Mobile QA and office automation share a problem: a gesture workflow that works on one phone often behaves differently on another. Screen size, display scaling, keyboard, and manufacturer battery settings all change where a tap lands.
A minimal regression checklist is: model and Android version, display scale and resolution, keyboard open or closed, screen timeout setting, and battery optimization state for the automation app. Run the same workflow with the screen unlocked, then with the screen locked, and write down the failure point.
Phone Operator is a no-root Android tap and swipe automation app I built for repetitive personal workflows and mobile testing. It performs only user-configured gestures via the Accessibility Service. The free version includes unlimited single-point tapping; Pro is a one-time purchase for advanced scripts, and rewarded ads can temporarily unlock Pro.
The goal is not a perfect matrix of every device. It is a repeatable record so the next device test takes minutes instead of an afternoon.
