It's not typically possible to lock the landscape orientation on an iPhone

I am utilizing the Screen Orientation API for JavaScript and encountering a specific issue. Whenever I rotate my iPhone to landscape mode, everything appears normal until I call 

screen.orientation.lock('landscape')
. At that point, the screen rotates but displays upside-down. Interestingly, this problem does not occur on Android devices. On Android, invoking 
screen.orientation.lock('landscape')
keeps the screen in landscape mode as intended. Any ideas on how to potentially resolve this discrepancy?

Answer №1

It turns out that the Screen Orientation API has a well-known issue. This problem is even documented on the library's GitHub page: https://github.com/apache/cordova-plugin-screen-orientation/issues/42, and the issue remains unresolved. In my situation, I decided to lock the orientation to the current landscape mode. For example, if the device is in 'landscape-secondary', I utilized 

screen.orientation.lock('landscape-primary')
. Why 'primary'? It seems that there is a mix-up in the settings, so locking to the same orientation as the current one may still cause it to rotate. Therefore, this appears to be an issue with the library itself.
