iPhone 6 touch problems? The gray flickering is an epidemic


If your iPhone 6 or iPhone 6 Plus stopped responding to touch, you’re not alone. Many iPhone users are reporting the loss of touch combined with a strange flickering gray bar at the top of the display.

The problem has been around since the launch of the phone, but didn’t manifest until recently because the phones are getting older, according to a recent report from iFixit. It’s being called “Touch Disease” because it has become such a widespread problem.

iPhone 6 “Touch Disease” is said to stem from Apple’s design of its logic board for this particular phone. This board is home to most of the circuits that make your iPhone work, including the processor, storage, and touch controllers.

Over time, shock from normal use or drops slowly strain the connectors on the two integrated circuits (IC) that control touch on the iPhone 6 and 6 Plus. Once the ICs become disconnected, touch becomes intermittent or stops working completely, often accompanied by a gray flickering bar at the top of the screen.

So why is this happen only to the iPhone 6 and 6 Plus? Apple didn’t use a substance called “underfill” to help support the touch ICs, according to independent repair specialists like Jessa Jones of iPad Rehab and Louis RossmannThe reason we haven’t seen this in older handsets is because Apple has used in previous iPhone models.
