Android Pie – Google’s latest version of its mobile operating system – has been released.The software introduces a new way to track usage of apps on a smartphone or tablet and lets limits be set, including the removal of color from the screen at a chosen time of the day.The ninth edition of Android also offers more powerful notifications and promises to extend battery life.But Google continues to face issues with the distribution of its updates.According to its own figures, only about 12% of in-use Android devices were running the previous version – Oreo – as of a fortnight ago.

Google says that it has worked with third-party device-makers to make it easier for them to check and deliver the updates than before.But for now, the new upgrade is only being made available to its own Pixel phones.Google always picks a dessert or confectionery-based nickname for its mobile OS, shifting one letter along the alphabet each time.

There had been speculation that the next name could be Pistachio Ice Cream, Pop-Tart or Pumpkin Pie.But the chief of Android’s London engineering team explained that there had been a deliberate decision to keep things simple.”It hints at the same goals we have with Android in general,” said Andrei Popescu.”We want to simplify the user interface, we want to make the usage simpler and more intuitive. “And I think that kind of resonates with a very simple and beautiful name like Pie.”Will it really make me use my phone less?

One of the new software’s headline features is its new Digital Wellbeing controls.These are in part a response to criticism that smart devices can be “addictive” and disruptive to our sleep patterns.A dashboard provides ways to see how much time the owner has spent using their device, with a breakdown of the hours and minutes dedicated to their most popular apps. Timers can then be set to limit usage of specific programs.

When the limit nears, users get a warning – and when it is reached the app’s icon becomes greyed out to prevent it from launching. The lockout can, however, be overridden.Wind down Mode is intended to act as a further prompt to put down the device at the end of the day.At a pre-selected time, the screen switches from color to greyscale – meaning all imagery is seen in shades of grey. In addition, the Do Not Disturb mode is activated, silencing incoming calls and alerts. Apple is introducing its own Screen Time controls to iOS 12 with a similar goal.But one physiologist said adults and children alike must be educated about the benefits of the new facilities to ensure they are widely adopted.”These are good measures, but there are still going to be a lot of people who don’t think they have a problem,” said Dr Nerina Ramlakhan, author of Fast Asleep, Wide Awake.”So, there will still need to be a lot done to educate people about the pitfalls of becoming unhealthily dependent on the use of their phones and apps.”Pie adds images to the alerts – showing both a small picture of the person who contacted the recipient, when relevant, as well as previews of any photos or other media they may have shared.

More than 14000 people volunteered to test the beta versions of Android Pie before its official release. In addition, the operating system will now allow users to reply to receive messages via the notifications themselves using a Smart Reply facility.This will attempt to predict and offer the desired response, allowing the owner to send it without having type it in themselves.

The tech firm has taken a two-pronged approach to the common complaint that devices run out of power too quickly.Firstly, it has attempted to take advantage of a common feature of modern mobile processors to minimize battery use when the display is turned off.Many CPU (central processing unit) chips now feature “big-little” architecture, whereby some processor cores priorities speed while others focus on being more power-efficient.Android Pie now schedules many of its background processes to run on the more efficient “little” cores in order to consume less power.The second approach involves trying to prevent what Google describes as “bad battery days”.To do this, the system studies an owner’s behavior in order to anticipate when they will want to use certain apps.By doing this, it can stop unlikely-to-be-opened apps using the CPU and battery to carry out tasks that could be deferred until later when the device is recharging. Huawei already offers something similar in some of its phones using its own machine learning techniques.
