I'm unsure this is true. I was certainly disappointed when I went for a Samsung S8 at launch and found it laggy and glitchy 12 months in, and unusable at 18 months. As a short term money saver, I bought a 2016 iPhone SE and was amazed to find it got 2 more years of updates before I finally decided to retire it. Between lacking support and poor performance over and over in the Android ecosystem, it became a very easy decision to move over to the Apple lock-in unfortunately. Their phones generally stay out of my way and work snappily when I need them to. It's a real shame to have had this experience, and to watch others around me have similar issues before jumping ship to Apple. I think the competition provided by the big Android vendors is important, but I just can't justify dropping money on a new device every 18 months.
