Apple Releases iOS 9.0.2 with More Bug Fixes

Hot on the heels of the iOS 9.0.1 update (see “Apple Fixes Slide to Upgrade Bug in iOS 9.0.1 ,” 23 September 2015), Apple has released iOS 9.0.2 with more bug fixes. You can download the update via Settings > General > Software Update, or through iTunes. For those who have successfully updated to iOS 9.0.1 already, it’s a 66 MB download on the iPhone 6 and under 50 MB on the iPad Air 1 and iPad Air 2, so it’s probably easiest to update over the air, rather than via iTunes.


The main fix is for “an issue with the setting to turn on or off app cellular data usage.” This may have been the bug behind excessive cellular data usage in iOS 9, which had previously been pinned on the new Wi-Fi Assist feature that automatically uses cellular data when Wi-Fi connectivity is poor. The Wi-Fi Assist setting is located at the very bottom of Settings > Cellular, if you want to turn it off; for some misguided reason, it’s on by default. (Apple engineers must not have to worry about data overages.)

iOS 9.0.2 also fixes a bug that prevented iMessage activation for some users, an issue where iCloud Backup could be interrupted after starting a manual backup, and a problem that caused the screen to rotate incorrectly when receiving notifications.

Apple also claims that the Podcasts app is more stable in iOS 9.0.2. Hopefully, this will fix the issue that prevented the skip buttons from appearing (see “iOS 9: TidBITS Answers Your Questions,” 16 September 2015). I was able to fix this on my iPhone by performing a clean install of iOS 9.

iOS 9.0.2 features one security fix that keeps someone with physical access to your device from accessing your photos and contacts from the Lock screen.

Many users updating to iOS 9.0.1 saw a quirk where recently updated apps had to be updated again. iOS 9.0.2 doesn’t seem to share this oddity. However, some apps may update soon, because iOS 9.0.2 adds App Slicing, which had been previously withheld from iOS 9 due to a bug. App Slicing allows developers to set up their apps so end users only download the part of the app specific to their device, reducing installation sizes.

In general, iOS 9.0.2 seems like a worthy update, particularly for iPhone users who might worry about excessive cellular data usage. We haven’t seen any reports of problems with it yet, but it’s probably worth waiting a day or two if you don’t need any of the specific fixes right away.

It is a little troubling to see two updates to iOS 9 in quick succession, which implies that Apple’s testing — even with the public beta — wasn’t sufficient to identify these bugs ahead of time. Since it seems unlikely that Apple will slow down the annual update cycle in the face of competition from Android, we may have to get used to more small updates.

When will they fix Settings auto running on startup? When will they fix the overheating and excessive battery usage?
There is no way to clean install ios9. After installing it OTA, a full delete will only remove data and settings. The OS doesn't change.

Can you be more specific about these problems? And does doing a full erase and restore via iTunes get you what you want?

I upgraded my iPhone 6 from 8.4 to 9.0.2
Went to Paypal and it had gone from English to Spanish. In the Payal forum they suggest removing Spanish or the language that appears. I did that but my iPhone went black, I dialed it and it rang but I couldn't answer. I toggled the mute switch and it vibrated. Not dead. Found an knowledgebase article telling me to hold home and on/off button and that revived my phone. Paypal was in English.
Went back to put Spanish on again and it said "updating languages" before going black again. Paypal reverted to Spanish.
I believe the black screen is an Apple bug.
There have been comments on Paypal forum for a while. It is on page 5.

Funny how the more Apple pushes public betas and being 'open' about new features/releases, the less their software works. When was the last release that went really well? And that after monthst of 'testing'!

Either the public beta "testers' are incompetent or Apple's management of bug reporting is incompetent.

So how about Apple forget about catering to a few attention-addicted geeks needing their next fix to distract from their boredom with real life? How about Apple instead focus on quality engineering? How about Apple abandon fixed update/release schedules and instead deliver when things are actually ready? Ready as in works well and works reliably. How about Apple focus on letting professionals do professional work instead of acting like engineering were some kind of social media commune activity anybody can do if only they have a Twitter account and like doing 'cool stuff'? How about Apple decide again, that things should 'just work'? How about Apple once again become Apple?

What a brilliant tirade! Absolutely _spot on_. Well said Sir. Like you, I _just want to get on with my work_.
