Is the screen of iPhone 13 Pro anti scratch?

I'm going to be direct in my response. NO, iPhone 13 Pro is NOT anti-scratch and if you don't put a good quality screen protector on it, you can fully expect to see from micro to deeper scratches over time. Most all Apple Stores install Screen Protectors from Belkin, which are very good. Best Buy sells various brands of screen protectors as does Amazon. I would personally NEVER not have a screen protector on my iPhones. In fact, I install one the minute the phone is taken out of its box, before its ever turned on.

To some degree I suppose, various abrasives will damage the surface. It's certainly certainly not scratch resistant to the degree that a sapphire watch crystal would be. One still needs to be careful.

No screen is anti-scratch. Fit a tempered glass screen protector with a notch. They can be had online for a few dollars.

You're welcome.

You're welcome, good luck.
