I m using this mobile phone from last 15 mnths. At that time it was the first version of samsung galaxy j7. The reason why m I saying this as not good but not worse phone is that because I m using this from that long time still I m not happy with that. Because it hang often if more apps are installed on it. Also it was good for for first 12 mnths but now its screen fluctuate and its warranty got expired. It means these phones lasts for 12 mnths only or some more and then you need to go for samsung centre for its repair and there charges are soo high that one get confused to repair it or get a new one.
So recommend samsung to increase your warranty period to atleast 2 years so users can enjoy and send money on phones not on its repairs
