Current Behavior

When locking the screen orientation to 'landscape' it locks it to landscape left. Meaning that if I'm holding my phone in landscape right mode, the view rotates 180 degrees and locks there. (Same goes for android with landscape and landscape reverse).

You can see this is how its configured in the plugin code:
iOS:

capacitor-plugins/screen-orientation/ios/Sources/ScreenOrientationPlugin/ScreenOrientation.swift

Line 87 in be3dd68

case "landscape", "landscape-primary":

Android:

capacitor-plugins/screen-orientation/android/src/main/java/com/capacitorjs/plugins/screenorientation/ScreenOrientation.java

Line 62 in be3dd68

case "landscape":

Expected Behavior

If the phone is physically held in either landscape left or right (normal or reverse for android), when locking the orientation to 'landscape' it should lock the current orientation without rotating anything.

Other Technical Details

Additional Context

Updating the issue as a feature request as you can achieve explicit "landscape right" by using the landscape-secondary option.

@IT-MikeS This issue and #2022 are similar but not the same.

iOS is broken on lock, not just when locking to 'landscape' because the Landscape Values returned by different native level functions are from different objects and are NOT equivalent.

@IT-MikeS To clarify, the issue is not that the app cant be locked to "landscape right", its that the "landscape" option in the plugin is defined as just "landscape left" instead of both "landscape left" and "landscape right".

Understood, Im going to leave it as a feature request as it changes current behaviour of the plugin, however I agree that landscape option should respect the current rotation the device is in when being locked.

This issue would be resolved by making a separate case statement for "landscape" here:

capacitor-plugins/screen-orientation/ios/Sources/ScreenOrientationPlugin/ScreenOrientation.swift

Line 87 in be3dd68

case "landscape", "landscape-primary":

And returning UIInterfaceOrientationMask.landscape
