iOS 9 came out in mid-September and Apple has already released two separate bug fix updates for it. The first of those probably helped smooth the transition for people who’d downloaded the update and found themselves at a loss, although iOS 9 didn’t have any major visual differences over the previous version that should have thrown users for a loop. But with the second update, which really only addresses a handful of issues, users have to decide between fixing some minor functionality points and sacrificing a ton of memory.
According to Andy Boxall for Digital Trends, the device you’re running could actually sacrifice upwards of 66MB to install this single bug fix update. That’s a hefty price to pay in terms of memory, but at the same time, other bugs may be too be to ignore by not installing.
One of the chief problems is in how the device will disconnect certain apps from cellular access, meaning you can only use them when your device is connected to wifi. That’s not all that handy if you’re trying to access Maps because you’re lost or if you basically have to be connected to update your social media status. Basically, an issue uncovered by BetaNews shows that your phone will turn off Cellular service to an app, even if you go into the settings and tell it to behave itself (many users report that it just goes back to being “off” of cellular access when they leave Settings). This is believed to have occurred for users who had Cellular turned off for certain apps while in iOS 8, and then installed iOS 9. If Cellular was denied for those apps at the time of install, iOS 9 couldn’t recognize them and therefore limits them to wifi connection only.
This issue is supposed to be fixed with the latest iOS 9 update (iOS 9.0.2), under the change log item “Fixes an issue with the setting to turn on or off app cellular data usage.”
Of course, this isn’t the only problem with wifi/cellular connectivity, mostly for those users who do not have unlimited data plans on their phones. iOS 9 came with a new feature–which on paper makes sense–called Wifi Assist. Basically, if you’re using your phone and your wifi signal isn’t stellar, the phone will automatically switch to cellular for that app or tool you’re using. This handy feature is meant to increase your productivity by grabbing onto whichever signal is stronger, but if you’re not paying attention to the process, it could end up costing you in the end when you receive a surprise bill from your cellular provider.
