Change timing controls
If you need more time to respond to a notification or messages that are visible only temporarily, you can
adjust the time before they disappear:
1.
Go to
Settings
> Accessibility.
2.
Touch Timing controls.
3.
Adjust settings:
•
There are two basic gestures for controlling your phone: touch and touch & hold. You can adjust the
amount of time before your touch on the screen becomes touch & hold. If you find that you
accidentally touch & hold when you intend to touch, choose a longer delay. Use Touch & hold delay
to select short, medium, or long delay.
•
If messages that ask you to take action are disappearing too quickly, touch Time to take action
and choose a longer time. Not all apps support this setting.
•
If you're using a connected mouse, you can set the cursor to click automatically when the cursor
stops moving for an amount of time. Touch Autoclick (dwell timing) and select the amount of
time.
Use external switch or keyboard
If you're unable to use a touchscreen, Switch Access lets you control the phone using external switches or
keyboard keys to select items, scroll, enter text, and more.
To use Switch Access, you must have one of the following:
•
An external switch. USB or Bluetooth switch devices send keystroke signals to your phone.
•
An external keyboard. Standard USB or Bluetooth keyboards can work as switch devices by assigning
one or more keys to actions.
