Samsung galaxy j1 is an android phone of 4.5inch screen with display resolution of 480 by 800 pixel. it has 1 gb RAM with internal storage 8gb. the facilities are not bad But still there are so many problems with this phone. for three or four months u would love this phone . but after that u will notice that phone is not working properly. u will be unable to play all the games u like. u cant keep more apps because the phone cannot take that much load. Functions of the phone gets slower with time. for me this phone is not suitable to buy .
