i finally have my decission to buy my own A7 2017 series. i really like the capture of front and back. and i also compare it to s7 edge. Better is A7 series. Its because of the camera front and back 16megapixel. Then i didnt try already the ip8 water and dust resistant.
So its basically a J7 Prime in a A series body... With upgraded front camera.
I hope that the flicker issue on the A-series is already fix this time.
