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 : https://forum.xda-developers.com/android/apps-games/app-contacts-sync-sync-contacts-photos-t3483461 Note that you MUST have a rooted device in order to run this app.
