Textures rendered black

I am experiencing a rendering issue with a game (OpenGLES2): all Truecolor textures are rendered as full black in all Android devices with GPUs Adreno or Tegra. Compressed textures are displayed ok. At first I thought it had to do with the size of atlas, but nope, all atlases are 1024x1024, tops. It only happens with those GPUs on Android (it works ok in all iOS devices).

So my question is: are Truecolor textures unsupported on Android devices with Adreno or Tegra gpus?

My game uses uncompressed truecolor textures wit no problem, some of them are 1024x1024. Works on tegra 3 too.

I see. Did you enable 32-bit buffering? And or multithread rendering?

Hi, the problem was serialization of assets (mixed). Once I set it to binary mode, all textures were rendered ok on said GPUs.
