Lately we are seeing a strange bug that occurs on iOS.
If the app is open and in the foreground, then you lock the screen, then open the lock-screen - after 1 second it flips from landscape to portrait, then after 1 second it returns to landscape.
This switch is not followed by a “resize” event, and the ui is not actually re-building.
It’s as if a screenshot of the app was taken, rotated, then returned to correct orientation.
This happens with the latest daily build (2997) and even in builds before that (2987).
I downloaded it on my iPhone 6 (iOS 10.1.1) and I did not observe it. I start the app. I turn it off using the button on the side of the phone. I press the home button and unlock the phone. It returns to the game exactly like I left it. I tried switching orientations too while the phone was sleeping.
can you test without clicking on the home button? the device should be locked while the app is in the foreground. Then, when you unlock the screen the first thing you see is the app (and the rotation)
I tested on my iPhone 6s Plus (iOS 10.1.1), and I can see the issue *sometimes*, and only when I hold the phone in portrait orientation. If I hold the phone in landscape I do not see it happening.
Most of the time (while holding the phone in portrait) I can see a very brief “black flash” when opening the app from background without noticing any orientation change. I’m guessing that the “black flash” is the same issue, it’s just that the orientation change happens so quickly that it’s not rendered to the screen. Sometimes I do see what @stanga mentioned in his first post: the screen contents is briefly shown rotated and is later shown in landscape. But again, this *only* happens if I open the app while holding the phone in portrait mode. If I hold the phone in landscape mode, I see no “black flash” or orientation issue.
