My wife's Samsung phone is so incredibly foreign to the vanilla Android experience. I have had some recent issues with Google Maps draining my battery, but that was corrected by simply reverting the update. All in all, a great phone. If I destroy it, I can just get a new one for $250. Flops consisted of the wireless battery charge, frictionless glass back that slides, and (original) nubless back that left the speaker against the surface.
