Yesterday a strange thing happened: I was trying to connect my F1G2 to the PC using a USB-microUSB adapter.
Nothing happened, but suddenly the small green light near the USB charging plug started flashing.
The orange led became green, too.
I tried to connect it to the smartphone and it was recognized by the Flir App, I checked in the setting menu and the firmware resulted up to date.
After few seconds, the led turned into orange again and it was not possible to use the camera, just pushing the power button, the green light turns on again, but it lasts very few seconds.
