Galaxy device Interaction and Dexterity Enhancement features

Assistant menu: Displays a fixed menu with common controls and gestures like navigation buttons, swiping, an on-screen touch pad, and more. You can edit the menu to include your frequently used buttons.

Voice Access: Control your device with just your voice. You can use voice commands to launch apps, select buttons, swipe on the screen, and type. 

Note: This feature is currently available in English, French, Italian, German, and Spanish.

Answering and ending calls: Choose how you would like to answer and end phone calls. For example, you can have a caller's name read aloud to you and press the Volume key to answer.
Note: This setting may not be available on tablets.

Interaction control: Keep the device focused on a single app by blocking interactions from other apps and areas of the screen, like the navigation bar buttons and the keyboard.

Touch and hold delay: Set the time threshold for when a continuous touch is registered as a touch and hold on your screen. You can customize the time as well.

Tap duration: Set the amount of time the screen is touched until it is recognized as a tap.

Ignore repeated touches: Turn this on so your initial tap is recognized and taps that follow are disregarded. A time limit can be set for how long the extra screen taps are ignored.

Auto action after pointer stops: Choose the delay time for an automatic click when using a USB pointing device.

Sticky keys: If you have a USB keyboard attached, modifiers like Shift and Ctrl will stay pressed until another key is pressed so you can enter keyboard shortcuts one at a time.

Slow keys: Choose a time delay for how long a key should be held until it recognized as a key press.

Bounce keys: Set a time limit for waiting until a key is pressed a second time.
