The iOS 9 software update hasn’t quite gone without a hitch, with users reporting a number of issues with certain features.
On Apple’s help forum, several disgruntled upgradees report that the “use cellular data” option (called “use mobile data” in the UK) is causing problems.
In apps like Spotify, Apple Music, Wallet and other apps that use a data connection in the background, you have the option to stream data over 4G rather than just connecting over Wi-Fi when it’s available. But after the iOS 9 upgrade, it seems that the toggle keeps jumping back to off.
One user wrote: “The "use cellular data toggle" won't stay on for Spotify, Apple Music, Wallet, and many other apps. I originally thought it was only the apple apps that were affected but it's just random apps. It's very frustrating and hoping there's a fix soon.”
Meanwhile, some iOS 9 users on Twitter report that their contacts are not showing up in Spotlight searches, while others say that some do show up but others don’t.
The newly revamped Spotlight system is supposed to throw up contact matches when you search as well as suggestions of regularly used contacts before you’ve even typed a letter.
One fix may be to head into Settings > General > Spotlight Search > Enable Contacts, although it’s hard to know if this will work for everyone or if Apple will need to release another update to fix the issue.
News of problems with iOS 9 comes after it emerged that thousands of iPhone and iPad users' attempts to update their devices to iOS 9 were thwarted when they froze mid-update, in the so-called 'slide to upgrade' glitch.
