iOS 9 Updates: An iOS 9 Bug Will Make Certain Apps Useless If Not Connected to WiFi
Apple users have reported that there is an iOS 9 bug that makes their iPhone apps useless if not connected to WiFi.
Just like with the predecessors of the iOS 9, the bug makes it impossible for certain apps to run using the user's cellular data after the settings (Settings > Cellular > Use Cellular Data For) has been toggled off. The issue was first reported on Beta News by an Apple iPhone iOS 9 users.
According to the report last Sept. 28, the user said he'd tried using some apps while on the cellular network. However, even if the setting for the cellular data is switched "on," the phone still automatically reverts back to "off." The user complained that the apps can only be used while he's connected to a WiFi network.
The reports said that the issue appears to be affecting devices that have upgraded from iOS 8 to iOS 9. According to users who complained and reported it on Apple's Support forums, those with apps that are allowed to access the cellular data on iOS 8 were still able to use the same settings when they updated on iOS 9. However, those that have this setting "off" on iOS 8 were not able to switch it "on" after they updated on iOS 9.
The only way to resolve this issue for now is to restore the iPhone with a pre-iOS 9 backups, if the user has one, or if the user sets up his Apple device as a new iPhone, which will require for them to install all the other apps one by one. "Both choices are highly unsatisfactory. It might be addressed in iOS 9.0.2, but there's no guarantee that will be the case," according to the user who complained in Beta News.
The new Apple iOS was released about a couple of weeks ago, and is already being used on 50 percent of all iOS devices. Affected Apple device owners will just have to wait if the bugs are going to be fixed at all on iOS 9.0.2.
