What's the best Android app for managing your phone contacts, merging duplicates, and organizing contacts into groups?

Contacts is a useful Android application for managing your phone contacts effectively. It allows you to easily organize, merge duplicates, and create groups for your contacts. This is especially helpful for users with a large number of contacts who need to keep their address book tidy and accessible. With Contacts, you can quickly find the person you're looking for, send emails or SMS messages to groups, and keep your contact information up-to-date. The app also integrates with other Google services, allowing you to sync your contacts across devices. To merge duplicate contacts, simply open the app, navigate to the 'Fix & Manage' section, and select 'Merge duplicates'. The app will then identify and allow you to merge any duplicate entries. For creating groups, select multiple contacts, tap the menu icon, and choose 'Create label' to assign them to a specific group.
