I got the Vanja sd to sd copier device. It worked ok at first although the fit was a little loose (c type to c type charger slot of the Moto G Stylus). I didn't use it for maybe a couple days, and yesterday when I plugged it into the phone, the red light did not light. It looked all right but still didn't work with multiple repluggings. I figure my best bet for now would be to give up on the Vanja and simply swap sd cards. Probably I can finish copying over from the old to the new later, maybe with a computer. Can a Vanja be fixed, and if it can, how?
