Remember that iOS 9 security issue that allows someone to bypass the iPhone lock screen using Siri and access your contacts and photos? And how some folks thought that it wasn't real? Well, Apple sure did, as the latest iOS 9.0.2 update includes a fix for the problem. Apple said that because of the security hole, "a person with physical access to an iOS device may be able to access photos and contacts from the lock screen." It addressed the issue by "restricting options on a locked device," meaning users will no longer be able to exploit Siri to access those areas.
With iOS 9.0.2, Apple also squashed iCloud backup issues, iMessage activation problems and a bug with mobile data settings. Finally, it fixed a screen rotation issue and improved the security of Podcasts. Want the update now? Don't worry, you should get a notification that it's available if you haven't already.
