That's true, but latest midrange or even budget phones are now very optimised, have all the necessary features and can do most day to day tasks with no issues at all.
But if one is not an expert in getting these, then these outdated flagships give a lot of headaches too.
Plus, most latest flagships have nothing out of the box, unique or innovative, and are now boring with same old boring stuff, like great camera, great display, great performance, nothing more than that. No innovative or productivity stuff like Note 5 offers that actually makes life easier.
Manufacturers should now start to innovate features that actually make the life easier, more productive and efficient, like Note 5, which is the super best thing i ever had.
