Update not coming why?

I think Samsung should work on the j series as well because they modified the A series now is time for the j they make improvements in j4 j5 j6 and make new models now they are only concerned with there A series and not paying attention to other seri...

Samsung s7edge still is a great amd solid phone for gaming pubg will run amazing on it and camera is also good but it has't recive it android update 9 but overall it is also a good phone and camera main is 12 megapixels and front 8 megapixels and run...

I always wonder why Samsung does not gives software update to its j series phone LIKE j2 2015 model Samsung s3 is still running on android 4.4 kitcat why Samsung should give android updates to EVERY phone and I love Samsung
