I have purchased galaxy j2 about 3 month ego. It has android 5.5.1 lollipop version and has 1 gb ram and 4.7 inches display. This phone has rear camera 5 and front camera 2 and battery capacity is 2000mah. The phone is 4g and 3g 2g and wifi connected and cpu speed 1.3ghz and internal memory There are 8 gb and expandable memory has 128 gb .My phone is very bad. The phone is very hot and it works very late. I do not like the phone to be very hot. I wonder if it sells it Dev then launched a new mobile phone. This phone is not going to do such a bad thing, the mobile is slow to do anything. If the battery service is used very poorly, then it has to be charged. This mobile Mobile phones were at a good price.
