When Android contacts disappeared, you may also try to restore from backup you created for contacts before. The restore process would not be time-consuming, but will erase all your new contacts added after the data of the backup. So, you should back up your current contact list before performing a restore.
1. Open Settings app on the Android device.
2. Tap Google.
3. Scroll down the page and tap Set up & Restore.
4. Tap Restore contacts.
3. You will be presented with a list of available backups. Select the one that you want to retrieve disappeared contacts from and tap Restore.
It will start restore your Android phone from the backup and get the contacts you want.
For Samsung users, Samsung offers its cloud service to help you back up contacts. If you turn on the "Back up data" feature and tick the "Contacts (saved on phone)" option before contacts missing from your Android, there's a way to get the contacts back.
1. Go to Settings > Accounts and backup > Samsung Cloud.
2. Scroll down until you find the Restore data, tap it.
3. Check Contacts (saved on phone). You will see the last time to back up your contacts in this phone.
