Magnification gestures work similarly to the full-screen magnifiers, which allows users to zoom in and pan the whole screen to get a closer look at screen content.
Enable magnification gestures. Go to [Settings] > [Additional Settings]> [Accessibility] and enable [Magnification Gestures].

• Quickly triple-tap the screen to zoom in and out. The triple-tapping does not work well on the keyboard or on the navigation bar - if you have the magnifier running while the keyboard is shown, only the area above the keyboard will be magnified.

• Drag two or more fingers across the screen to pan across the screen.

• Pinch your fingers together or apart to adjust the zoom level.

Turn the magnifier on temporarily. Triple-tap the screen and hold the third tap.

• Drag one finger around the screen to move the view.

• Lift the finger to cancel zooming.

• Quickly triple-tap to exit.

* Pictures, settings, and paths might differ from those of your phone, but these won't affect the description in this article.
