Of course not! Why would you think that?

All this says is that devices running Android fail on average more often than iPhones – for whatever reason (regression to the mean, one designer and manufacturer vs many, lower priced devices, and so on). That’s a perfectly valid comparison.

The comparison is invalid because iPhone/Blackberry devices are premium high cost devices with high quality control. A direct comparison will only work against other premium high cost devices with high quality control.

By comparing every Android phone on the market (from cheap to premium) to only premium devices you are always going to get a skewed result.

I don’t understand. Why does that make the comparison invalid? That makes no sense at all.

You are naming one factor that might explain the difference – but that is exactly the point of such comparisons! To figure out what the difference is!
