Apple’s upcoming iOS 26 release, scheduled for September, introduces several new productivity features that promise to enhance the end-user experience. However, these updates can also raise important questions for organizations that rely on the Movius MultiLine app for compliant communications.

This article clarifies the impact of iOS 26 on the Movius MultiLine app and outlines what you need to know before upgrading.

Key iOS 26 Features and Their Implications

Call Screening

What it does:

The new Call Screening feature (user-controllable via iOS settings) inspects incoming calls against your device contacts. If the number is not in your device contacts, iOS 26 prompts the caller to disclose information before the call is connected.

Impact on Movius MultiLine App:

• Minutes Mode: No impact. In minutes mode, all incoming calls are routed through a Movius-powered service number that is already stored in the user’s device contacts as a Movius Service Contact. As a result, iOS 26 will not trigger call screening for these calls. If, for any reason, the user has deleted the Movius Service Contact, the Movius MultiLine App automatically recreates it.
• Data Mode: No impact. Data mode calls in the Movius MultiLine app are not subject to iOS call screening.

Conclusion: Users can continue to rely on both minutes and data modes without disruption.

Liquid Glass (UI Updates)

What it does:

• Introduces several new UI and visual enhancements to improve the iOS 26 experience.
• Changes the way applications are expected to support certain types of search and interface interactions.

Impact on Movius MultiLine App:

• Current and upcoming versions of the Movius MultiLine App are fully compatible with iOS 26.
• No compatibility issues or negative UI side effects.
• Apple requires developers to adopt Xcode 26 (the updated development platform) starting in 2026.
• Adoption of Liquid Glass UI features is under product review. Movius will selectively introduce enhancements in line with Apple standards as part of the 2026 roadmap.

Conclusion: iOS 26 does not disrupt app functionality or prevent Movius from publishing new versions. Liquid Glass adoption will follow at the right time.

Xcode 26 and Intune SDK Updates

What it does:

• Xcode 26 is the latest version of Apple’s Xcode framework for iOS development.
• It introduces several enhancements and benefits for application development.

Impact on Movius MultiLine App:

• Movius MultiLine App currently uses Xcode 16 and plans to upgrade to Xcode 26 as part of the October release.
• Movius MultiLine App will add support for T-Mobile’s T-Satellite feature powered by Starlink as part of the October release. This requires upgrading the Movius MultiLine Application to Xcode 26.
• When we upgrade to Xcode 26, we have to upgrade our Intune SDK to the latest compatible version.

Conclusion: These updates will not affect end users. MultiLine will remain fully compatible with iOS 26 and earlier versions, with no action required from users.

What This Means for You

• No action required: Customers and end-users can safely upgrade to iOS 26 when it is released in September.
• No compliance concerns: Call screening and Liquid Glass do not interfere with MultiLine operations or communication logging.
• Future-ready: Movius will continue to evolve the MultiLine App to align with Apple’s development roadmap, without compromising stability or compliance.

Notice

Apple will include important policy changes as part of the iOS 18 release.  The public release of this version is expected to be between mid to late September. Movius will publish a new version of the Movius MultiLine Apps for iOS before iOS 18 is released. 

Action Required

For best experience and to avoid service interruptions, Movius recommends all customers and their employees using Movius MultiLine apps on iOS to update their MultiLine apps and to upgrade their devices to at least iOS 17. See How do I update my MultiLine app? 

Once iOS 18 is released, Apple will not allow users on iOS 16 to get any app updates, including Movius MultiLine.

• Users can avoid this situation by upgrading to iOS 17. 
• For devices that do not upgrade from iOS 16 the Movius MultiLine App will continue to work on iOS 16 until the end of the year.

Version History

In November, we released version 4.05.01 of the mobile apps (iOS, Android) which included changes to standardize the phone number format to conform to the E.164 format. These changes included pre-populating the country prefix on the dialer. 

In result, when dialing short codes (including emergency numbers 911 and 988) you must manually delete the country prefix before dialing the short code. We realize this can be an inconvenience, so we are working on an update that will automatically remove the country prefix when dialing short codes. We plan to release this update in the next 2 weeks. 

The following bulletin addresses our support for Click-to-Dial functionality affecting all iOS versions of MultiLine Apps (Movius MultiLine, Movius for Blackberry, MultiLine for Intune, and T-Mobile MultiLine). 

What is Click-to-Dial?

The Click-to-Dial feature is extremely helpful to our users because it automatically detects and renders phone numbers as links, and allows users to simply click the link to initiate a call using MultiLine. This includes calling contacts, numbers in emails and other apps, and conference bridges.  

For conference bridges, Click-to-Dial allows users to avoid dialing lengthy numbers, because with a single click, MultiLine apps dials the number, characters (including # or *) and additional digits in the dial string, such as Conference Codes and PINs.

Issue Background

This feature worked perfectly until iOS 15.4.  

• In iOS version 15.4, Apple no longer accepted automated dialing strings that have the # (Hash or Pound sign) as a dialed digit.
• This affected contacts or Click-to-Dial links that are used to log into login to conference bridges. These often use the # as part of the dialing string.
• This affected Movius users that use “minutes” mode for outbound calls. It did not affect users that use “data” mode for outbound calls. See Call Settings.

To work around the issue, we implemented logic in our application to recognize when a user was on iOS 15.4 and transform the '#' to a ',' in the dial string that gets passed to the native dialer.  While it was not a perfect solution, in many cases it allowed the calls to complete, apart from a minor delay in connecting the call.

Issue Update

• Apple has now released iOS versions 15.5 and 15.6 where the issue with passing # to the native dialer has been corrected.  
• This means we can remove the workaround and allow MultiLine Apps to dial conference codes as intended. However, any users who haven't updated to iOS 15.45 or 15.6 will face issues dialing conference codes as described above.

Resolution

• Movius will be deprecating support for Click-to-Dial on iOS 15.4. 
• To avoid issues, users should upgrade to iOS 15.6 (current available release).
