Phone has a mind of it's own after screen replacement
I have replaced many iPhone 7 screens now but I'm having a high ratio of phones coming back to me because of issues with the touch after the replacement. I've just been contacted by another customer saying that the screen has a mind of it's own, pressing button on it's own etc.
I'm buying what I consider to be good quality screens, certainly not cheap nasty ones. I'm installing correctly and testing before I give back to the customer (with the customer present) and all works great but within 24 hours they develop issues.
Can anyone offer any advice/solutions.
Is this a good question?
