I took my Droid 4 out on a very cold morning the other day, and its touch screen behaved very erratically. While I was not laying a finger on the screen, the screen was panning up and down, zooming in and out, and clicking things on the screen. It was definitely due to the cold air, because I have not seen it behave like the before or after. It did behave like that again later that day out in the cold air again. Is this a known problem with Droid 4? Any fix for this?
