iOS 7 installed on 90 percent of all devices; miles ahead of latest Android release

Compared to Google's own statistics, iOS 7's install base puts the latest version of Android 4.4 KitKat to shame.

Nine out of ten iPhones and iPads are running the latest version of Apple's mobile software, according to new company statistics.

Apple's measurement of App Store usage showed just 9 percent of all iOS-compatible devices are running the older version, iOS 6, with less than 2 percent running even older versions — though, the numbers do not add up due to a rounding error.

iOS 7's install base grew by 2 percentage points from May.

Compare that to Google's figures, which has long been criticized for having "fragmentation" issues, puts the search giant's mobile platform Android to shame.

At the beginning of July, the latest version of Android 4.4 KitKat was on just 18 percent of devices, up from 14 percent from the previous month. 

That said, the wider 4.x release powers about 60 percent of all Android devices, making it the most popular major iteration of the software to date.

Fragmentation remains an important issue for mobile manufacturers to tackle. Not only do the latest software versions land with new features, they also land with security and vulnerability fixes for a platform increasingly targeted by hackers and malware writers.

But because carriers and manufacturers are reluctant to dish out the latest software goods to users, many are left behind. Ensuring that the latest software runs on the latest devices means end-customer upgrade cycles are hit, but carriers and manufacturers can hold on to their lucrative profit margins.

ZDNet's Adrian Kingsley-Hughes warned earlier this month, following the developer preview of the next-generation Android L software, that fragmentation will face the same fragmentation problems that dogged earlier versions of Android.

"The majority of Android users won't see it, and by the time it gains any real traction it will be old, obsolete, and won't be seeing any further updates," he said.

Apple is expected to release its next mobile software iteration iOS 8 later this year, around August or September, in line with the iPhone 6 launch.
