That is actually genius.

My old phone is 10 years old

Props to you. That’s some value you got. I got 5 out of my last one with Lineage and thought I was doing well.

They allow you to see dust buildup which I unfortunately discovered on my last phone starts to cause lots of little micro scratches over time.
