DeviceIdiom detects notebook as tablet

[lenardg]

Description

There was an issue on this already, #11126 , that has already been fixed in MAUI 7 and 8.

However, we are now seeing this behavior again with the latest MAUI version. We have a ThinkPad P1 Gen 3 notebook that has a touchscreen. This device is detected as DeviceIdiom.Tablet. Note that it is not possible to fold the screen into tablet mode, this is a regular notebook.

We use Windows 10 and tablet mode is OFF. In fact, the notebook is connected to a dock, the internal (touch) display is off and an external keyboard and mouse is connected.

I think DeviceIdiom should not be Tablet at this point.

Steps to Reproduce

Just read DeviceInfo.Current.Idiom on this device, which will say Tablet.

Version with bug

8.0.82 SR8.2

Is this a regression from previous behavior?

Not sure, did not test other versions

Last version that worked well

Unknown/Other

Affected platforms

Windows

Affected platform versions

Windows target 10.0.19041

Did you find any workaround?

For our purposes we can treat WinUI always as a desktop:

IsDesktop =
		DeviceInfo.Current.Platform == DevicePlatform.WinUI ||
		DeviceInfo.Current.Idiom == DeviceIdiom.Desktop;

But I think this is wrong behavior.
