Throughout life, there always comes a time when you lose all your Contact and starts putting them back in one by one. To avoid that, they started saving them to the SIM card. However, that method is old and inefficientIf we want to save contacts so as not to lose them again, or transfer them between Android, iPhone, BlackBerry, etc. mobiles, it is best to use the contact sync through our Google account, which is extremely simple and fast. Also, when you edit a contact, the changes will be applied all your devices.
Synchronization with Google account is something essential on any Android smartphone. The truth is that to download apps we even need to do so through our account, so considering having an Android without an active Google account is crazy. Once we log in, even if we don't realize it, our account synchronize Many data, such as calendar, contacts, and other items. Sometimes, however, these options are not active, so we must do so manuallyLet's see how to activate contact synchronization and how to always have them saved in our Google account.
Activate and understand contact synchronization with Google

1.- We access Settings and Accounts
The first step is to access the section of accounts of our device, something that may differ slightly depending on the version of Android we have. In any case, generally, we must access Settings > Accounts > Google. Until Gingerbread and Honeycomb, Accounts was a folder within Settings. Starting with Ice Cream Sandwich, Accounts is no longer a folder, it's a section within Settings. The goal is to get to Google, within Accounts, within Settings.
2.- We access the corresponding account
At this point, we'll most likely be shown the accounts we're logged into Google with. It's easy for only one to appear, but that's not necessarily the case. Click on the one we're most interested in, personal account, if we have several. We may be shown a message saying "Sync is disabled", but that does not mean we cannot perform a punctual synchronization.
3.- We start the synchronization
Right now we will be looking at the different elements that we can synchronize, such as the calendar, the Contact, Google Drive, Gmail, Google Reader, Browser, etc. Depending on the operating system version, the process to synchronize may be different, but in any case, it is usually only necessary click on the element to sync, in this case, Contacts. We can also press the Android Menu button and select Sync now, which will synchronize all elements.
4.- We wait for the process to finish
Obviously, if we have a lot of contacts, and we have never synced before, it will most likely take a few minutes synchronize everything. We wait for this to finish. Although we haven't mentioned it, it is absolutely necessary to have Internet connection so that our contacts can be synchronized with our Google account.
From now on, every time we create a new contact and we are asked to select the directory in which we want to do it, we must select our Google account. On the other hand, we must not forget to repeat this synchronization process from time to time, in order not to lose the new contacts we have added. If we have synchronization Always active on our smartphone, and the process is marked as automatic, we won't have any problems, as it will do it automatically. However, if it doesn't, we'll have to do it manually from time to time.
This same process is useful if we acquire a new mobile phone and want to do it in reverse. From our Google account we will synchronize All contacts can be transferred to our smartphone without wasting time or copying them to the SIM. And the same can be done with any iOS device, BlackBerry, Windows Phone, and others. To transfer contacts from another smartphone to an Android or from an Android to another smartphone, we must do it through the Google account, since it is the simplest method. Keep in mind that if you disable synchronization Contacts, those that were in the cloud may no longer be visible on the mobile; when you reactivate it, restaurant automatically.
