Touch Screen Sensitivity

Hi sametozden,

Thanks for contacting Apple Support Communities!

We understand that you'd like to adjust the sensitivity of your iPhone screen, correct?

If so, you can adjust the sensitivity of 3D & Haptic Touch in the Settings as outlined here: Change 3D or Haptic Touch sensitivity on your iPhone

"How to turn on 3D or Haptic Touch

1. Open Settings and tap Accessibility.
2. Tap Touch.
3. Tap 3D & Haptic Touch. Depending on the device you have, only the 3D Touch or the Haptic Touch option might appear. For 3D Touch, turn on the feature, then use the slider to select a sensitivity level. For Haptic Touch, choose a touch duration speed, then tap the image to test your setting."

If your display isn't responding to touch, you can follow the steps outlined here to help isolate this behavior further: 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."

We hope this helps you.

Take care!
