Apple(s aapl) on Thursday released its latest update to iOS 7. According to the company, iOS 7.0.4 contains some “bug fixes and improvements, including a fix for an issue that causes FaceTime calls to fail for some users.”
You should be able to download and install the update by opening your Settings menu and tapping on General > Software Update. This is much smaller than Apple’s last update, which fixed sensor calibration issues, iMessage problems, and added new features such as iCloud keychain. I’ve already downloaded and installed the update on my iPhone 5s, but I wasn’t having problems with FaceTime so I haven’t noticed anything new.
As for the rest of the fixes included in this round, the details say to check out http://support.apple.com/kb/HT1222, but so far Apple hasn’t included any information for iOS 7.0.4. So far, this seems to be a relatively minor update unless you were one of the users effected by the FaceTime bug.
