Why does Nexus7 crashes with Open GL 2.0?
Hi, I've created a little app with Unity3D and I'm trying to install it on several devices. The app runs fine on: iPhone4, iPhone4S, iPhone5, iPad2, iPad3 And also runs fine on: HTC Desire S, Samsung Galaxy S3
But on the Nexus7 the app crashes when I choose "Open GL ES 2.0". When I choose "Open GL ES 1.x" everything works fine.
So: Why does the little HTC Desire S accepted Open GL ES 2.0 but falls back to 1.x (what is, what I expected) and the new Nexus7 crashes on 2.0 but runs fine at 1.x?
This is, what the log says:

I'm not familiar with that error, but knowing what I know about the Nexus 7, having a Tegra 3 it is not a matter of support for the programmatic pipeline as it definitely has that.
Most likely there is something in one of the shaders you are using which is generating this error on that device. Without additional information I can't say as to what shader may be causing this.
Hope that helps.

Hi equalsequals,
surprisingly it was a shader problem. Thanks for your advice. After switching to mobile shaders only, everything works fine.
