Introducing Contactzilla Sync — Native Contact Management for Android Teams

Android has never offered CardDAV support out of the box. Teams that rely on shared, always-current contacts have traditionally needed workarounds to bridge this gap. Contactzilla Sync removes that complexity entirely.

Install the Contactzilla Sync app from Google Play and scan a QR code for individual deployment, or roll out to hundreds of devices via your preferred MDM platform – either way, every authorised contact appears in the native Android Contacts app while you maintain complete central control from the Contactzilla web dashboard.

How Contactzilla Sync Works for Android Teams

Contactzilla Sync is a lightweight Android client built on the respected open-source DAVx⁵ engine. It provides:

• Quick onboarding with a QR code that carries credentials and server details.
• Continuous background syncof contacts in read-only or read/write modes.
• Label-based synchronizing, so each device receives only the contacts it needs.
• Full support for major MDM platforms, including Microsoft Intune, Jamf, IBM MaaS 360 and Mosyle.

All server configuration happens in the Contactzilla web portal. Users simply scan the QR code on their Android device or receive the settings automatically through MDM – no manual entry required.

How to Set Up CardDAV on Android in 3 steps

1. Create a CardDAV connection in the Contactzilla dashboard which generates a QR code with all connection details encoded.
2. Install Contactzilla Sync from Google Play and scan the code.
3. Open the native Contacts app; the address book synchronises within seconds and continues to refresh in the background.

That is the entire workflow from an untouched handset to a fully populated, centrally managed address book.

Deploying at Scale

For large fleets, administrators generate a single configuration profile and push it through their existing MDM platform. The app installs silently, receives the profile, and synchronises contacts without user interaction. Permissions are pre-approved, eliminating pop-ups.

Who uses Contactzilla?

Emergency Services deploy read-only contact lists to shift-based devices that move between personnel ensuring critical numbers stay protected and current regardless of who’s carrying the phone.

Multi-Site Operations across construction, retail, and logistics maintain centralized contact management as teams, vendors, and locations change throughout project lifecycles.

Professional Services keep distributed workforces connected with automatically updated client and partner directories.

Frequently Asked Questions

Which Android versions are supported? Devices running Android 7.0 and later.

How does this differ from PeopleSync? Contactzilla Sync removes manual entry, offers QR onboarding, and integrates with MDM services directly. The underlying protocol remains CardDAV.

Can I restrict which contacts appear on each phone? Yes. Apply labels in the dashboard, assign them to the CardDAV connection, and only matching contacts will sync to that device.

Does the app work offline? Yes. Contacts stay on the phone and changes queue until the next connection is available.
