Samsung isn't yet done with the J series, and it shouldn't be a surprise given that there are a few numerals the company hasn't used between Galaxy J2 and Galaxy J7. So, today we have the Galaxy J3 which comes with a 5-inch HD super AMOLED display running on a quad-core processor with 1.5GB RAM, 8GB internal storage which is expandable upto 128GB running Android 5.1 Lollipop.
So the Galaxy J3 sits between the Galaxy J2 and Galaxy J5 in terms of specs. It comes with an upgraded display and better cameras than the J2. You have 8MP/5MP shooters here alongwitha 2600 mAh battery.
At present the Galaxy J3 has been just launched in China and supports their FDD LTE bands. But we expect a dual-SIM variant with a wider LTE band support. There is no word on pricing or a global rollout but the J3 will be available in a trio of colors - black, white and golden just like the other J series devices.
