A good product by Samsung. I just used it for a month and it is working perferctly. The product looks great like a very expensive phone. Rear Camera is the best and front is excellent. The phone has no lag at all during heavy gaming but gets heat up a bit. The sound is loud and crisp while listening to music and while calling it is good. The only problem is the battery backup and RAM. Batter is stays only for 1 day and the RAM should be 3GB or 4GB
