And if you accidentally delete that all-important number, you can get it back. Here we’ll show you how to use a clever feature built into Gmail to restore lost contact details.

How to recover lost contacts from Android: use Gmail

It might seem odd to look for your contacts in Gmail rather than on your phone, but as the services are intertwined there’s a good chance you’ll find what you’re looking for here. When you add contacts into your Android phone using a Google service they are synced up with the online servers to hold a record, something that proves very useful if accidents occur. You can restore any contact that you’ve deleted in the past thirty days and Chat contacts from the previous 24 hours. 

To recover the missing details you’ll need to log on to the web version of Gmail, then in the top middle of the screen select the options icon. Select the Contacts button from the drop-down menu that appears, you'll find it at the bottom as in the screenshot below.

If you don’t have a Gmail account, or at least not one that you sync your contacts to, then recovering your data might be a little more difficult. There are several third-party apps that provide this service, which entails pulling the data from the deeper recesses of your handset’s storage using a PC or Mac. From the offerings we’ve seen, Recovery Android looks to offer support for a wide range of devices, with an interface that is simple to learn.

You can also try searching Google for your specific device and the contact app you use, to see if there are any internal settings that might come to your rescue.
