Samsung galaxy core 2 is a decent android phone with good features. It has a 4.5 inch screen with android kitkat operating system. It is a dual sim phone. I found no hanging problem while playing basic games because of its 768 mb Ram. Storage is 4gb inbuilt which is sufficient to store few games and some android apps. Its main camera is 5 MP which is an autofocus camera with flash. The pictures clicked by it were clear with very less pixels. But front VGA camera was below average.
I found no problem while browsing internet on 3g and wifi both. Speaker sound is also good and loud. The best aspect I liked about it is its battery backup which is really good as it has a 2000 Mah battery with talktime upto 7 hours. So overall samsung galaxy core 2 is a nice smart phone which has all the necessary features.
