Samsung galaxy j1 ace has low storage space as it bas built in memory of just 4 gb which is very small too and only 2 gb is available to the user. A micro sd card slot is avilable to the user to store photos videos in it. As now a days quadcore is very popular but samsung has give dual core processor in this phone which runs at a slow 1.2 ghz too so this phone has very little processing power. It is provided with a tiny 512 MB of RAM which creates too much hanging problem in this phone also this phone has 5 mega pixel available at the back and 2 mega pixel availabele at the front which has very bad experience of this phon I want to recommend you to not to buy this phone.
