The mobile serves to do everything, from being you Lantern even you 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 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 import and export 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 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.

Applications for sync profile photos from social media with those of your contacts on the mobile are a bit in the doldrums after Google+ disappears and Facebook established more limits on access to your data, but there are still some who try, like Cozy.

Cozy try link mobile contacts with your Facebook friends, then being able to download your profile photos. To do this you need to log in to Facebook (or download your friends as CSV and upload them to the app), and then you must link them with your contacts to download. The app is a bit slow, but working it works, more or less.

Set Contact Photo


What if you prefer to use the profile picture of a WhatsApp or LinkedIn contact? As we mentioned before, it is not a process that can be automated now (unless you are rooted), but Set Contact Photo has found how to achieve it with a little help from you. In other words, it is not an automatic process.

The app shows you your contacts, and in each of them you will find buttons to go to their profile on WhatsApp, Facebook, LinkedIn, Viber or Instagram, being able to later take a screenshot with the integrated tool to crop the profile photo. It is not a very elegant solution, but functional.

Accounts is primarily an application for identify calls and block spam calls, although it can also keep your contacts in sync and up-to-date. 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.
