Open Touch Accommodations settings if not already open: Settings > Accessibility > Touch > Touch Accommodations.
When Touch Accommodations is on you can use the following touch features. Note: You can edit these features when Touch Accommodations is off but you won’t be able to use them until you turn Touch Accommodations on.
Adjust the amount of time you need to touch the screen for, before a touch is recognised.
You can adjust the length of time in which multiple touches are counted as a single touch. This is useful if you tend to touch the screen a few times in quick succession when attempting a touch gesture.
This setting is useful for users whose fingers tend to move when they touch the screen.
