I have Samsung j1 and I share my personal experience. Two years ago I bought it from local store of my city that time it was available in price RS 6400. Undoubtedly it has good looks, but features are not good because it has only 512 mb ram with dual core processor so due to it, I Face hanging problem . As well as it is not good for gameing some 3d games I couldn’t play in it. It is camera quality is not good company said that it come with hd camera but it is not true .
