Flashing light on DataTraveler G3 flash drive plugged to Android Tablet

[zhong]

When I use usb cable to plugin 8 gb DataTravaler G3
to Curtis 7029 Android tablet.


It keeps on flashing even when I don't click on a file
inside flash drive and just plug it in to tablet.

But this doesn't happen on older Kingston DataTraveler flash drive which are like 4 gbs, 2 gbs, and 1 gb.

Is this normal or something in G3 flash drive causing this to happen ?

Thanks.
