When I finished installing the battery, I put everything back together the way it should be but I have two small problems.

Problem 1: The top of the screen doesn't sit the way it did before I opened it. It sticks out more at the top than the bottom. I'm not talking much, maybe fractions of a MM extra?

Problem 2: The screen isn't as responsive as before. When I'm typing, it sort of lags and then it catches up really fast, sort of like when they phone is "busy" and then it catches up with what you're typing. However, it's not only during typing but scrolling and when tapping the screen. It is generally overall less responsive.

Any ideas?
