don't!!!
I'm currently using one, the pictures come out with heavy glare.
and image quality is not as sharp as lenless.

meanwhile I'm currently ordering a thicker case,
once she arrives I will throw this protector.

u can also use finger grip ring, the phone will slightly thicker...
but at least the back phone is not touching the surface.

Ask future80 yourself this questio before buying a protector for camera.
Have you ever own previously a smartphone?
Do you seen your previous smartphone camera lens scratch before?
These lens are gorilla glass and is not easily scratch. also you seldom get to scratch it

🤦🏻‍♂️gorilla glass or sapphire both will scratch la...
they r scratch resistant and r not scratch proof.

as long as there is sand or any hardness level (mohs) material is higher than them... it will scratch
