The black outline restricts you in placement.
If it "finds" the mobile phone case, you cannot lower the protective cover further, it will hide the front camera from you

I bought it for the poco m4 pro but it doesn't fit. It is larger than the screen by about 1 millimeter all around, causing it to protrude and come off when you put on the case. Unfortunately, both that I bought are going to be thrown away.

Excellent application and quality, but I wanted to know how you evaluate it while placing it on the wrong phone. Also, its job when the phone falls is to break itself and not the screen!

It is not good for the poco M4 pro, it is slightly bigger than the screen so when you put a case on it, it peels off and creates bubbles

Apart from making a few bubbles, which could also be my fault, it cracked completely after the first good drop from a low height. Okay, get a cheaper one if that's the case.
