The company wrote in a service document:
Apple has determined that some iPhone 6 Plus devices may exhibit display flickering or Multi-Touch issues after being dropped multiple times on a hard surface and then incurring further stress on the device.
If your iPhone 6 Plus is exhibiting the symptoms noted above, is in working order, and the screen is not cracked or broken, Apple will repair your device for a service price of $149.
Although Apple never uses the phrase, this is a fix for "touch disease."
The problem occurs when certain iPhone models - the iPhone 6 Plus, in particular - have an issue with an internal part and the display flickers, displays a grey bar at the top, and becomes unresponsive to touch.
The issue was fairly widespread, according to our readers, who emailed us frequently after we covered the issue in October. Most people were frustrated that Apple, although it appeared to be aware of the issue, would still charge out-of-warranty customers $329 for a fix.
Apple says it will reimburse customers the difference if they already paid the $329 to get thier iPhone 6 Plus fixed. Frustratingly, Apple is still claiming the issue is caused not by an engineering defect, but rather because the phones were "dropped multiple times on a hard surface."
You can get your iPhone 6 Plus fixed at Apple retail stores and authorized service providers.
