While playing PUBG in j7 duo both its display and back panel are heated to a large extent  ...This phone didn't got any update since December...I think samsung forgot that they have a phone named j7 duo and they must have to give it monthly update......

J7 DUO will get pie update on July 19 ..confirmed news ...check notice in samsung member 

Finally got the feature of using SD card as internal storage...love you samsung ❤❤❤

Frdzz I'm using J7 duo..the battery %of my phone was 29% and then I turn off it and changed the SIM card and then restarted it ...after that my battery % decreased to 19% immediately ...How is it possible????

Fingerprint scanner in my J7 DUO is very slower...It takes approximately 2 to 3 seconds to unlock ...sometimes it does not work properly...out of 10 only 6 to 7  times it works but with very slower response....please frdzzz tell what can I do???
