Android has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Personal – Lock screen and security – Screen lock type – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.

This may not be available on all devices.

If you want to install Apps outside of the Play Store (called sideloading), then go to Settings – Personal – Lock screen and security and select Unknown sources.

This setting will allow you to download Apps onto your device that would normally be blocked in the Play store.

Note: use at your own risk.

To change keyboards (if you have additional keyboards installed), you can switch between them by pressing the small keyboard symbol in the top left of your screen. You will need to be in keyboard input mode (i.e. typing something) for this to work.

Note: you need to have more than one keyboard installed for this to work.

You can backup your phone contacts either through your Google account or by exporting it as a vCard file. Here’s how:

GOOGLE ACCOUNT

Method 1:
1) Go to your Android phone settings.
2) Click account, and make sure your Google account is already logged in your device.
3) Doing this automatically syncs all your data to Google, including contact numbers.

Method 2:
1) Open the Android Contacts app.
2) Go to Settings.
3) Choose Move device contacts to Google.

To efficiently backup all your contacts, you have to make sure that these are actually saved on your device, and not just on your SIM card.

To check if your contacts are already successfully synced or backed up on your Google account, just go to contacts.google.com, and log-in to your Google account to see if your contacts are already there.

EXPORT CONTACTS AS A VCARD / VCF FILE

1) Go to your phone’s Contacts.
2) Go to Settings and export contacts as a vCard file.
3) Alternaively, in Contacts, go to Settings and select Share. Then select which contacts you want to export. Then choose a method to export to.
4) This will collate all your contacts in one .vcf file which can be saved on your SD card or uploaded into a file storage service like Dropbox.
