My phone is still using an older Android version - unable to upgrade any further, or receive security updates. Before you recoil in horror, consider the following: the phone is in perfectly working order, it has an excellent screen and camera, it's fast for my needs. The real horror is that millions of perfectly fine smartphones are sent to landfill because these little pocket super-computers with amazing hardware can no longer be upgraded by software. Is this a embarrassing wasteful state of affairs? Or the price of "progress" on the hardware upgrade treadmill?
