The screen protector itself fit perfectly on the surface of the phone. Very easy to install without bubbles. While there was no difference in handling the phone, it has a terrible flaw, namely it did not allow the phone to recognize the fingerprint, which made certain applications difficult to use. Since these specific ones do not work with facial recognition, I had to remove the screen protector every time to verify the fingerprint, etc. I believe that a protective screen should function as if it were the screen itself. I used it for 1 week and unfortunately threw it away. If fingerprint usage is not an issue, then it is a good purchase; otherwise, no.
