Sorry but we've had a lot of back and forth and it appears that you are fishing for something other than what I offered.
Try again, and asking me the same question more than twice has me wonder if I didn't understand your question. If you want a definitive answer if Google tests for performance, you'll have to ask them but it's pretty clear in my experience it's not a factor. That is, I've seen apps that can't perform on some slow tablets yet you can get them from the Play store. That's my proof.
However why would this be a concern here? Maybe if you elaborated I could answer that.
I'll write that Android is a far more open system and less of a Nanny than other systems. I'm wondering if some of today's consumers need a Nanny state/company.
I've heard that to post an app on the Android market, you don't need to have it confirmed (tested) by Android. It'll directly on to the market and anyone can download it.
Is this true?
