Nexus Photo Viewer allows you to view the JPEG and RAW photos from a USB flash drive or SD card your Nexus device (5, 6, 7G1, 7G2, 9, 10) or other Android 4.0+ devices with USB Host support.
Requires the following hardware:
1) A USB OTG Cable (Cost approximately $1-10 USD on Amazon)
2) A USB Flash Drive or USB SD Card Reader and SD Card. See screenshots for hardware examples.
-The Nexus 4 does not support OTG/USB Host and can not be supported.
-DOES NOT REQUIRE ROOT!
-Hard Drives. It is strongly recommended that you use external power when connecting a hard drive to a tablet. Please see the troubleshooting guide on my web site for more information. Do not connect an unpowered hard drive to a phone!
This software is not produced by Google, which owns the Nexus trademark.
