You can often confirm this by performing a "pinch test", where you gently squeeze the area near the top of the phone to see if the lines change.

Repair Your Display

Repair costs in 2026 vary depending on your warranty status and iPhone model. If you have AppleCare+, a screen replacement is typically a flat fee of $29. Out-of-warranty repairs at the Apple Store can range from $129 to over $329 for the latest Pro Max models.
