bhai tu hai fool theme can do any thing just research

Yes it is no the list so in June or July you can use pie and if you want to check you can just look for j7 core or j7 neo both are same and also Samsung give every device 2 OS update and you got oreo now you will get pie

100% j7nxt will get pie update sooner or later. Samsung r saying in March so in April or my your will be running pie OS with one ui.
