OpenGL ES 2.0 broken on Nexus 4 in landscape mode

I've found that OpenGL ES 2.0 doesn't work on my Nexus 4. Specifically, GUITextures are positioned as if it's portrait mode, and some imported models with multiple meshes get "split" and move separately from each other. Switching the Graphics Level in Player Settings to OpenGL ES 1.x fixes these problems, but I want to develop for OpenGL ES 2.0. Both settings work on my Kindle Fire HD. Both even work on my Nexus One(!?). Just not Nexus 4. Will try to find some other Android devices to test on.
