I have had this problem with several different iPhone 5Cs. None of the iPhones are liquid damaged but i have had a few where the screen is just erratic a few hours after changing it. I have tried screens which I know 100% worked before but the customer still comes back and says that the screen is erratic. I’m tearing my hair out! Is it a software issue?
Are you using an anti static mat? I have never had that issue and I always use one and ground myself. It’s also very possible the screens you are using are just going bad very quickly. I would try getting higher quality screens first because I would bet that’s really the problem
