Guys when I was watching on YouTube I found it
This content shows that j7 max will get pie update between June to October but this is not official confirmation
Guys this comment is of 4 month old it means it will get one ui update this year between June to October
But.... This is not an official confirmation
Guys Jaisa ki Samsung ne kaha tha ki wo har phone ko 2 update denge to j7 max ko one ui Milna hi chahiye agar unhe update nahi dena hota to wo official confirmation dete ki J7 max one ui update nahi milega
