My S4 is Not Powering Down (Upgrade Package)
Now that your Ergatta Upgrade Package is set up, the tablet is in effect acting as the power source for your S4 monitor. If you're having trouble powering off your S4, please be sure to hold the power button down on your tablet for 3 full seconds. You should see a message on your tablet's screen that says "Powering Down." Once your tablet is fully powered down, your S4 monitor will also power down.
