26 mayo, 2021

The mobile is used to do everything, from being your flashlight to your calculator going through a thousand and one more functions, without forgetting that it also serves to call your contacts. Contacts that can end up becoming an indecipherable mess unless you take the time to organize them.

That is precisely what you will find in the six applications on our list: applications to manage Android contacts, performing maintenance tasks such as removing duplicates, synchronizing profile photos or importing and exporting contacts.

Google Contacts


Contacts is the name given to the Google contacts application and therefore the default on Pixel, Nexus, Android One mobiles and others with a stock-like experience. Unlike Phone, Contacts can be installed from Google Play in other terminals even if they have Samsung One UI, EMUI or others.

Simple in appearance, Contacts has a Suggestions section where you can combine duplicates or find suggestions of people to add from the people you write to in Gmail. From its settings it is also possible to import and export the contacts.



Contacts Optimizer


If you are looking for something a step beyond finding duplicates, you will find it in Contacts Optimizer, although it will cost you 1.92 euros to get the Pro version. The free version allows you to edit contacts and find and delete duplicates.

This optimization is precisely the most interesting part of the application, as it allows you to sanitize the phone numbers of your contacts including the country code successfully, find contacts with missing important data, clear empty fields from all contacts, or move contacts between different accounts.

Accounts is primarily an application to identify calls and block spam calls, although it can also keep your contacts synchronized and updated. For this you can link your accounts Facebook, Google, Instagram, Twitter, LinkedIn and VKontakte.

As for the synchronization of contacts, the truth is that the process works quite well and the process is comfortable to find mobile contacts in other social networks, with the advantage that the photos will be kept updated periodically. The bad news is that as soon as you uninstall the application, the magic will end, returning the contacts to their previous photo.
