on a Galaxy tab 2 7 ver. 4.1.1 I can transfer pictures with a OTG usb adaptor using a Kodak Easy Share but not with a Nikon CoolPix s4300. With the easy share, the gallary opens automatically and after clicking on the pictures, they all open. With the Nikon, the pictures are visible for a second or so, then disappear. In "my files"app, the Nikon isn't shown. Is this a camera specific problem with the Nikon? If I take the sd card out of the Nikon and put it in a card reader connected to the OTG cable, all is fine. Any thoughts? TIA, mark s
