You can get to this page for two reasons - either you already have a problem indicated in the title of the article, and now you have to frantically look for a solution, or there is a desire to avoid such troubles in the future, and, according to popular wisdom, you want what is called "lay straws" . In any case, you have come to the right place, and we will now cover all the nuances regarding the question of how to restore contacts on Android.

The factors that influenced the disappearance of contacts can be very different, and it is not at all necessary that your careless actions led to such a result (for example, after resetting the settings). The playful hands of your beloved child could still get to your smartphone and knock down the settings, deleting the phone book at the same time, some kind of Trojan wound up, until all hands reached it, unlicensed software, your other half, suspecting something was wrong deliberately deleted (deleted) contacts on Android , but you never know what else! Let's hope that not everything is so critical, and this material will help to avoid such problems, and if it happened, what happened, it will tell you ways to return the lost.

To insure yourself against irretrievable data loss, take care of this in advance by making backup copies of your contacts. After all, if applications, music and other content can be downloaded again even at the cost of considerable effort, then the loss of contacts can not only interrupt communication, but also make adjustments (sometimes with very serious negative consequences) in the business part of life. And in the event of the disappearance of the phone book that occurred as a result of a banal phone glitch or an ill-conceived backup, then the resuscitation of information is still possible, but the loss / theft of the device reduces the chances of recovery to zero.

• Register an account on Google.com.
• Open the item "Account".
• Having opened the "Security" tab, enter your phone number in the specified field.

Now, in the event that the very fluffy animal looms on the horizon, we proceed as follows:

• Select "Contacts", by pressing the "Menu" button we find the import / export field, put a tick in the "@gmail.com" field, then "next".
• We mark the item where to save contacts (better "phone").
• Click "Next" (maybe "Save Contacts"):

For example, Samsung offers an excellent Samsung Kies 2 program for its phones and tablets, which, in addition to creating backups, makes it easy to manage personal data, messages, multimedia files, etc. Among other things, using this software, you can view photos and videos stored on the phone, listen to music, etc.

The program is installed on a computer with subsequent synchronization with the Android device. A detailed description and all the necessary actions are quite accessible written at the office. site. Go to the website of the manufacturer of your device, it is quite possible that you can also find a good offer there.

Third way. It is quite possible that your contacts have not gone anywhere, but for some reason turned out to be hidden. Then you need:

• Having opened "Contacts" on your smartphone, press "Menu".
• In the list that appears, stop the selection on the "Filter contacts" item.
• In the menu that opens, put a tick in front of the "All contacts" item.

We check if this was the reason, then the phone book will again be displayed in full.

The fourth way. Some do not know that you can backup and then restore using the capabilities of the phone itself. To do this, you need to find the “Security” item in the smartphone settings menu, open it, find the “Restore and reset” line, click and in the window that opens, select “Copy data” (if necessary, you need to open this item again and activate the saved data).

Important! Do not forget to periodically make a backup using any of the described methods, this will be a reliable guarantee that all numbers will not disappear forever from your phone book, and you can return them to their place in a couple of minutes.
