I have read many threads regarding the freezing issue, and my 0803 is annoying me because it randomly freezes with unstoppable beeping. Fellows have ruled out many possibilities like firmware, cards, settings, plug position(mount/camera), and I can rule out overheating because Canadian winter did not help.
Recently I took it home and plugged it to the USB cable of a Samsung charger that is plugged into a power bar with switch, so I randomly switch it on and off when I pass by to simulate the normal usage in car. For a few days of test, it worked like a charm, no issue happened.
So this is my guessing. I assume Samsung charger provides very stable voltage which is constantly 5v as stated, but a car adapter/charger that we buy from ebay may not do as well in terms of output voltage. The reason could be build quality, engineering accuracy, and what's more likely IMO, the normal input specs of 12v-24v is not wide enough. The power supply in a car can sometimes, especially right after cranking (the exact time when the freezing happens), drop suddenly below 12v for a very short and unnoticeable time which however could be enough for starting up the camera if the adapter cannot provide 5V power because of lower input.
Can anyone confirm or exclude this possibility if you have an adapter/charger that can handle inputs lower than 12v? like 8v-16v range? thanks.
