I have noticed that. In the tracking app there is a function to connect the positions with a line on a path. That does not work. So you only have a point cloud, which can hardly make a statement about the way. Only where you have been times.
Tracking in GPS mode is quite accurate. On the other hand is not the GPS signal is available, then the device switches to tracking via GSM network. However, this function is so imprecise that it would be better to disable this feature completely. The Tracker was with me in the apartment and was not moved at all. The displayed in the tracking app point are about 2 km away from my location and distributed in addition within a radius of about 2km. So if I wanted to know where the tracker is, then I would have with this tracker only the information that it is in an adjacent municipality. But I do not need a tracker.
Also I have noticed that the acquisition rate is set, but the attitude seems to have no effect on the actual location frequency.
Overall, I am not at all satisfied with this device, because it its main function (namely reliable to report its position) does not reliably fulfilled. One can see that the idea was really well-intentioned. The manufacturer has the product but apparently has not finished developing.
