Apple has been accused of failing to correct a ‘design flaw’ which is said to be causing many iPhone 6 and 6 Plus handsets’ screens to flicker and become unresponsive to touch. Repair specialist iFixit suggested that two chips were to blame and ran the risk of detaching from a circuit board over time.

Newer iPhone 6S and 6S Plus phones are said not to be prone to the fault because the same two chips are connected to a different component in these models.

Neil Mawston, from Strategy Analytics, said ‘there doesn’t seem to be any quantification about precisely what percentage of iPhone have been affected, so it’s difficult to tell if this is a minor or major problem. Apple customers pay a premium for their iPhones, and they expect premium after-sales service.’ (24th August 2016)
