Samsung Epic 4G was launched a very long time ago. At that time, it came with Eclair Android OS (2.1) and it was up-gradable to Froyo (2.2). It has a 1 GHz Cortex-A8 processor with a PowerVR SGX540 GPU. It was also loaded with a 512 MB RAM and a 512 MB ROM. And the 5 MP camera just added to the great specifications of this device.
