I tarted to use samsung j7 few days ago and its an ok device with nice features and and capabilities its but it has also some weakness I find which I am going to share with you.
first of all its music quality is good and speakers are really good quality and sound is pure and natural but the output from the speakers is very low and and sound is very less comes from the speakers and if you are traveling in the bus you cannot hear the ringing of your phone.its earphones are not so good quality its sound is good and music quality is fantastic but it has no strong base and can hear the normal sound and cannot enjoy the pop music with this earphones.
This is a use friendly device and there is no doubt but it has some old issue which is always found in the samsung devices that are its main problem is heating it heats a lot while surfing on internet and watching movie.another issue in it is that it hangs some times wiles using and its processor stops working and you need to restart this device then after one or two minuts it starts working fine.
Its style is really good and design is normal samsung rounded corner.but its looks so gorjious in white color and its slim body give this device to a dashing look and it feels premium and very upmarket.
It has many feature like hd video recording, led flash, 5mp front &8mp rear camera which is very less and camera quality is ok but zooming not good and not clear . it has 2g, 3h, 4g support which is good and it has two sensors one is accelarometer, proximity sensor, and it has a tiny battery of 2600 mah which is not enough and there are many other good offers in this market compared to this.
this a good phone but there are many other better option against it and its not a full value of money.
