Yup - I did the same thing… The top corner of the encasement was slightly bent from when I had dropped the phone and where the screen cracked originally. I didn’t notice it right away and when I went to “snap” the screen back down into place during reassembly, it wasn’t quite a perfect fit, and when I tried to press it into place, I cracked the new screen. Note to self - “check for small dents in the encasement and try to fix before trying to tighten down the screen”. The new cracked screen is still better than the one that I was replacing. I feel so dumb. Chalk it up to a rookie mistake I guess. Hopefully this little write up saves someone else from making the same mistake.
