Touch issues after 7 plus screen install replacement

Touch issues after 7 plus screen install replacement

So I had this happen today with two installation attempts with two different phones and two different replacement screens. I'm putting a new screen on an iPhone 7 Plus and the screen tests fine prior to install, yet when it's fully inserted into the frame, the touch screen functionality goes erratic and is basically non-usable. The second screen I was dealing was SUPPOSED to be OEM quality (I'm having my doubts on that supplier) so I was really surprised to have any issues. I had the chance to tinker with that one a lot more than the first and the different was obvious, the screen is fully connected and everything installed on the back of it and it tests totally fine while it's outside of the frame. But as soon as it goes in all the way, it's worthless. Now, this guy, and the first, now that I think of it, had some rather significant bends in their frames that I couldn't straighten out completely. However, the original screens, once reinstalled, worked just fine so perhaps it's just an issue with some of the aftermarket screens being rather finicky. I should note that 3d touch was turned off.

"Investigate the ribben cable for naked cupper and use elec. tape on that area

Or use sth on top of connector for making sure they are in place

Third ask for refund and buy sth with garantee"

I had problems with my IPhone 7 plus after I replaced the lcd on it, it lost sound to it, phone lost its all of its vibrating functions, volume buttons stop working but worked to take a picture, front camera stoped working, etc… I taped the &&^&@@ out of everything and it solved all the mentioned issues took me some time to release so sharing this info to possibly save someone time, kindly Adam

"I had a similar issue like this. I replaced the screen on an i7+ with two different aftermarket screens from my brother. He buys cheap screens and it was my only choice because the person wanted their phone fixed that day. I installed the 1st screen and about 24hrs later, the touch stopped working on it. I assumed it was the screen and installed a 2nd screen from my brother. 12hrs later the touch stopped working again.

At this point, I ended up getting a 3rd higher quality screen from my usual supplier and the touch stopped working after about a week. A hard reset fixed the issue, but the issue came back again. I posted this as a question, and the only answer I received, was to make sure the black tape that's on the back of the metal plate gets transferred over and stuck to the ribbon cable of the new screen. It was not installed, because that black tape usually does not fit around the touch IC chip that's on the ribbon cable of any model after the i6/i6+. Basically any model with 3D touch.

I am to the understanding that that black tape has no functionality other than to simply hold the ribbon cable in place, seeing it has no similarities to grounding tape. I haven't gotten around to giving this a try, but you might want to try that and see if it helps."
