I believe out of box best android version is now a myth,my A6 with oreo used to hang and lag so how out of the box android version is better?,after getting pie it changed considerably,to a great smartphone,and people say new android versions in old phones slow phones down has also become a myth,nowadays it does not get slowed down due to considerable change in technology,it has gone better,nowadays technology has transformed itself to a stage where everyone is comfortable enough,I believe so.So I believe now all can update their phones without problems,it just gets better everyday.😌😌
