Iphone 13 edge is too sensitive

Use the Apple leather magsafe case or any case that offers some shielding of fingers from the glass.

No.

If you would like such a feature, let Apple know here:

Hello allan_hansen,

Thank you for posting in the Apple Support Communities. We see you have a concern about your iPhone display sensitivity, and we have a link that may help. Check out the suggestions below If the screen isn't working on your iPhone or iPad:

"If your screen is too sensitive or responds intermittently to touch

1. Restart your iPhone or iPad.
2. Make sure that your screen is clean and free of any debris or water.
3. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.
4. Remove any cases or screen protectors.

If part of your screen doesn't respond, responds intermittently, or responds even when it's not touched, contact Apple Support."

Kind regards.

but Apple spent a lot of time snd money getting the screen right to the edges.

I would visit a Genius Bar in your nearest Apple Store

This is NOT helpful. Is there a way to reduce the size of the touch window? Just holding the phone will cause it to think I am tapping the edges.

I did suggest an accessibility feature allow custom adjustment of the size of the sensitivity window to allow for holding the phone without the edges being so responsive.

I have the leather apple case
