About Mouse Test
Check left, right, middle and side buttons, scroll wheel and movement on a USB or Bluetooth mouse.
A mouse test confirms that every button, the scroll wheel and the sensor work as they should. It is the quickest way to find a failing left click, a scroll wheel that jumps the wrong way, or side buttons that never register. On Android you can test any USB mouse on an OTG cable or any Bluetooth mouse, which is handy when you have no PC around.
How To Run A Mouse Test
Connect the mouse, open the tester and press left, right and middle buttons one at a time. Then press the back and forward side buttons, scroll up and down slowly, and move the mouse in circles. Every action should appear once in the log, in the right direction.
Common Mouse Faults
- Double clicking: one press registers twice, a worn switch problem.
- Scroll jumping: the wheel moves the wrong way, often a dirty encoder.
- Dead side buttons: missing drivers or a broken switch.
- Jittery movement: a dirty sensor or a shiny surface.
Which App The Install Button Opens
The button opens a related app, Simple Keyboard & Mouse Tester on Google Play, which logs mouse movement, button clicks including extra side buttons, and scroll wheel events. If clicks seem to repeat, run our Double Click Test too.
