I have an iPhone 6 Plus that has intermittent touch screen issues. It’s due to the batch of iPhone 6 that have a slight bend and the logic board is the main cause. See this thread for more details: touch screen intermittent, sometimes has white lines on picture Whenever the touch stops working I can usually just press really hard on the screen where the connectors are, and it comes back. It seems like the connectors just come loose, but it happens really often. Is it a bad idea to use some sort of conductive glue on the connector to make it stop coming lose? Something like this: https://www.radioshack.com/products/radi… I realize this is a very permanent thing and would pretty much ruin the phone if it doesn’t work, but I’m at a point where I’m going to salvage the phone anyway if I can’t get this fixed.
There are shops that can fix this problem for you by replacing the touch IC chips. They are the problem, not the connector. I promise your plan will ruin the phone, don’t try it. The cost is usually about $150 but it’s much better than replacing the phone. Look up iPad Rehab, they’re a good company that performs this repair
This is touch Ic related. You basically have two tough ic chips on the other side of the board behind the cpu and screen/camera connectors. Due to a faulty job in manufacturing…..hint hint Apple’s work…..these can come loose from a good solder connection. Dropping is usually the case. We’ve done a few in our store…if you don’t have a lot of experience they’re a pain in the butt. Basically replacing the two chips (meson and cumulus) and redoing the solder joints should fix this. Strongly recommend not letting just any store try this as you can damage much more on the board trying. iPad rehab is definitely my first recommendation.
