Enable or Disable Magnification (Accessibility Zoom) auf OnePlus
Magnification is a system-level zoom tool built into the Accessibility settings on OnePlus phones. It lets you scale up parts of the screen without changing the font size app by app, which helps in apps that do not respect system text scaling.
The feature offers two separate triggers. Magnify with triple-tap zooms in whenever you tap the screen three times in quick succession, then you drag with two fingers to scroll around the enlarged area. Magnify with shortcut instead ties the zoom to a dedicated accessibility button, so nothing happens unless you press it on purpose.
To turn either mode on or off:
Open the Settings ➔ Tap on System ➔ Tap on Accessibility ➔ Tap on Magnification ➔ Choose Magnify with triple-tap or Magnify with shortcut ➔ Enable or disable Use service
If triple-tap zoom keeps triggering while you are gaming or scrolling fast, switch to the shortcut mode instead, since it only reacts to an explicit tap on the button. If you only need larger text rather than a magnified viewport, check the display font size settings first, since Magnification zooms the whole screen and can make navigation harder in cramped apps.
