It was scary.
My phone was laying on a table and one of my dogs knocked the table down. Landed in sand.
When I picked it up it looked dirty and I tried to clean it. Nope, was almost pierced with glass breakage spider webbing out.
I was sure the phone itself was cracked, especially as I didn’t remember that the screen protector was glass. Even talked to Apple Support about it, and they had me convinced that the screen was broken.
Friends took a look at it and convinced me it was the screen protector.
Irony: screen replacement (but limited to two incidents) is $25.00 Replacing the screen protector? Almost $45.00
