I installed a T-Max Huawei P30 Pro liquid screen protector. I never installed a liquid screen protector before. The kit seemed quite decent. After succesfully installing it, it says to rub off the excess glue with an alcohol wipe which I did. Had some extra glue on the edge of my phone left. The problem is that I noticed some black rubbery thing coming off as well. I think it's the adhesive of my phone. I had to cut it off with my scissors. Now it looks like this: https://imgur.com/49I3sNE

What's the chance that I ruined my P30 Pro's waterproofness?
