Hii everyone, Samsung galaxy core 2 is the worst phone that I have use in my life. It has lots of disadvantages . I am using this phone for a months ago and I am very disappointed with the phone. It has very bad features . Its internal memory is only 4GB , and also the camera clearity is the worst in comparison to others. Battery backup is also very low. Sound system is also very bad of this phone . And the most worst thing about this phone is that it becomes hang whenever we are using two to three apps at the same time, the phone becomes hang. So please friends dont buy this phone go for others phones. Thank you.
