If you need to flash, upgrade, root or unlock your Samsung Smartphone via any tool you need to enable USB debugging mode in order to connect and communicate with your Android device. This mode is not only useful for connectivity, but helps in sending command code to your Android smartphone. By default the USB debugging mode is disabled for any brand new device to avoid unintentional modifications on your device. But you need to enable debugging option manually for your Android development process. For different Android versions there will be different configurations to turn the USB debugging mode.
Features of Developer Options
The “Developer Options” feature is indispensable to Android developers, hackers and enthusiasts as a means to quickly access and control their device from the PC. Even if you are an average user and wish to root, install a ROM or mod on your Android device, you must turn on USB Debugging mode on your phone or tablet. And you’ll not be able to do it unless you enable Developer Options on your device first.
Among the most useful features that are found under Developer Options are as follows:
- Enable debugging over USB.
- Quickly capture bug reports onto the device.
- Show CPU usage on screen.
- Draw debugging information on screen such as layout bounds, updates on GPU views and hardware layers, and other information.
- Many other options to simulate app stresses or enable debugging options.
