Samsung J2-6 is powered by android 6.0.1., 5 inch Super AMOLED HD screen with 720p resolution, 1 gb RAM. I have been using this phone for the last 6 months and there is no problem of heating effect, hang and battery but the only problem I find in this phone is the storage. it has 8 megapixels rear camera with auto focus and sensor. And most importantly, the price of j2 2016 version is quite reasonable.
