iPhone 16 pro max came with screen protector

My husband and I were so

frustrated with our new iPhone. We had a hard time typing and could not use stylus.

when I got phones I took out of box which was fully sealed, before I turned it on I put on a screen protector. Well just yesterday I needed to change the screen protector and I realized there already was one on Phone. When my husband got home I asked to

see his phone and same thing.

Not sure why it had one on but for what we pay for phone it should have one on.
