Hello, after import my proyect on Unity 5.5 I have a problem with a device, Samsung Galaxy S Duos GT-S7562, Android 4.0.4.
When the app is set to Autorotation and I rotate the device, the image gets corrupted (dispaced, tiled and with strange artifacts on some areas). It was working correctly on Unity 5.4.3.
Not sure if this would help you, but I noticed this problem before on the first screen of my game. My issue was to do with my UI, scaling. If the panel wasn’t set to stretch mode then it would get corrupted when rotated into landscape.
