New member here who found this forum as a result of a Google search on opinions of Waze. I have been trying hard to like it (using it on my Rezound), but it is not dependable. There are several locations in our ticket hungry county where speed cameras have been in place for months and are not reported on Waze, whereas a car on the shoulder pops up almost immediately. I have stopped alongside a speed camera, reported it to Waze, and weeks later it is still not shown. I have tried unsuccessfully to fix a mapping error in our neighborhood (remove a section of roadway that does not exist). Twice, the app froze up on a two hour trip. It's almost a case of information overload, with many errors.
My main concern is the proliferation of speed cameras and red light cameras in our county. I've been comparing Waze to CamSam, and I'm much more satisfied with the operation and reliability of CamSam. As the only app running, it has a plain unobtrusive display with a green arrow until one approaches an area with a speed camera or a red light camera. CamSam then provides both an audible warning and a visual warning that one is approaching the camera. If used in conjunction with Google Navigation, one only hears the audible warning. With Waze, one might be warned of police activity (radar, on shoulder,etc.). CamSam does not have this feature, nor does it provide any traffic information.
