After replacing the screen twice, my iPhone 5C clicks in weird places.

So I run a small town repair business at my high school. It's only existed a few months, and on my 3rd device, an iPhone 5C, things are going waaay wrong. And I'm struggling a bit. Care to help?

I am not hasty or impulsive at all when it comes to repairs. I have an ifixit toolkit, a magnetic project mat, ischlack, and everything one would need to do a repair effectively. When I do repairs, I have iCracked's full length replacement video as well as iFixit's guide open (mostly for screw sizes). It takes me about 2 hours to do a repair. So when I gave the device back after only some basic testing, and the poor girl reported the phone having an unstable touchscreen, I was really nervous. I took it home and tested it, and sure enough, the thing was a mess. It kept scrolling all over the place, the screen straight up stopped working at minute intervals, and browsing through apps like the notes section or instagram were impossible - jerking, rapid movement, the whole shebang. I took it apart again and examined the pins, and nothing seemed out of the ordinary under my magnifying glass.

iFixit, my parts supplier, graciously sent me a replacement after 1 call.

Now, I've just finished the second screen replacement, and things are better, but unacceptable still. In spurts, the screen works beautifully, like new. But within a few seconds, it has now decided to click random apps, go completely nuts and pull down search every 2 seconds.

This is a paying customer. My buisness will shut down if I have to borrow a few hundred dollars for a new phone. I simply wouldn't be able to pay it.

Will a hard reset help in this situation? Could it be the software is rejecting the new hardware?

Please, please help.

EDIT: Also, I should mention that oddly, the screen resets this spasm right after you lock it and unlock it again.

I also just tested it with a timer - spasms can take 5 seconds to a minute and a half to occur.

Have you tried cleaning the connector pins for the digitizer cable as well as the terminal?

Would I go about doing this with rubbing alcohol, or just a cleaning cloth? I am careful not to touch anything I'm not supposed to, including the digitizer pins and terminal, and have only cleaned it with a cleaning cloth.

Rubbing alcohol would be perfectly fine to use, just make sure it is 90%+, so you minimize water content. I prefer to use individually picked swabs, as it allows me to control the amount.

kevincellservices, I go with either a bad connector on the cable or the connector on the board. Those connectors do not have metal ends and deform incredibly easy. That causes the contact pins to either lose connection or not making connection. Check those very, very closely.

A glitchy screen is most commonly caused by a poor cable connection. Make sure when you're connecting the ribbons to be slow and steady. Sometimes clicking one side in, then the other and finally pressing down in the middle makes the difference.

Use a magnifying glass to check that none of the pins on the phone/display are damaged. If nothing seems out of place, it just needs some finessing to guarantee a solid hold.

Also, be sure the connector itself isn't bent. Sometimes forcing the cable in will deform the shape - carefully bend it back and again, try placing it in one side at a time.

Usually bad LCD that has been sent out or bad connection.

Does the original screen work fine? If so then it is the replacement screens.

I had the same problem with mine and read up that it was due to grease that gets on the screen as your typing and clicking things. To fix mine I bought a cheap plastic screen protector and put it over the top. Now it works fine!
