Display flickering or Multi-Touch Problems[touch disease] in iPhone6/6 Plus Repair cost $149,Apple say

Info! Apple has finally admitted the issue and offers to fix it
The first reports about issues with iPhone 6 and iPhone 6 Plus emerged a few months ago when many owners claimed their smartphones are affected by display flickering or multi-touch problems.

At that time, Apple did not comment anything on the matter, probably thinking that this isn't a widespread problem. Furthermore, the display flickering issue has been attributed to the fact that some users have dropped their iPhones more than once, which is why they phones started having problems.

Fast forward three months and Apple has decided that these issue aren't that isolated as it believed in the first place. Starting right now, owners of iPhone 6 and iPhone 6 Plus affected by the so-called “touch disease” effect can repair them at Apple.

Apple now offers to repair all those iPhones that present display flickering or multi-touch issues, but it turns out that these repairs won't come for free. Apple won't even touch your phone without you paying $149, assuming your iPhone's display isn't cracked or broken.
“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.”

However, if you have already paid for a service repair related to this issue through Apple or another authorized service provider, you should immediately call the Cupertino-based company for a reimbursement.
According to Apple, “the reimbursement amount will equal the difference between the price you paid for the original service to your iPhone 6 Plus and the $149 service price.”
In order to fix your iPhone 6/6 Plus you have three options: head to an Apple authorized service provider, Apple retail store, or via Apple technical support. Keep in mind that you won't be able to fix your iPhone at any of the carriers in your country.
