Android 5.0 (Lollipop) Android Lollipop review - Rolling out now

Android Lollipop (version 5.0) is the biggest update to the operating system since the move to Android 4.0 back in 2011, which unified the divergent smartphone and tablet versions of the mobile operating system. This new version of Android is designed not only with those devices in mind, but also smart watches, smart TVs and even smarter cars. That’s getting a bit ahead of ourselves though, as though Android-powered everything may be the future, for now it's only just rolling out on the most popular smartphones and tablets.

It's worth noting that smartphone manufacturers make large modifications to their handsets - tweaking the user interface to fit with their hardware design, adding new features to the operating system, and even omitting features that Google has included in the 'standard' version of the OS. For this reason you may find your updated phone doesn't look like our screenshots, but most of the functionality should still be there.

A good example of this is with the Android 5.0 update for the Samsung Galaxy S5 . As Samsung uses its own TouchWiz UI for Android, the Lollipop update isn't very different to look at when compared to the original Android 4.4 version. On top of that Samsung decided to not to implement multiple user accounts, although you do get the new task switcher and most of the new features that we talk about here, plus the improved core of the OS. As such, we can't explain how Android Lollipop will look on every handset that gets the update.

If you're updating your device we strongly advise that you reset it entirely first by backing up your data and then using the Backup and Reset option under Settings . A fresh start should liven up your device's preformance, clear away years of old apps you never use and prevent most upgrade problems.

This updated review is based around the current bugfix version of the operating system, Android 5.0.1, which should fix some issues around Wi-Fi connections and battery life. Now, we weren't overly bothered by these problems to begin with but it's good to see Google are on top of things.

FIRST LICK

If you're starting from scratch then the first new feature doesn’t take long to surface. Android 5.0 asks if you want to restore the state of another Android device on this one. This means it can install all your apps, add your various shortcuts and widgets, and place them all on the homescreen just where you like them.

It provides you with a (most probably mammoth) checklist of apps. We cut down the 101 apps installed on our Nexus 5 to a much neater list of 13 to be installed on our test Nexus 9. Greyed out icons are then placed on the homescreen in positions relative to those on our phone, with the icons filling with colour as they installed. If you reset a device you can also restore its last state back to it, so you can factory reset your device and restore everything in a few simple clicks.

Other than that, setup is as easy as ever, just pop in your Gmail address and password and you’re ready to go. Android even remembers Wi-Fi passwords from device to device, so any network details on your previous phone or tablet will be passed over to the new device.

If you’re concerned about security, and you should be, then Android 5.0 will let you lock and unlock your device using another device. Support for Bluetooth and NFC devices means your Android device will unlock instantly in the presence of, or at a tap from, your chosen item. You can of course use a PIN or screen lock pattern should you lose, or forget to bring, your chosen unlock device.

MATERIAL GIRL

Trends in graphic design don’t come along everyday, so it’s not surprising to see that Google has followed Apple in making an operating system that is simply put: flatter. Icons are simplified with more blocks of plain colour, rather than looking like little 3D rendered objects. Colour is also in vogue, with more colourful icons, more varied colours and more unusual combinations.

The operating system itself is still doing 3D rendering of course, but each object, which Google refers to as a piece of ‘Material’, is flat, like a series of pieces of paper. They can move up and down off the homescreen, cast shadows and be dragged over other objects, but they don’t have any depth themselves. If you interested in the design aspects then head over to Google's own site on Material Design .

Google has been updating the icons on its big services into its new style for some time, so Chrome, YouTube, Google+ and others are unchanged from their current incarnations, but they now match the new icons for things such as Calculator, Calendar, Clock and Downloads, see below.

All that extra colour has a new white background to shine against too. White was once a pretty bad idea for a mobile operating system, as all that brightness eats battery life, but such things aren’t as critical as they once were, and white looks a lot more approachable than black. The main example is that the app tray now has all your apps sitting in a white window, rather than just hovering over a soft-focus version of your current wallpaper.

Now all this white didn’t just appear from nowhere, it has been in the pipeline for quite some time in the form of Google Now. More and more of Google’s operating system is coming to act and look like the little cards of useful information that make up the service. Notifications are now on a white background, and the recent apps buttons brings up a rolodex of cards, one for every app.

Recent Apps (also called Overview) does provide a far clearer idea of what's going on in each app, but it's undeniably a little slower to navigate than the old pop-up list. One major change is that by default Chrome tabs each appear as a seperate app in the task switcher, rather than only within the Chrome app itself. You can change this back to the way it worked previously, but we quite like having our tabs and apps mixed in, as you can easily work back through what you've been doing in one place - seeing the appropriate Chrome tab right next to the game you were looking up an FAQ for, as an example.

Other changes include a new font, which is finer but keeps the same pleasing simplicity. Brightly coloured floating buttons make it really easy to see how you create a new contact, appointment or email. Plus the three buttons at the bottom of the screen have been simplified into a triangle, a circle and a square, replacing the curved arrow, house icon and multiple window icon that previously represented Back, Home and Recent Apps.

Simpler, brighter, flatter and more colourful, the new Android looks very smart indeed.

THERE'S NO PLACE LIKE HOME

The Android homescreen really hasn't changed all that much in terms of practicality, but then it was always flexible compared to its main rival. You can still put app shortcuts just where you want them, drag them into folders and mix-and-match these with widgets from a huge number of apps, many of which are resizable to suit your needs.

Our Nexus 9 had a 6x5 grid on each homescreen to position all this on, with 6 extra spots below in a dock for regularly used apps. While our Nexus 5 sticks with its usual 4x4 grid with a 4-spot dock beneath. New homescreens are created to the right when required and Google Now sits to the left - seen below in its tablet-friendly two-column layout.

MENU BAR AND NOTIFICATIONS

The menu bar displays the usual split of notification icons on the left and handy indicators, such as network status and battery life on the right. Swipe down though and you get an all-new combined settings and notifications menu, which consists of white cards over a darkened homescreen.

Each card can be tapped to open it in the appropriate app, dragged down to see more details if they exist. Some also have instant actions you can take, such as replying to emails, or snoozing an event reminder. This works much as before, except for its appearance and some slick animation.

Swipe down again, or just once with two fingers, and you get a handy settings shortcut panel. There’s a brightness slider, though strangely the auto brightness toggle is tucked away in the settings menu. We’d much rather have an auto-brightness button by the slider, which can then be used to tweak the level selected by the sensor.

The settings shortcut panel also shows Wi-Fi strength plus the name of the current connection which you can tap to switch connections quickly; plus there's Bluetooth too. There's buttons for Aeroplane mode, auto-rotate, a built-in flashlight (so no more flashlight apps), a turn on/off location sharing button, and a cast screen button to connect to a Chromecast easily. You can see a battery percentage charge, plus it will estimate charging time to full as well.

Tapping the volume control brings up a menu that lets you control who you get notifications from. You can quickly set this to 'All' for no filtering; or limit incoming calls, and email alerts, to only a small set of 'Priority' contacts, basically those starred in your contacts list; or turn off such notifications altogether. You can also set downtime, so you could set up a rule so that only priority notifications come through in the evenings. It's a bit confusing to use at first, and requires careful management of your contacts list to work well, but it's still a welcome extra.
