however I didn't ask about keeping my current phone or if buying a new phone will save me money, I know that the most money saving solution in the long run is not getting a new phone. I still had an iPhone 5 before I upgraded to the 12 and it wasn't even on the release date.
Point is I DO have to switch ecosystems (not that I invested in it apart from the phone which I also got cheaper because I didn't get it on release nor did I buy any apps) and I need an android, and if im switching I want a good phone and so I might as well get the newest one or a model released the year before. So that is why I asked which of the two options I mentioned are more money saving.
