55% iPhones from last 4 years upgraded to iOS 13
Apple Inc. on Wednesday has announced that 55% of the iPhones launched in last 4 years are now running on the latest iOS 13. Some older versions of iPhones and iPads are not supported to the latest version. The 4-year metric is crucial as that's when people usually upgrade their iPhones after they stop receiving new OS updates. However, there are reports of some bugs on iOS 13 and the developers are working on to fix it.
