I have several apps for DSLR tethering on my nexus 7 (2013).
Previously, I was given a choise of which app I wanted to run when connecting my camera, but now one app automatically loads. Iam not given a choise anymore. how can I change this back?
 
Settings/apps/3 dot settings menu upper right corner then reset app preferences or goto that app and reset its defaults also through the setting/apps menu.
 
I am facing the same problem and i tried all the possible things but it won;t help, Can anybody tell me another solution.
