One of my friend using Samsung Galaxy S3 for 2 years but he is not satisfied with this costly mobile. at this high range you may have better option. Samsung making all product at a same category there is no change.one advantage of this phone is it’s primary camera is really good with 8MP but Samsung could be better its front camera.processor is quar core but phone doesn’t have zero lag.you can’t play large size and high graphics game smoothly and after using 2 hours heating problem comes. the most important problem is battery backup which is unable to stay for a day.
I would recommend you don’t go for brand.
