Samsung Epic 4G Touch Repairability Score: 7 out of 10 (10 is easiest to repair).

Battery and microSD card can be accessed by simply removing the back cover.

There's a total of 9 Phillips #00 screws to remove to gain access to the majority of the device.

Most of the disassembly was straightforward and easy, and accomplished with standard tools.

Some components share the same ribbon cable (front-facing camera and ambient light sensor, for example), thereby increasing repair costs.

Speaker is soldered to the motherboard, making replacement more difficult.

Glass panel and Super AMOLED Plus display are fused, making cracked screens a costly repair (and requires the use of a heat gun).
