Anyone trying to read CID, CSD etc should understand they can only be read when the cards are inserted IN THE BUILT IN CARD SLOT. This is true of all devices and OSes I've tried. It seems the controller in the USB/OTG reader doesn't transfer certain data to the system.
Used to work, latest update won't install. Get Error code: -505
Super easy to use app
Works great for me. Sony Xperia Z3 Tablet.
A very nice memories details app in play store.
