How to zoom any where on your android

Introduction :

Enable "Magnification Gestures" and Android will zoom in on anything you want (except the keyboard and notifications bar), whether the app allows for it or now. It's easy to implement too. Just triple-tap any part that you want to magnify, and then pan with multiple fingers. Pinching adjusts the zoom level.
There's also a shortcut if you use this feature often, as Google puts it in the app itself:
You can also temporarily magnify what's under your finger by triple tapping and holding. In this magnified state, you can drag your finger to explore different parts of the screen. Lift your finger to return to your previous state.
You can zoom in on your favorite Instagram images with this little trick, for example, since Instagram doesn't allow for regular pinch-to-zoom. And of course, any other app too.

Magnification gestures enable you to temporarily magnify what's on your screen.

How to use :

To enable or disable magnification gestures, follow these steps: Go to Settings > Accessibility >
Magnification gestures . Set the switch to the on or off position.
