Also with me the Cam go to the one time or another, allegedly because the Class 10 SD card is too slow.
In addition, the app on the Samsung Galaxy S3 was not usable. Despite several attempts and a lot of patience the App ultimately led only to the fact that the whole mobile adopted. Was for me now but not so bad, for the control of the cam there is the well-functioning remote control.
In addition to the above problems then the big disappointment on vacation: The test in the swimming pool (1.3m deep) meant that the cam completely full with water and ran after 2 minutes was dead. This was because of the (theoretically waterproof final) cap is screwed back on the Cam solely on the battery compartment. This battery compartment is closed by a much too small and much too weak plastic clip, which
a) can keep the battery in the compartment hardly so that the battery cover pops open fully when you exert slight pressure to the housing bottom.
b) the back pressure by the waterproof final cover does not stand up, so as to form on the side with the small plastic clip a small slit.
This is in my opinion a gross design error that causes that to be very great Actioncam with good shots and very long battery life, only 2 stars earned as product features are not respected and result in that these floats like a stone.
