I have Pentax SLR camera with regular SD cards and micro USB slot. I am wondering to buy a tablet for previewing and backuping photos. How can I transfer photos from my camera onto Samsung Nexus 10 without using PC computer?
The Nexus 10 android 4.2 doesn't have this basic feature by default. However, a paid app from Google Play store called "Nexus Media Importer" can help you directly copy and stream music/video/photos and documents from a USB flash drive or SD card connected to your device without any hassle. It is very useful while I am traveling.
Stickmount app also allows users to read memory card and flash drive, but only works on rooted device. It bring up an option for hooking up with external more storage.
