A series come higher in the order and are more preferable to receive updates. Except for having a f/1.7 lens based primary (rear) camera, which is compensated by 16mp Sensor on A7, there is no reason to buy J7 Pro. In fact it has faster processor, IP68 water and dust resistance and has almost all the "software based/common to all" Advanced features in s series/note series like smart capture, smart stay, AOD Including SAMSUNG Pay. Go for A7 2017!
bro wait until 2018 The coming A series have infinite display and dual camera etc.. and the old a7 price also decreased when launching a 2018 series so wait and watch what will launched from Samsung waiting given more savings for you
Thanks for being with Samsung and for sharing your feedback. Sir, Samsung offers you the best value on the product released. Though the price may vary and drop to some extent after a certain period of time. We value our relationship with you. Both the devices A7 2017 and J7 Pro are finest devices in terms of performance. However they still have lot many differences in features and specifications. We would like to inform you to visit our website and check under product category about the available hardware specifications. www.samsung.com/in
