App Description

Uses root to sync your address book with high-quality contacts photos.

This way, during calls and inside the address book app, you could see who you are talking to!

The operation is almost entirely automatic, and you can choose which contacts to avoid syncing.

Disclaimer:

The app does what you can do anyway by yourself: get photos from folders that are accessible via root and later set each to the person in the address book, just like on any file-manager app (that has root capabilities).

Please check the FAQ on the official forum before using this app including the requirements to use it :

Note that you MUST have a rooted device in order to run this app.

Frequently Asked Questions about Contacts Sync (requires ROOT) APK

This variant is built for devices that report `arm64-v8a, armeabi-v7a, x86, x86_64` as their primary ABI. If your device's CPU matches, this is the smallest, fastest version to install.

Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.

Android 23 (API level 35) or newer. Older devices will refuse the install.

Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.

All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
