I bought the S01 as a third camera for your pocket as it is so beautifully small and I am not one of those people who constantly carry around their phone. Unfortunately I have been unlucky and caught two mounting specimens that have repeatedly annoyed with error messages. After Amazon there was very accommodating now a new experiment with the S02. The external values are still very attractive. Small and cute and sylish. The touch screen has grown a whole number and responds better than its predecessor. The flash mode (Automatic / lightening / off) works this time directly on the touch screen and without detours via's Menu. There's also a couple of small exposure programs (Freehand recording at night / Backlight / automatic). So far so good. Another new feature is the HDMI output than significant increase compared to the previous model. Now times have a first trial run completed and am very happy with the first gross 100 images. Better quality than my iPhone, very fast response time, short processing time ..... and above all: no error message. As a snapshot camera for the pocket or bag (or wherever you like Insert) optimally. For mobile muffle like me a very nice third device.
