Android 6 Marshmallow Update But Can't See Media on SD Card to Transfer to PC
Just updated my brand new Motorola Moto G 3rd Generation to Android 6 Marshmallow and selected "Internal Storage" for my brand new SD Card. This migrated all my photos and video from my old Moto G to the SD card. When trying to view the photos and video on my PC it couldn't "see" any photos or video on the SD Card.
The answer I found online may help others. When you plug in your charging/data transfer cable, check the pull down notification bar on your mobile's home screen. It says by default "USB for charging" but adds "Touch for more options"
These options allow you to select:
TRANSFER FILES (MTP)
TRANSFER PHOTOS (PTP)
I selected "Transfer Photos" and they all came up on my PC - problem solved!.
Hope this helps others who experience the same problem with the Marshmallow update.
