In the Recognition section that you saw in Figure 8, slide the Interaction Control button from Off to On so you can block areas of the screen from recognizing touch input, disable the auto-rotate feature, and keep notifications on the screen confined to the Status bar. That is, you won’t see a pop-up box on the screen announcing your new notification. You can turn this option off by sliding the Interaction Control button from On to Off.
After you turn this feature on, you can block or unblock areas of the screen from touch input by pressing the Home button and the volume down button at the same time. Then you can select the area of the screen to block or unblock in the Interaction Control screen. If Multi-Window mode is on, you’ll need to turn it off in the settings list on the left side of the screen before you can block or unblock screen areas.
That completes your tour of the Accessibility settings on the Tab 4, so enjoy exploring all of the options so you can make the Tab 4 work effectively for you every day.
