Samsung tablet Tab A, not able to download photos

On my second or is it my third Tab A tablet in 18 months, meets a untimely ending? Not able to just plug my camera in to the latest purchase, another tablet, turn the Canon camera on, letting it automatically download all the photos in it to the tablet, then saving the new ones. That slick and easy, nothing else to do but unplug the camera cord from the tablet. Now, the screen on the new tablet changes and I cant figure out what to do nor how to tell the tablet what to do from there. No help online, refers to other tablet models or nothing pertaining to what I see as options on mine. Dont want to have to jump thru 20 hoops to get photos onto the tablet. Called Samsung earlier for a online chat, but the tablet ran out of scroll down space to reply with the actual issue so had to leave the chat. Maybe I should go back to a PC?
