I have a history of buying Android smartphones but several years ago switched to Apple. The reason has to do with Operating System software updates. Apple supports iOS updates for several years, but Google only supports Android updates for a couple of years. That means that you must buy new equipment or risk exposure to malware. Related to this is the notion of hardware fragmentation. Apple has a closed hardware offering each year, whereas Android is currently running on over 24,000 different hardware devices, many of which are obsolete, running on old versions of Android that have known security vulnerabilities. This chart from OpenSignal shows the dispersion of Android devices with larger boxes for larger market share:
There is a more extensive discussion of the problem of fragmentation here at VentureBeat. That article discusses many related issues and provides many other surprisingly useful charts.
