Android: Game runs in "squished" aspect ratio

Not sure the exact trigger condition but sometimes when opening the Application on a mobile device, it opens in a very squished aspect ratio. I suspect it has something to do with the orientation/auto-rotation. It’s almost as if it thinks the mobile device is still in portrait mode and double stretching instead of always just launching the game in landscape mode.

My game is set to “Landscape” orientation under the Android platform build settings. Not sure if someone else is having similar issue and has a solution.

Tested on several different android devices and having same problem across different devices. (Samsung & Google Pixel)

From older engines, this was a result of the windowd feature - particularly on tablets or samsungs which supported it.
To get the game to launch right you needed to remove/change and hard set the startup parameters of the video settings.
“Windowed borderless” sort of thing leftover from the PC side was what was causing the issue
