The proliferation of devices, mobile or otherwise, requires the possibility of retrieving information at any time. Receive your e-mails on your tablet, send them to your computer while you save an appointment on your smartphone…

To do all this in a simple way, we must of course talk about “synchronization”- all our accounts are accessible and updated simultaneously on all devices. Here are some tips to easily perform this procedure.

Probably not the first time you find yourself managing your contacts and I’m sure you’ve already encountered a very frequent problem- duplicate contacts in your contacts. Don’t want to get your aunt’s number three times in a row?

How to sync contacts on Android?

Synchronizing your contacts is important to keep your Android phone’s contacts up-to-date and not lose phone numbers and e-mail addresses of friends and colleagues after getting root permissions or buying a new smartphone.

When setting up your new smartphone, you must have created or linked a Google account to your device. In this way, thanks to synchronization, all changes will be updated both on the device and online.

To synchronize your contacts, you have no choice but to access the Settings menu on your device and click on Account.

You will find a list of all the applications that can be synchronized- Facebook, Linkedin, Google+, Twitter, WhatsApp, Telegram, etc.

Select your Google account, and sync your contacts, calendar, drives etc. on your Android phone.

How many times have you seen a Facebook post from a friend asking you for your number because he has a new phone and lost contacts? Don’t be like your friend; here’s how you can synchronize your contacts between all devices, regardless of whether you use Android or iOS (or both).

How to import your contacts on a new device?

If your contacts are synced with Google, you only need to sign in with your Google account on the device.

The best way to import your contacts from the old to the new Android device is to access the old device settings.

Click Import / Export and copy all contacts to the SIM card.

Once the SIM card is inserted into the new device, go to the previous menu to export your contacts or, better yet, your Google account.

In this way, you are sure to always have them available even if you lose your smartphone.

However, the situation becomes more complicated if the new smartphone supports a different size SIM card (for example, nano). In this case, you can count on:

  • Bluetooth
  • Direct WiFi (note, not all devices support this feature)
  • PC

Before connecting to the PC, export the contacts from the old device as a vCard file (VCF).

It is a file format that collects data such as names, phone numbers, e-mail addresses and other similar information that can be imported to other devices or directly to your e-mail service.

Just transfer the .VCF file to the new smartphone and import it from the contacts application.

How to sync contacts with iCloud

Reserved for Apple users, iCloud is a free service for synchronizing data across multiple devices. If the iCloud account already exists, with the data saved on it, just a simple connection. Instead, you need to create an account and accept data sharing. Once the account is set up, in the “Settings” section you can choose the items to synchronize.

How to remove duplicate contacts on Android

How many times have you sent a text message to a friend to give him the name of the pizzeria where the meeting was held without receiving any reply before realizing that you sent the message to an old number?

Are you guilty?

Duplicate contacts!

Fortunately, Android offers several solutions to this problem.

1. Manually from contacts

Go to the address book and hold for a few seconds on the contact you wish to delete. Once the menu is displayed, click Delete. You can also access the directory configuration menu and click Organize contacts> Merge duplicate contacts.

2. From your PC by logging into your Gmail account

From your PC, you can delete duplicate contacts from your address book by opening Gmail and clicking on the contacts displayed in the drop-down menu at the top right. Then click on More and Search and merge duplicates and Google will show you contacts with shared names or phone numbers. You can then decide to delete them or merge them into a single object.

3. With a dedicated app

If neither of the two previous methods convinces you, you can still open the Google Play Store and download a dedicated application such as Duplicate Contacts or Contact Optimizer. These are two easy-to-use apps that will guide you through your contacts by providing a list of duplicate contacts. So you decide whether to eliminate them or not.

Another noteworthy application is Phone Clone. This service allows you to transfer not only contacts but also videos, photos, messages and applications from one Huawei device to another. I used it to transfer my data from a P9 to a Mate 9 and it worked perfectly.

Do you use other applications to find and delete duplicate contacts in your address book?
