I'm not talking about the lock screen, I'm talking about screen lock, and I'm talking about the mobile, not the desktop.
How would you even take a photo in landscape using the desktop?
I wasn't talking about desktop with your photo issue.
And I don't know what you mean by screen lock if it's not the lock screen. However, as I said: the photos are properly oriented within the app so whatever your issue is, it can't be that urgent...
At this point I'd say you desperately look for something to complain about. Why don't you just not use it and check your PC? There is obviously something wrong with it.
