Screen won't close tight after reassembly
I've done some fixing on my iPhone 5, and followed the iFixit tutorial for that. I have reassembled my phone, after replacing the power and audio control flex cable, which means a lot of parts, including the logic board. Anyway, everything works fine now, but the device isn't closed tight enough, so the screen, on its upper part (near the power button), is protruding about 1.5mm up. I am aware that I should fit the screen in an order such that I first fit the upper part of it and only then the bottom, but once I fit the bottom, the upper part goes up a mm or so.
It's weird that once I fit the lower part of the screen this happens, because I never disassembled anything in the lower part of the device such as a speaker or anything, not even a single screw there was ever touched.
Please help. :)
