I am guy who use a lot of phones in my life time. Before buying this Samsung Galaxy S3 phone I had used Samsung s2 and sony experia j but it was all waste because of low battery backup and low capacity to handle multi tasks. But the new Samsung Galaxy S3 is far far better than those phones in the above said features.
Even though it has got only 1 gb ram memory multitasking capacity is absolutely awesome it rarely get stuck compared to my other phones. Also this phone is suited for game lovers also it get heated really slow comparatively.
