Android 5.0 promises to add a few extra pieces of security to the Android and indeed Google eco-system as a whole. From encryption to trusted Bluetooth devices, your Android device will be even more secure than it has been previously as well as being easier to access. Further down the track you will even be using your Android device as a trusted device for your Chromebook, if you use one.
In Android 5.0, the usual unlocking options: Swipe, Pattern, Pin or Password are present, although people used to the Face Unlock will have to check in the ‘Smart Lock’ section to find that option which as also added other new unlock options.
In Lollipop, when enabling your choice of lock you’re given options for displaying notifications on the lock screen :
- Show all notification content
- Hide sensitive notification content
- Don’t Show Notifications at all
The ‘Hide Sensitive Notification content’ is tied to a new ‘Sensitive’ class that developers can add to their apps, so that the app itself can choose the sensitivity of the notification. The basic Swipe to unlock option doesn’t give you these options, but it’s not surprising that an insecure unlock option wouldn’t present options to hide sensitive notifications.
Once you set either Pattern, Pin or Password unlock, you get more options in the Security menu : Make Pattern Visible, Automatically Lock and Power Button Instantly Locks. The Automatically Lock option lets you select an interval (5, 15, 30 Seconds or 1 minute) after which the phone will lock.
Lollipop now introduces Smart Locking, or more correctly Unlocking options. Under Smart Lock you’re now able to select various options to unlock your device. You can choose from two options : Trusted Devices or Face Unlock. Under Trusted Devices, you can choose between Bluetooth or NFC. NFC obviously lets you program a tag, or NFC enabled device (NFC Speakers, Headsets etc, such as Sony sell), while Bluetooth lets you choose from connected or paired Bluetooth devices. This includes Android Wear as well as Bluetooth headsets (My Jabra Sports headset is now a trusted device).
Once Paired your device remains unlocked. You can turn the screen off, but when you power it up, you simply swipe the lock screen away, no pin/password/pattern required. You can choose to manually lock it by long pressing the lock icon, at which time you will then need to enter the pin/password/pattern you had set.
Face Unlock, hasn’t changed terribly since its introduction in Ice Cream Sandwich, although the mechanism to add a face is now a little cleaner and has had a Material Design overhaul. Once selected you’re invited to set it up by holding the phone so that you face is within a face shaped row of dots – the phone basically maps your face and then you’re done.
With Face Unlock selected, when you swipe to unlock the camera will quickly try to recognise your face. When it works it’s fast, really fast – but if it can’t detect you it falls back to a Pattern, Pin or Password unlock.
You can reset or do the face match again in different lighting conditions etc in the settings to improve facial recgognition, but in the end it either works or doesn’t.
Android is pretty secure, but in the lead up to the release of Android 5.0, Google announced some big changes were going to be coming with regards to on-device encryption. The option to encrypt your device has been present since Android 2.3, but it’s evolved over the intervening releases and in 5.0, it will be enabled by default. In the Android 5.0 Developer Preview, Encryption isn’t enabled by default but this should change once the full release pushes out.
Security wise Android is looking pretty good. The usual Security settings from previous versions of Android are here, including the ability to load Digital Certificates for networks etc. There’s just a few more options in security now.
