To access the Accessibility features on your Android device open the Settings app
In the Settings app, select Accessibility from the list.
On the Accessibility screen, scroll down to the Display section and select Display size.
On the Display size screen, adjust the slider at the bottom of the page. The preview pane will now resize to show you how your new setting will look. You can also slide the preview pane to the right to see how your setting will look in other parts of the operating system.
Note: we have written these instructions for devices running the standard version of the Android operating system. You may find some minor presentation differences if the manufacturer has customised the theme.
