It is too worst thing that happened to me after buying samsung galaxy J2.when I am using it for just one to one and half hours the mobile gets heating up and the mobile gets hanging. I am very irritated when I using this mobile because it is hanging when I use it for one hour.it gets hanged and when I am chating with in facebook, instagram, what’s app.i use to take the battery when the phone hangs.at last I got angry on my galaxy j2 and selled it for just 3, 000 after my two months usage.the mobile too very slow when it gets heated up.it has just one gb of ram which is another drawback.
