Along with Views, Google shared a best practices video for taking good photospheres. It shared pointers like holding the phone close to your body (guy in the video looks really awkward, though), tilting the phone rather than panning down, and using it in portrait mode (which is a party foul in every other instance).
If photospheres are also one of your biggest annoyances with Android Jelly Bean, I’m right there with you. The photos don’t stitch together properly, and they often seem like you took them too fast or slow. It’s great when you get it right, but when you don’t, it’s an embarrassing headache.
