Small crack creates awful looking bubble

Easy to install. Fit my lg x charge ok. All the holes are in the right places. I would like it better if it was 1 to 2 millimeters wider and taller for an exact fit to my screen but it works. The big problem is the one I installed has a small crack at the bottom which creates a bubble that looks awful. It doesn't go up the screen far enough to affect phone use so I left it on and got used to it now it doesn't bother me that much but I am reminded that it is cracked everytime I look at my phone.
