What kind of new features one would expect from a smartphone OS? There are brands other than computer hardware who play the product longevity, hard to understand why it's rarely the case for electronics. Innovation is not a valid excuse. In my view, the problem stems from software vendors doing agreements with hardware vendors to use obsolescence to put pressure on consumers. The difficulty is about proving that those products are designed like this.
