Today Apple has released iOS 13.6.1 and iPadOS 13.6.1 to all supported devices. As the small increment in versioning implies, this build is all about fixing issues, and doesn’t bring any new features to the table. Still, that doesn’t mean you shouldn’t install the update as soon as possible.
After all, it promises to get rid of green tint on some displays, which was caused by a thermal management issue, apparently. It also fixes an issue which disabled Exposure Notifications for some users.
Additionally, an issue that prevented unneeded system data files from being automatically deleted when storage got low has been addressed, which should be especially useful for owners of older iPhones and iPads with not a lot of storage space available to begin with.
The iOS 13.6.1 update is a 110MB download, and should be ready for install right away if you check for it through Settings > General > Software Update. You may have already been notified about it.
This is likely to be among the last updates to iOS 13, seeing as how iOS 14 is due to be released this fall – and probably as soon as next month, if we go by Apple’s timelines in years past.
