If there's any chance that something nearby the camera has the physical ability to touch a button or smack the body, it could cause for a poor experience.
I recommend doing a hard reset, pull the battery, press the power button, & install the battery.
then, download the APP, set it up how you want it, paying close attention how it functions when you power it on.
The power button has two abilities. Quick press brings it on to function how you set it up to record. A long press should power it on to the system selection status.
the camera does not like getting wet, so using the clear protective case is highly advisable if it's exposed to wet tire kick up.
I'm not a rep, just a user.
