Apple has confirmed a major flaw in its iPhone 6 Plus units. Tagged as the "Touch Disease," this hardware malfunction causes flickering display or flickering bars and multi-touch issues as some users complain of iPhone 6 Plus being unresponsive to touch inputs.

In response to this issue, Apple has launched a repair program for the affected iPhone 6 Plus.

"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," stated Apple in a press release.

"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," Apple added. Pricing offered by Apple authorized service providers may vary.

Since Apple does not acknowledge any flaw in the design of the iPhone 6 Plus, this issue would not be covered under warranty. For users who have already paid for a service on their 6 Plus, Apple will contact them through Apple or an Apple authorized service provider for reimbursement if they were charged more than $149.

iFixit, a popular DIY repair website believes that the error arises when the chips handling the touch input lift away from the iPhone's main circuit board. A contributing factor is when the chips are located at a point where the iPhone 6 Plus can experience more flexing in comparison to the rest of the handset.

Users who experience multi-touch issues may bring their iPhone 6 Plus to a participating Apple service provider. The unit will be examined prior to any service to verify its eligibility for this program and working order.

This repair program is applicable only to iPhone 6 Plus and not to other iPhone units.
