Hi I'm new and have no idea where to start. I did do some searching but couldn't find an answer. I have an RCA 7" tablet and am wondering if I can use a card reader on it. I 'think' an OTG card reader would work, but it says OTG has to be enabled on my tablet.My Micro usb port says - connect to PC or storage device or charge. I did search for how to tell if my tablet has OTG enabled, all I got was download some app but reviews say it dumps a lot of ads on your device and isn't reliable in the first place. Can someone point me in the right direction, please.?
