Which mobile devices do not support stencil buffers?

I’m mostly interested in iOS, but knowing something about Android would be nice too.

I know I have to enable “24-bit Display Buffer” in order to get working stencil on iOS. Does anyone know which devices do not support that?

As far as i know, Tegra2 and Tegra3. I got really angry because of it :P.

Couldn’t use Unity’s realtime shadows. Tegra4 added stencil to the chip i think.
