I brought Galaxy ace s GT 5830 Last year for INR 15500. At first the performance was good but its terrible. Performance is terrible, If you try to run multiple application, the software forcefully close the application and hang the phone. You have restart the device. Secondly sometimes it silently shutdown, you could realize it only when you check that why no one called you for long time......believe me its terrible phone....Samsung try to imitate the iphone but it failed to do so....I hate Samsung for bcz they are more like China (Imitation) rather than come up with own innovative products.
Never buy Samsung products....
