About a week after the launch of iOS 16.4, Apple came up with a new update to remedy some errors and solve two vulnerabilities. iOS 16.4.1 solve the Siri errors reported by many users after updating to iOS 16.4. Scenaries in which Siri does not answer on iPhone and iPad at users' requests.
The update is available for all iPhone and iPad users in the menu: Settings → General → Software Update.
iOS 16.4.1 solves Siri errors and updates emoji
In addition to solving at least two vulnerabilities of security, iOS 16.4.1 solves the problem of interaction with siri on the iPhone, and adds color tones for Emoji Pushing Hands.

Apple does not specify anything in this update about the problems that occurred with the application Weather off the iPhone and iPad.
In the last days, the weather has had long moments in which it could not be updated on the iPhone, iPad and Mac. Those who use Widget Weather on the iPhone could only see the application background, without information about the weather.
Most likely, this problem will be solved by Apple without the need for an update of operating systems, considering that it could be a problem with the servers that update the information in the application Weather.
