Apple is currently on top of the world, after reporting record iPhone sales during the last quarter. However, while Apple’s iPhone is currently ahead of the Samsung Galaxy and other Android devices in the smartphone race, Android is still getting the edge in at least one area: operating system reliability.

According to a report from PC Magazine, Android 5.0 Lollipop, the most recent incarnation of the Android operating system, experiences app crashes less frequently than Apple’s iOS 8. The information comes from a study done by Crittercism, a data company that tracked crash reports in order to compare app crash percentages on both operating systems.

Crittercism’s data shows that, on average, 2.18 percent of apps crash while running on iOS 8. In comparison, Android’s Lollipop has a very slightly superior crash rate, of 2.15 percent.

Apple has been criticized over iOS 8 since its launch in September, with many complaints focusing on the unwieldy size of the operating system software. However, Crittercism’s study provides perhaps the first numerical evidence that Apple’s most recent operating system performs less well than its predecessor. The average app crash rate on iOS 7 was only 2.02 percent.

Android, meanwhile, has markedly improved the reliability of its operating system with Lollipop. The previous incarnation of the OS, Android KitKat, crashed with nearly 2.76 percent of apps.

Crittercism’s figures show that the top two Apple devices in terms of crash reports were the iPhone 6 and the iPhone 4S. That’s not to say that iPhone 6 users should jettison their new device in favor of an iPhone 5, though. Rather, the iPhone 6 is probably just frequently associated with crashes because it is the newest and most popular iPhone on the market right now.

However, these stats may prove that iPhone 4S users would be better off sticking with an older version of iOS. After all, there is no way that a phone launched back in 2011 is still as popular as something released last year, or in 2013. And since Apple is notorious for designing operating systems that do not function well on older devices, Crittercism’s figures could be proof positive that the iPhone 4S cannot quite meet the tech specifications necessary to run iOS 8 efficiently.
