Recently one of my friend purchased samsung galaxy j2 so I had my hands on it.the phone has very old features and its costly too according to iys price.the phone has only 1 gb ram and 8 gb internal memory and its battery is only of 2000 mah.which means you have to charge the phone twice or thrice a day.and the processor is only 1.3ghz means we cant play big games in it.and the main problem is that it takes much time to charge.and when my friend updated his phone from android 5.1 to android 6.0 the phone always show insufficient storage available whenever he tries to download something.so on my personal opinoin I suggest not to buy this phone.
