[Android] InputSystem throws errors while clicking in Samsung Dex when using EventSystem



How to reproduce:
1. Open a new project

2. Enable new Input System

3. Build and Run on Android (make sure to use Dev or Debug build)

4. Deploy to a device running Samsung Dex

5. Click anywhere with a mouse

Expected result: Errors are not thrown
Actual result: Buttons can’t be clicked with a cursor and the errors are thrown in the console:

`Touch Unhandled event action: 11`

`Touch Unhandled event action: 12`

To see the errors a Development or Debug build should be used

Reproducible with: 1.4.3 (2022.1.23f1, 2022.2.0b15), 1.4.3, 1.4.4 (2021.3.13f1, 2023.1.0a18)
Couldn’t test with: 2020.3.41f1 (“Assets\Scenes\SampleSceneControl.cs(12,59): error CS8124: Tuple must contain at least two elements.” error after project downgrade)

Reproducible with these devices:
Samsung Galaxy S22 (SM-S901B), Android 12, CPU: Exynos 2200, GPU: Ltd.
Samsung Galaxy S10+ (SM-G975F), Android 10, CPU: NOT FOUND, GPU: Mali-G76
Samsung Galaxy Z Fold3 5G (SM-F926B), Android 11, CPU: Snapdragon 888, GPU: Adreno (TM) 660

Can’t test with: iOS (Samsung DeX is not supported)

- The description has changed from the original bug, as the original bug will need to be fixed in the InputSystem package, and this bug will only track the fix for the errors

  1. Resolution Note (fix version 2023.2.0a17):

    Fixed errors that are thrown on Samsung Dex when using mouse. The fix for clicks will come in Input System package

    Reported this issue on Pixel 7 devices and was told this a duplicate:

    I am now on Unity 2022.3.2f1 and the bug still occurs! UI buttons on a Pixel 7 Pro do not respond to touch input.

    Forgot to mention: The buttons can't be clicked using the VR headset's controllers, but can be with a paired bluetooth keyboard.
