If you've ever argued that your new smartphone is more reliable than what you're replacing, you now have some evidence to back up your claims. Crittercism has posted a study showing that apps running in newer versions of Android and iOS (such as KitKat and iOS 7.1) are considerably less likely to crash; you're practically inviting headaches if you stick with a phone running Gingerbread or iOS 6. The research also suggests that the Galaxy S 4 and iPhone 5 are the most trustworthy devices, while tablets of all kinds are relatively crash-happy. The findings aren't shocking when both Apple and Google have both spent years fixing bugs, and it's notable that the study only covers crashes with third-party apps -- they don't address first-party software glitches. Still, this data is as good an excuse as any to upgrade an aging handset stuck on an old platform.
