Reuters reports today that what it says are a “significant” number of Apple customers are complaining that their iPhones or iPads are crashing when they try to install iOS 9.
Apparently many very unhappy iPhone and iPad owners were complaining on Twitter and other social media about two faults in particular that seemed to be occurring in older iPhones and iPads.
The first was simply that the iOS 9 upgrade failed during install, and had the message “Software Update Failed.” This is a fairly common problem when a new iOS is released, and is generally caused by overloaded servers as everyone in the world tries to download the newly released software at once.
With the other fault, owners of older iOS devices found that their iPhones and iPads were stalling at the “swipe to upgrade” page.
One customer told how they had waited for three hours in an Apple store and then been instructed to either perform a factory reset on their phone, or wait until Apple technicians finally release an update for the problems, of which they are well aware. That customer said that Apple’s engineers are said to be working “24/7” on a fix.
