I have a nexus4 and in developer options I switched on USB debugging. After I connect it to my PC and press run from eclipse to test the app on my phone the app does not run! The window shows the option only of them emulator but not of Nexus4 I have nexus 4 drivers installed too. What can be the problem?
Did you go a pressed "Build number" 7 times in the About Phone settings?
