How it works : Why doesn't my Paper Shoot camera work?

Basically, there are two main issues that cause this problem :

1) SD Card
2) Battery

You will notice it when you hear an abnormal sound and see the following light indicator at the back of the camera :

[SD Card Issue]

It indicates that there is a problem with the SD Card. Please reformat the SD card with your computer. Kindly do not use SD card that exceeds 64GB.

[Battery Issue]
Right light or Both LED lights
It indicates that there is no power. Please charge the batteries for at least 30 minutes before use.
