I like to start my app directly on Samsung S7 with AndroidStudio.
I have already enabled debugging mode in the developer option by tapping 7 times on build number, but still I don't see the device when starting the app and getting the "Select Deployment Target" Dialog.
What else do I have to do ?
In developer options at bottom of setings menu, ensure USB debugging is ticked. Then start again, restart windows and S7 to make sure and try again. With one of my devices, tapping seven times enabled developer mode, but the debugging options was not selected by default and had to be manually selected from developer options after they were enabled.
