One my friend is using Samsung Galaxy J2 Ace from last 4 months and he finds out that this phone is not so good for use as it has many demerits.
First of all it’s sound quality is not so good also it’s style and design is average is compared to others.
Also it has very low battery backup of 2600mAh, 1.5GB of RAM and 8GB of ROM. Other phone of this range easily contain 2 to 3 GB of RAM with 4000mAh powerful battery and 16-32GB of ROM.
It has other demerits also like it starts hanging easily also it’s camera quality is average and it gives heating or black screen problem while using it more than 1-2 hours.
So, at the last this phone has no value of money so you should not buy this phone and consider other options if you are going to buy a new phone
