Microsoldering specialists are seeing a surge in iPhone 6 and 6 Plus devices with a common hardware issue known as 'Touch Disease' - a flickering gray bar at the top of the screen and an unresponsive touchscreen. Repair pros say the problem stems from a design flaw related to the touchscreen controller chips on the logic board, which can crack over time due to the phones' bendable frames.

Why it matters

The widespread nature of the Touch Disease issue raises questions about Apple's product quality and customer support, as the company has reportedly refused to acknowledge the problem or offer free repairs. This could lead to a class action lawsuit if Apple doesn't address the issue proactively.

The details

The root cause of Touch Disease is the two touchscreen controller chips, known as the U2402 Meson and Cumulus U2401 chips, which can become disconnected from the logic board over time due to the phones' flexible design. Replacing the touchscreen doesn't fix the problem, as the gray bar eventually appears on a new screen too. Skilled microsoldering technicians can replace the faulty chips, but Apple's Genius Bar is not equipped to make these specialized logic board repairs.

  • The iPhone 6 and 6 Plus were released in 2014.
  • Repair shops started seeing a surge in Touch Disease cases in 2015.

What they’re saying

“This issue is widespread enough that I feel like almost every iPhone 6/6+ has a touch of it (no pun intended) and are like ticking bombs just waiting to act up.”

— Jason Villmer, Owner, STS Telecom

“[Apple] doesn't tell customers they can get it fixed at an independent service center. They don't offer repair of it at all. The only option that Apple offers to people who encounter this problem is 'Would you like to buy a new iPhone?'”

— Louis Rossmann, Board Repair Expert

What’s next

Repair experts predict the Touch Disease issue will eventually lead to a class action lawsuit against Apple, forcing the company to address the problem with an extended warranty program.

The takeaway

The widespread nature of the Touch Disease problem in iPhone 6 and 6 Plus models raises serious questions about Apple's commitment to product quality and customer support. The company's refusal to acknowledge the issue or provide free repairs has left many users frustrated and forced to seek out independent repair shops to fix their devices.
