It appears whenever you restart or unplug your device.
I was getting it constantly too but it turns out this is warning you that your back cover is not sealed all the way. You need to put the back cover properly by starting by pressing from the center out (near the camera is the first snap that needs to be pressed in) and continue to press down outwards like the arrows show on the plastic cover that was on the back when you received the phone.
