I was able to do a backup and restore of my call logs and contacts. Get the old Android device and the new Android device paired. Using bluetooth to transfer the backup file. In the old device open the app - Contacts and Phone apps. Go to Settings. Find and click Backup and Send Out to device. Then choose Bluetooth and then choose the new device as it is detected. On the new device, the backup file is automatically restored to its respective app. If not, open the particular app on the new device then navigate to the bluetooth download directory. Choose the backup file. I was able to set up, enable and test face recognition on the Asus Zenfone 5 ZE620KL. Go to Settings, just click the wheel icon on the top right of the panel. Go to Security And Lock Screen, click on Face Recognition. Make sure you're in a well lighted location. Just hold the device at arms length to your face. My test result is 8 out 10 successes. Certainly fingerprint login is more consistent and faster. I like Zen...
