I have been using Samsung Galaxy Y Duos for the past 2.5 Years. The battery is long lasting. Once I charge the battery 100 percent it is there for next 2 days without charging.
More ever the features in this phone is good and the camera quality is good being 3.15 MP with dual sim and extendable memory slot upto 32 GB.
It is provided with emulators which helps the android developers to use this future to test the android application.A good device that fits in the budget for anyone. It also provides the user with different colors to choose with.
