The latest update - iOS 13.1.3 - is seemingly created to fix a number of these complaints.
iOS 13 introduces some much-needed quality of life improvements, and a tonne of bugs. On iPadOS 13, iPad users can fit more app icons on the home screen, shrink the virtual QWERTY keyboard, use the native swipe to type feature on the keyboard, and receive desktop websites by default on Safari.
Apple recently released iOS 13.1.3 and iPad 13.1.3 for iPhones and iPads. If you've ever missed a call because your iPhone never rang or even vibrated or if you've had problems pairing your Apple Watch, then this is the release that fixes those. It also comes with a fix for iCloud Backup where some apps failed to download on iPhones.
iOS 13.1.3 also fixes issues for users who couldn't pair their Apple Watch successfully.
With the iOS 13 update, Apple has added a native Dark mode, reduced the size of app downloads and updates making them faster, and apps will now load on the iPhone up to 2 times faster. As a matter of fact, Apple has said that the 50 percent figure had arrived within just 26 days of the launch of iOS 13. Bugs that caused issues with the Apple Mail app, Voice Memos and Health apps have been addressed.
