Even with the bugs and problems reported with iOS 9, the latest mobile OS from Apple has hit a record level of adoption, while last year's Android 5.0 Lollipop is still rolling out at a fraction of Apple's upgrade rate. 

The company announced this week, based on figures from the Apple App store as of Monday, that adoption of the company's just-released iOS 9 has already hit an incredible 61 percent. That's faster than the adoption rate of last year's iOS 8.

However, as ZDNet noted, the fact that iOS 9 is a much slimmer upgrade package and can actually fit on the most popular 16GB iPhone models probably helped adoption a lot. Apple's iOS 9 takes up about 1.3GB storage as compared to the 4.58GB behemoth that was iOS 8.

That 61 percent adoption in just a few weeks is certainly much faster than Google's Android Lollipop, which is at less than half of the adoption across Android devices compared to Apple's just-released mobile operating system.

Android Lollipop was released late last year. According to Google's latest figures as of Oct. 5, it is only on 23.5 percent of Android devices, and that's taking Android 5.0 and Android 5.1 Lollipop together.

Apple knows how to build an ecosystem of hardware and software in which people want to upgrade at the first chance, despite the bugs reported by users. The Android OS ecosystem, on the other hand, remains incredibly fractured, with Android 4.4 KitKat remaining the most popular version of the OS at 38.9 percent. Meanwhile, Android Jelly Bean, which is several years old at this point, remains on almost a third of Android devices at 30.2 percent.

To be fair, Google's operating system is running on all sorts of devices, from premium 2015 flagship smartphones to the most basic touchscreen devices that cost almost nothing in comparison. These devices also come from a laundry list of manufacturers all across the world.

The adoption rate for Android will likely never be as quick or as uniform as Apple's, but in exchange, Android, in all its flavors, is much more ubiquitous.
