A:Answer I can't say for use, but since Android KitKat, you can use USB OTG, so you can add a flash drive to the phone, though it would be something extra to carry around. Best Buy had a great deal on the Sandisk 32gb Duo, which has USB 3.0 and micro USB built-in. I like the design of it as it easily fits on my keychain. It's really small and super fast due to USB 3.
