Having a much vaunted reputation of being one of the world’s leading budget smartphone makers,<br/> the Samsung Galaxy Ace Duos S6802 does quite well to maintain Samsung’s authority in the current market. The device comes in a bar shape and has a sleek look to it. The Ace Duos S6802 is a Smart Dual Active SIM, (GSM + GSM) device with both the inserted SIM cards being active at the same time. If you are on a call on sim 1 and you get a call on sim 2, the call would be diverted to sim 1 and the display would show it as call waiting.The same will be apply for both the Sims. So that we cannot miss out any calls on sim 1 and sim 2. This Samsung phone is run on the Android v2.3 (Gingerbread) OS with a snappy processor speed of 832 MHz. To assure the smooth running of apps, the device comes with an adequate 512 MB of RAM.
