Guide 2: Recover Deleted Contacts from Android Phones
 
In today's digital world, the loss of mobile contacts seems to be a trivial problem, but it will not disappear. With all the focus on data consumption, camera quality and social media features, it's easy to forget that contact lists are one of the most valuable features of mobile phones. It's painful to have all the contacts missing from your family, friends and work, so we've created a dedicated, comprehensive post that tells you how to recover them when needed.
 
How did this happen?
 
The most common reason for losing contacts is to upgrade the operating system of mobile devices. Whether your phone runs on iOS, Android or Nokia Symbian, manufacturers send intermittent software updates to refresh the phone with the latest features. Unfortunately, this can sometimes lead to the loss of your contacts, depending on where they are stored. Or, you may accidentally delete or delete contacts when synchronizing with new applications.

Don't worry! Your contacts may still be on your mobile phone.
 
If you are using an Android Samsung/Huawei/Sony/Vivo/Oppo/ZTE/THC/Xiaomi/LG/Meizu/Google/Nokia... device, the system sometimes hides your contacts and makes them look like they have been deleted. 
 
Fortunately, there is a simple way to check if this is the case:
 
*Open the Address Book application.
 
*Press the menu in the upper right corner (three vertical points).
 
*Select Contacts to Display.
 
*If not, please click "All Contacts".
 
*If "all contacts" are not selected, the problem should be solved.
 
 
 
Method 2
 
Recover android contacts from Google:
 
If you are an Android user, you should first check the Google account that has been linked to the mobile device. When you first create an account on your mobile phone, you may automatically accept the transfer of your contacts. If you do, the good news is that you can restore all contacts directly to your mobile phone. 
To do this, go to your inbox and select Contacts from the drop-down menu. 
If you can see your contacts, click More, and then click Restore Contacts.
 
You can also take some measures to prevent this from happening again.
 
*Start your contacts, and then select the menu/more buttons.
 
*Then navigate to Settings > Address Book > Import/Export Contacts > Export to Device Storage
 
*Select the contact you want to transfer from the list, and click Finish.
 
*Then delete the current SIM card and insert another SIM card into the device.
 
*Then navigate to Settings > Address Book > Import/Export Contacts > Export to SIM Card. 
 
*Select contacts and confirm that they are copied to your other SIM cards

 
Your contacts are now backed up to other SIM cards
 
 
 
Method 3
 
Recover android contacts with Gmail
 
If your Android device is synchronized with your Google account, the chances of restoring lost contacts will certainly be in your favor. Gmail provides a great feature that allows you to restore backups of all contacts, which can be traced back up to 30 days at most. After doing this, you can resynchronize the device with the Google account and restore all contacts.
