Hello, unlocking my phone

[AC Question]

I have sa amsung note edge. When ever I try to print photos from my phone at walmart photo kiosk etc, I am unable because 'the phone is locked'. I use my phone for everything, thetefore i am not sure which part is locked or how to unlock it. They don't know how to help, can you?

How are you connecting to the kiosk? Is it USB? If so, pull down the notification shade once connected and tap the USB connection item to change the connection type (I believe the default is charge only rather than data transfer or MTP).
