Surprised no-one's posted this yet:
Intel claims Android is not ready for multi-core processors

Intel's internal testing had shown multi-core implementations running slower than single core, however he did not finger any particular chip. "If you take a look a lot of handsets on the market, when you turn on the second core or having the second core there [on die], the [current] leakage is high enough and their power threshold is low enough because of the size of the case that it isn't entirely clear you get much of a benefit to turning the second core on. We ran our own numbers and [in] some of the use cases we've seen, having a second core is actually a detriment, because of the way some of the people have not implemented their thread scheduling."

... Finally Bell claimed that Android doesn't make use of multi-core processors, something he thought other chip firms should work on sorting out alongside Intel. "The way it's implemented right now, Android does not make as effective use of multiple cores as it could, and I think - frankly - some of this work could be done by the vendors who create the SoCs, but they just haven't bothered to do it."

Then there's this comment in PC World:
even the latest version of Android, 4.0 (Ice Cream Sandwich) suffers from problems with threading scheduling that limits the benefits dual core ARM processors bring to Android phones

Battery, anyone?
