Hi,
I am making a game with Unity 4.2 free, and have a rendering problem with Huawei Y300 and G300 (only after official update to Android 4.0, works correct with 2.3.3). Everything works correct with other tested devices.
The problem is rendering trails, it seems buffer is not cleared before rendering frame.
I shot a video of how it looks:
