2 OS versions ago, android changed the system wide zoom gesture to a single finger one. double tap -> hold -> move finger up or down This doesn't work in Android, which is still stuck on the old iOS style pinch zoom gesture. Is there an option to fix this? If not it should really be filed as a bug, since every other app I use on Android works the new way. I'm used to the one finger gesture and much prefer it, and I suspect other users feel the same.
