I update android version of my Galaxy S3 to Android 4.3.
I have activated the developer mode by clicking Build Number and also checked in USB Debugging. I am using Windows 7 and Android Studio.
I have gone through various answer addressing same problem but none of them helped.
How can I install application directly to my device or debug using adb etc.
Go into device manager and uninstalled SAMSUNG Android USB Composite Device and ensured to check the box 'delete driver software'. Now the device will have a exclamiation mark etc ..i right click and installed the driver again (refresh copy) ...this finally made the adb acknowledge my phone as an emulator.
