A5/A7 2017 were released with an outdated 6.0.1 marshmallow while other phones released at the same time were running nougat.
Samsung claims that it gives A series phones 2 major updates but this was not technically 2 major updates because they were released with an outdated os version an unfair update policy for the A5/A7 2017 users,we consider this cheating!
Phones that were released in the same time as A5/A7 2017 but they were running nougat

many users reported Bluetooth problem , wifi problem , hotspot problem in hadesrom,
I did not face any errors ... evey things work fine... maybe for some users .. this rom is stable for me ... now pie was released for a720s ... its easy to create a custom rom for a720f ...
thats very unfair ... we see iphone SE gets ios 13 and we have galaxy A5 2017 that released after iphone SE and we dont get Android 9 pie ... we must buy a iphone next time that we want to buy a phone ... At least they (Apple) gave respect to they customers !
so listening to your words the Samsung J530f which is less powerfull than A520f can get Android 9.....
Is just a way to push people to change phone just admit it and dont say something isnt fully right
