I decided to test blender´s last year port to android. It is not very usable.
But render is working very well.
I used mushrooms by ahmad maad, and my tablet (Dual core ARM Cortex A9, 1.6 GHz, 1GB RAM - GPU MALI 400).
It took 3:30 minutes to render, the tablet didn’t feel hot at all when i touched the cpu part, and here is the result.
Hoping for a new and better port. It looks promising :).
