I bought Samsung Galaxy J7 in the year 2015. That time it was a pretty decent phone with quality features. Still now I am using Samsung Galaxy J7 and it works perfectly without any lags. I have also upgraded my Android to Marshmallow and the phone has become much smoother than before.Image quality is awesome with 13 MP rear and 5 MP front camera both having LED flash which may be considered as an important feature for this handset. It also supports 4G VoLTE.
Overall a decent smartphone at an affordable price. But I have been facing a problem since few months, that is the screen flickering problem. Whenever I decrease the brightness, the screen starts to flicker and when I increase the brightness the screen comes back to normal. Other than this problem there is no such issue that I have faced with Galaxy J7. Sound Reception is good and looks stylish with a 5.5 inch Super AMOLED display. Other features include the handset having Accelerometer and Proximity sensors and having a 720x1280 pixels resolution. At this price range it is a good smartphone to buy.Worth for its money I would say.
