The developer options are disabled by default in Android. So this is also the case with the new Samsung Galaxy S6. In order to unlock the developer options at the Samsung Galaxy S6 within the Android system, you must use the following workaround:
Open from your Homescreen of the Samsung Galaxy S6 the menu and then the Android settings. Scroll down here to the "About Phone" and tap on the entry.
You now see various information on the screen. An entry is called: "Build Number".
In order to unlock the developer options you have to type in rapid succession on the entry "build number". After the seventh time tapping the entry a message box will appear on the display with "developer options enabled".
Congratulations! You have now enabledin your Android operating system the developer options. These can now be opened in the settings.
