to be affecting a large number of iPhone 6 and iPhone 6 Plus handsets, with users complaining of unresponsive touchscreens and so–called ‘grey bar of death’.
This flickering bar appears at the top of an iPhone’s touchscreen and eventually leads to the handset not registering any presses or swipes.
Worryingly, tech experts believe that this isn't an issue with the touchscreen itself, but rather a problem with two of the touchscreen controller chips tucked away inside the phone.
That makes it an issue which is very difficult to fix.
Apple does not allow its in–store Geniuses to make such complex repairs, meaning it’s down to third parties to try and make sense of the issue.
An investigation by iFixit has found that hundreds of iPhone 6 and iPhone 6 Plus are going to unauthorised shops in order to find a solution.
For its part Apple is said to be aware of the problem but has yet to offer a fix, at least according to disgruntled consumers on the company’s discussion boards.
Word is that Apple staff say they have seen iPhones with the ‘grey bar of death’ regularly, but can only advise customers to buy a new device.
Experts say claim that if you’re an iPhone 6 Plus owner you’re almost certain to experience touchscreen problems.
However, Apple has not yet commented on a story which looks set to run and run.
