Me and wife got our v10's about 3 weeks ago. My wife's lately been noticing the screen turning on by itself when locked and sitting on the table. It does it a lot and imagine it's wasting battery. We're on Verizon if that makes any difference.
Mine does so when some notifications arrive. The phone remains locked, however. No biggie. The screen goes off in a few seconds, and it doesn't affect the Doze feature.
