Formerly known as Nexus Photo Viewer, USB Media Viewer allows you to view the JPEG and RAW photos from a USB flash drive or SD card your Nexus, Pixel 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.

Technical Notes:

-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!
