2. If so, please turn off your dash cam and plug it in the original car charger with 5V
for about one hour, then turn it on to see if it works normally.

3. Otherwise, please restore it to factory settings if the two methods do not help.

This issue may result from the low temperature which causes static. Please try touching the screen after rubbing your hands together.

There may be something wrong with the firmware of your dash cam. Please kindly contact the customer service for the warranty claim. Don’t forget to send some photos as a proof.
