It might be defective, and it might be putting out too much voltage, and the device might be shutting down to protect itself.
The 4G/WiFi behavior is wierd.
The phone has been plugged into her OEM cable and to my OEM cable. We have the same phone purchased at the same time. My phone doesn't have the same issues and we interchange cables frequently.
