Only on Android, not iOS, I think. You've always been able to do this, even longer than you could pinch-zoom. Unfortunately, it seems to be going away—Chrome no longer zooms on double-tap-drag, nor do any of the Samsung apps (Samsung Internet, Photos, etc.).

I have a workaround for you: assistive touch under accessibility allows you to bring up an on-screen two-handle bar which lets you adjust zoom with one hand.

My full workflow for using this is triple click power key to bring up accessibility shortcuts, press assistive touch and then tap on the circle icon to bring up the bar. You can drag it around by dragging the middle and if you drag either bar end it does the “pinch”.

I put smart invert for pseudo dark mode and zoom in the other two accessibility shortcuts to round out the accessibility shortcut menu.

It does work on iOS but seems app-dependent. Works in Apple Maps, doesn't work in Photos.
