The GPS does not work well, and when it is switched on it very quickly empty the battery. Nothing to say photo mode, but the video does not propose that the maximum 1080 / 30i mode. No external charger is for charging cord, which is good and bad. Nevertheless it prohibits a second battery. The dimensions are good, it still fits in a shorts pocket. Last, I did change by Amazon from time to time because the power button was not operating.
