Most of these low-end phones end up running an older version of Android (2.2), two major phone releases behind now that 4.0 has been released (not including 3.0, as that was tablets only). From what I have seen, one of the problems with running newer versions is ram and memory sizes; low-end phones simply don't have enough to run the newer versions of Android. I've got a Nexus S, one of the more powerful phones before the dual-core generation started. If you compare its specifications to the galaxy ace, one of the current generation low-end phones, they are actually quite similar. When you consider the Nexus S can even run 4.0 (officially too), something might be changing. Although, the galaxy ace probably lacks in the gpu area.
