We already know some of the new features of the big update for your mobile

At the end of November, Google finally rolled out the first developer preview of Android 16 as a starting point for the big update that mobile devices will soon receive via the final version before summer. a few hours ago released the second preview which introduces some striking new features.

The tech giant has completely changed the planned roadmap for years for the deployment of previews, betas and the final version, since until now it started in February so that the stable would be available at the end of summer.

Its Pixel sales figures in the United States and other countries were part of the reason for the change in the Android 16 rollout and that mobile manufacturers have more time to embed the big new release into your own custom layers.

One of the first new features that stands out from the previous second, according to Android Police, is the possibility of use the fingerprint sensor on the screen without it being turned on. In other words, you place your fingertip on the sensor without the phone being turned on and you will go straight to unlocking the screen.

More advanced “haptic” or vibration control of the mobile phone is available to better define the amplitude and frequency curves which will allow these vibrations to be configured to adjust their strength and duration.

Apps can now take advantage of variable refresh rate which technically allows them to adapt the frame rate of the content without having to change display modes. In theory, this should help some apps use lower refresh rates to improve mobile power efficiency.

Android's native image picker will allow you to use search in the user's gallery. In fact, Google says this feature will reach Android 16 and previous system versions through Google system updates.

WiFi will be more precise thanks to Wi-Fi Ranginga technology based on flight time (measures the time it takes for a wave to travel from the source to an object and back) rather than the strength of the signal. Google is making Wi-Fi Ranging more secure by introducing AES-256 encryption and protection against MITM attacks (when an intruder scrambles messages between connections).

Health Connect now supports activity intensity in the previous second after the first, the possibility of storing medical records was included. New data types focused on activity intensity are also added.

The improved moving back gesture so that the user does not leave the application when using it, as this usually happens more than expected. What has been done is add new APIs that help third-party app developers use the predictive animations of this system gesture.

For accessibility TalkBack ads won't be as disruptive with a new experience that recommends using other alternatives. There are more new features in Android 16, although defined for developers without having a significant presence in the second preview of Android 16, and which give way to the first beta which should be deployed next month.
