Samsung Galaxy j7 , this phone is not at all satisfying according to its price range which is too high for the configuration that this phone has, except it's display there is nothing which is impressive, in 2-3 of purchase this phone showing problem with its software, this phone really hangs a lot. The processor is very slow and it's internal memory is one of the reasons of this, in this price range this phone provide very less internal memory, and the next thing which regret you after buying this phone is its battery backup. The built of phone is not soo. Strong if it slips or falls, there are full chances of display damage and it's service is also expensive and time consuming.
Sound and other features are normal, but you can definitely get much better smart phone in this price range in other brands such as MI.
