This guide tells you how to remove the back or rear panel of the Samsung Epic 4G, which is an important first step in working with the internal parts of the phone.
Turn off the phone using the "Power Button". The Power button is located on the left side of the phone and has a circle on it.
To remove the back panel of the phone, slide your fingernail along the edge of the device and pull at the panel as shown in the figure. While pulling at it along the edge you will hear a snap. That snap tells you that the panel is coming off the phone.
After hearing the snap you should be able to remove the plastic backing by pulling at it gently.
