Concern About Screen Separation on iPhone 13

Hi,

I’ve noticed a small but consistent gap between the screen and frame of my iPhone 13. Out of concern, I performed a quick check and found that I can insert a piece of paper into the gap—it slides in until it stops just before the charging port.

The screen feels solid and the phone works fine otherwise, but I’m worried this could be a seal issue, which might affect water resistance or long-term durability. I haven’t dropped the phone, and it hasn’t been opened or repaired before.

I’d like to have it inspected to determine if this is a manufacturing issue or something that needs service. Please let me know what steps I should take next.

Thank you.
