I am user of samsung galaxy J7 max . I think that we should not buy samsung mobile next time because Samsung do not deliver their promise properly. People buy Samsung mobile in India because samsung after sell service is very good .His software update policy is very good .Other smartphone company give the user one major softwear update .But samsung give his coustomef two major softwear update. But samsung same Hardwear specification mobile is costly to other smartphone. But smaung break their promise with Samsung galaxy J7 max .The company do not give me major softwear update. So I can prefer you do not buy samsung smartphone next time .I was disappointed with this Samsung product.
wifi alliance does not care about any manufacturer their decision are completely autonomous. No one can help on this
android OS update at first need certification from wifi alliance, as wifi alliance certification search shows J7 MAX only certified for oreo so it is clear that it has no permission to push android pie in it
if wifi alliance issue pie certification for J7 max than only samsung is allowed to push pie update
ask wifi alliance why they are not giving permission for pie update to J7 max
