I bought J2 from Samsungs online retail store. Got it in 3days from Samsung. The phone looks and feel premium. The rgb ring that surround camera looks stunning and is a unique approach by Samsung. Though the camera is 8 Megapixel its performance is average in daylight and at night. The display is good and colours are vibrant.
Pros:
Premium looking body.
Display is very good.
Front camera is good.
Sound quality is good like any other budget Samsung device.
Cons:
Camera performs average.
Battery does not last long.
And WiFi is buggy.
Overall its is a nice premium looking budget friendly device.
