Nexus 7 depth buffer precision issue

Did anyone else notice that Nexus 7 has lower depth precision compared to other devices?
It should support a 24 bit depth buffer, but it seems to be using 16 bit instead.
Just wondering if that’s a known issue and if its the devices fault or a bug in Unity.

All Tegra 3 devices have 16-bit depth buffer. I assume you mean Nexus 7 2012
