This the worst flagship phone launched by samsung because it just has 12 megapixel camera which has become very old and the trend is for 21 megapixel.
Battery is also 3600 mAh which has become old and trend is of 4500 mAh.
Secondary camera is also 5 megapixel which has become old . Sim cards are only 3G supported . So is a phone not to buy.
