Use touch accommodations on iPhone
If you have trouble using the touchscreen or buttons, you can change how iPhone responds to your touch.
Use touch accommodations
Go to Settings > General > Accessibility > Touch Accommodations.
You can configure iPhone to do any of the following:
Respond to touches of a certain duration: Turn on Hold Duration, then tap or to adjust the duration (the default is 0.10 seconds).
To perform swipe gestures without waiting for the specified hold duration, tap Swipe Gestures, then turn on Swipe Gestures. You can choose the amount of required movement before a swipe gesture begins.
Ignore multiple touches: Turn on Ignore Repeat, then tap or to adjust the amount of time allowed between multiple touches. Then, if you touch the screen several times quickly, iPhone treats the touches as one.
Respond to the first or last place you touch: Choose Use Initial Touch Location or Use Final Touch Location.
If you choose Use Initial Touch Location, iPhone uses the location of your first tap—when you tap an app on the Home screen, for example. If you choose Use Final Touch Location, iPhone registers the tap where you lift your finger. iPhone responds to a tap when you lift your finger within a certain period of time. Tap or to adjust the timing. Your device can respond to other gestures, such as drags, if you wait longer than the gesture delay.
Choose how iPhone responds when you press and hold the side or Home button
Go to Settings > General > Accessibility > Side Button (iPhone X and later) or Home Button (other models).
Choose Siri, Voice Control, or Off
Adjust 3D Touch settings
On models that support 3D Touch, you can control the sensitivity of 3D Touch or turn it off.
Go to Settings > General > Accessibility > 3D Touch.
Do one of the following:
Choose Light, Medium, or Firm sensitivity to adjust the amount of pressure needed to activate 3D Touch. Light sensitivity reduces the amount of pressure required; firm sensitivity increases it.
Turn off 3D Touch.
Adjust Haptic Touch settings
On iPhone XR, you can adjust the amount of time needed to activate Haptic Touch when you use a touch-and-hold gesture.
Go to Settings > General > Accessibility > Haptic Touch.
Choose Fast or Slow.
To test the setting, touch and hold in the timing test section.
