Samsung galaxy s3 is very good phone. Its function is quite smooth and it will be very fast till you don’t overload your phone. If downloaded alot of apps and games in your S3 your mobile starts hanging. Then you have only one solution that remove your battery and restart your phone. But if root your samsung galaxy S3 and after that install custom ROM CM 12 or any other .then your phone stops hanging but remember one thing rooting of any android phone voids its warranty. In the last I want thanks for your support. And thank you for reading this booring review
