Few hardware issues have been bothering iPhone 6 users more than the Touch Disease. Touch Disease comes with symptoms such as multi-touch issues with gray bars at the top of the screen, flickering screen, and Touch ID malfunction. It can make your device hard to use or even render it unusable. It seems to be endemic to the iPhone 6 generation, and especially iPhone 6 Plus.
What Causes Touch Disease?
It depends on who you ask. People have been linking it to the iPhone 6 Bendgate design flaw – the device can bend under pressure, which can damage the connection between the touch screen’s internal hardware and the phone’s logic board. This makes sense.
Apple, however, who has acknowledged the Touch Disease as a hardware issue, has another version. According to them, Touch Disease isn’t so much a manufacturing issue as the result of a device being “dropped multiple times on a hard surface and then incurring further stress”.
What this means is that Apple won’t cure your iPhone of its Touch Disease for free. You’ll have to pay $149 dollars to get your device fixed, provided that it is in working order and the screen is not cracked or broken. What’s more, Apple will repair only iPhone 6 Plus devices that are within their first 5 years after their retail sale.
But is there a cheaper option that doesn’t involve sending your device to Apple? Some users have said that simply bending their iPhone can alleviate the Touch Disease, but only temporarily. This isn’t a reliable fix nor a safe one, as it can put further stress on the logic board and other parts of your device.
The DIY Touch Disease Fix
There is a better, more reliable cure for your device, but it involves taking your phone apart and tinkering with some very sensitive components. It’s not for the fainthearted. What’s more, it may cause permanent damage to your device if you’re not extra careful from start to finish.
So should you try it? The truth is that for most users just sending their device to Apple is far more convenient. But if that’s not an option for you, and your device is out of warranty – and the Touch Disease renders it unusable – you don’t really have much of a choice, do you? You might as well try the steps below before getting a replacement.
Here’s what you’ll need:
- Five-point screwdriver
- Spudger tool
- A bit of adhesive tape
Once you have these, follow carefully the steps below
- Power off your iPhone.
- Remove the screws on either side of the dock.
- Remove the five screws in the top right corner of the battery.
- Use the spudger tool to disconnect the four cables from the board.
- Take out the camera.
- Disassemble the rest of your phone.
- Take out the battery.
- Remove the logic board and flip it over.
- Peel off the soft cover over the Touch chips. It’s the only cover, so you can’t miss it.
- Don’t touch the chips with your finger or you’ll short-circuit your device.
- Place the folded piece of electrical tape on the sensor.
- Put the soft cover back down.
- Put the logic board back into the phone and reassemble your device.
