Chosen Solution
I recently bought a phone on eBay that had all the usual symptoms of touch disease -screen would be fine then go unresponsive about 5 minutes after use and would only respond after turning off and on - so I watched a few videos that showed using sim cards on the connectors in order help the screen connectors make contact with the logic board better. This worked for a few hours, and then it was back to square 1, but now whenever I try to turn on the flashlight it just flickers once. Before the screen would still be unresponsive at times but when the screen worked and you toggled flash it’d turn on as usual, but now the flash just flickers. Does anyone have a solution to these problems?
Touch Disease is a common failure on the iPhone 6 Plus. At first, the phone will typically develop intermittent touch control failure. For some phones, a gray/white bar starts appearing at the top of the screen. Twisting and applying pressure in certain spots sometimes allows touch control to work for a short period of time, but eventually, the touch interface ceases to function entirely. This is colloquially known as Touch Disease. You can look at my profile for a link to a blog article on Touch Disease or search the web for more info. The current best practice on repairing Touch Disease on the iPhone 6 Plus is to solidify the M1 pad (which is the LCM_TO_AP_HIFA_BSYNC line). That pad tends to lift, partially or totally when removing Meson. To date, this has proven to be a permanent repair. Look for a repair shop that can do micro-soldering repairs to properly diagnose your problem.
Hi so sorry to hear that your phone has the touch disease. As a shop we don’t recommend repairing it when it has the touch disease. You might be better off getting a phone from swappa.
