Turn on Magnify mode
You can use Magnify mode to enlarge the information on your BlackBerry device screen. You can zoom in to or zoom out
from the screen, even if you use an application that doesn't normally support zooming.
On the home screen, swipe down from the top of the screen.
Settings > Accessibility.
Turn on the Magnify Mode switch.
The information on the screen immediately appears larger.
To move around the magnified screen, use two fingers to move the screen in the direction you want to go.
