I have the Korean Galaxy s3 (quad core 2gb of ram) and am overall pleased with the phone. A couple of minor "complaints" though. I know Quadrant score is not accurate all of the time but, for the specs of the phone, the Quadrant score seems a bit low? It's roughly 5300 every time I run it. Correct me if I'm wrong but, it should be a bit higher? But, the main problem I'm having seems to be the High ram usage and the amount of applications open. I read the article about how unused ram is a waste of ram. I see the points in the article. But what's strange is that I have barely any applications running/open at the same time and my ram usage is 1.15gb out of 1.75gb. And when I clear the memory, it says 50 applications were (what the??) closed. Every single time after about 30 minutes or so it'll say 50 applications were closed. Also even if I clear the ram, it'll never go below 600mb out of 1.75gb. The phone does lag sometimes. I just find it strange that the ram usage is so high and there are so many "unknown" applications running when I've barely opened any applications. Forgive my "noobness". I'm still a bit new with this.
