Bro I am currently using samsung note 5 and samsung note 4. Also I recently brought j7 max for my younger brother. If you into camera, music, removable battery, awesome screen, rom and rooting then go for note4.you have to realize that note 4 is quite an old device which runs the older touchwitz, has a bad finger print scanner and the 2k screen will not allow you to run todays game smoothly because the hardware is not optimized and with every upgrade the performance degrades.
