Fenix 7 pro solar screen protector

I owned Pro solar for two weeks, put tempered glass on it, but it looks normal. This is weird? Is that foil or glass?

Hello
it is tempered glass

Glass not installed correctly

So should I not use screen protector?

This is not a sapphire version..

Everyone decides for themselves whether to install glass or not. I install because 2 or 3 glasses a year break. This is already the 3rd Garmin since 2019. I have Chinese glass in the photo and it is almost invisible.

Thank you :)

Had a matte glass on my 6pro (no sapphire) and was very pleased. Unfortunately, the manufacturer has slipped my mind.
For my 7pro I have therefore ordered a matte film and then a matte glass. Both were not satisfactory. Somehow the display looked blurry.
Now I have a crystal clear glass on my 7pro (no sapphire), it protects but I am not as happy as with the matte glass on the 6pro.

Thank you
