It’s no secret that Google’s Play Store is chock full of crappy apps — just drop the word “guide” into the search bar and see for yourself — and Google itself knows it, too. As an example, take the latest change the company announced on its Android Developers Blog: apps with performance issues will now be downgraded in search results. Sure, it’s far from tackling the problem head-on, but it’s a start, anyway.
And it seems the change has been in effect for some time now — enough for Google to build a strong enough data set, anyway. And according to it, the results have been positive: higher quality apps (as per Google’s definition) have seen an increase in usage and decrease in uninstalls.
