In my opinion Samsung Galaxy J1 4g is not a good mobile by Samsung. It’s screen is good(4.50 inch). But it’s resolution is 480x800. The processor of this mobile is a 1.3GHz cuad-core processor. RAM is 1gb, which is very low. Internal storage is only 8 gb. Some time it’s get hanged for a long time. Apps are suddenly not responding . Galaxy j1 also has heating problem. Which is not good. It has a 5mp rear camera and a 2mp front facing camera. Camera is quite good. Sound is ok. Style, look is norma.
