Touch Screen Test 5.2.0

This app is a straightforward tool for device testing. It allows users to easily check the status of the touch panel, including multi-touch functionality. Additionally, it can be used for drawing and graffiti purposes.

However, it's important to note that this app does not support communication features.

How to Use:

• Touch the screen to draw a circle at the touched point.
• To clear a touched point, press the volume up button.
• Rotating the screen will also clear the touched points.
• To exit the app, press the volume up button twice after activating it using the volume button.

Comment:

The trajectory points represent the state of the elements passed from Android. The app captures and displays these elements as they are, without any processing. This allows users to easily observe device characteristics, such as stability when it comes to multi-touch interactions. For devices with intermittent touch response, you may notice instability when drawing periodically disturbed points.

We have also added a version that allows drawing in a linear shape, adding a bit of experimental functionality to the app.

Permissions:

None required.
