Some call it diversity, some call it fragmentation. However you slice it, there's a lot of Android devices out there. OpenSignalMaps has tracked a staggering 3,997 unique phones, tablets and other Google-powered gadgets, and has put them into a chart weighted by popularity. Not surprisingly, it's powerhouses like Samsung's Galaxy S II and HTC's Desire line that dictate the platform, while that Concorde Tab you bought in Hungary sadly doesn't have much traction. The normally signal mapping-oriented crew is careful to warn that the actual variety might be less: there's 1,363 one-timers in the group, and some of those may be custom ROMs and the endless carrier-specific variants that OEMs are sometimes eager to make. There's even more to look at through the source, including Android 2.3's continuing dominance and the mind-boggling number of Android screen resolutions, so click ahead for an even fuller picture.
