Recently, Google suddenly released the Android 12 developer preview for Pixel phones, which is the latest generation of Android systems.
According to Google, Android 12 has improved intuitive operation, performance, and security. So what’s new in Android 12?
Although the current Android 12 is only a developer preview version, the official version will be released later this year (usually in September), and ordinary users can also experience many changes.
Foreign media Android Authority has brought the hands-on experience of the Android 12 developer preview version. Let’s take a look at some of the new features of Android 12.
The current Android 12 is a developer preview version, and the overall visual changes are not big, but there are still many small details that can be observed, and the notification center is one of them.
In Android 12, the notification center and pop-up windows are slightly changed, including the font and layout are different from Android 11. For example, when you receive an email in the notification window, there is a “z” snooze button at the bottom right. After clicking it, you can tell that the notification will be suspended for a period of time, such as 15 minutes, half an hour, one hour, or even two hours.
In addition, the notification center of Android 12 is also closely related to the system theme. If the user selects a theme color, the notification center will also have that color. For example, the Android 12 notification in the picture above has a faint blue color, unlike the Android 11 The notification is only black and white, which may be related to the previously rumored major change of the Android 12 theme system.
Google claims that apps can be opened more quickly from Android 12 notifications. If the App uses the new interface of Android 12, the App can directly trigger the activity by clicking on the notification, instead of needing to jump as it is now, which causes additional delay.
The Android 12 settings menu has also been visually modified. The search bar at the top is more conspicuous, and the options have a large Logo, which is very different from the current Android 11.
In terms of content, the Android 12 settings menu can find new security and emergency call functions, which allow you to quickly access emergency information, such as contact information, medical history details, etc.
In this functional module, there are also functions such as car accident detection, crisis alert, wireless emergency alert, and SOS call. Among them, SOS allows you to trigger emergency operations by quickly pressing or long pressing the power button, such as calling 911 and other alarm calls. This number can be modified by yourself.
However, if you enter a non-emergency number, you will need to unlock your phone to call.
The Android 12 settings menu will have more changes in the future. For example, Mishaal Rahman of the XDA Developer Forum discovered that there is a “one-handed mode”, which can be enabled on some Pixel devices, and it can provide a similar Samsung One The UI’s settings menu has a larger title layout, allowing you to touch large-screen devices more easily.
Quick settings panel
For example, some music and video player apps will use this feature. In the current Android system, media apps can generate a floating window for playback controls in the notification center. This is also a quick setting panel, but sometimes you don’t do it like a player.
In Android 12, the system allows you to turn on or off the player controls of an App. For example, you don’t want a video player like YouTube to also generate a quick setting panel in the notification center, but you want the Music App to retain such controls. Android 12 does Can be set separately.
In addition, Android 12 has also improved the style of this quick setting panel, making the buttons bigger and the cover bigger, making it easier to touch by mistake.
Quickly share the network
In Android 11, the system can already provide WiFi information sharing, but this has been further improved in Android 12.
In Android 12, if you want to share WiFi hotspots with other users, you only need to click the nearby button, which can send WiFi information to anyone.
This is a very common function of domestic Android ROM, but the native Android has not supported it. XDA developer Mishaal Rahman pointed out that Android 12 does have this feature, but it has not yet been enabled. Whether scrolling screenshots will become an official feature of Android 12 remains to be confirmed.
Touch sound feedback
In Android 12, Google further provides tactile integrated support for sound effects through vibration motors. Developers can control the intensity and frequency of vibration to enhance the immersive gaming and audio experience.
Gesture operation improvements in immersive mode
When we read e-books, watch videos, etc., we will enter the immersive mode of Android. Generally speaking, Android’s default gesture operation requires the user to slide in from the side of the screen, exit the immersive mode, and then return to the previous interface. Now, Android 12 no longer needs to swipe twice. One swipe gesture can exit the full screen immersion mode and return to the previous interface.
Project Mainline improvements
Project Mainline is a project that modularizes Android components and makes the Android system easier to upgrade. In Android 12, the ART module will also be added to the Project Mainline, and Android components have been further split, which can make Android updates more timely.
More comprehensive HEVC video encoding support
HEVC can greatly reduce the size of the video. In Android 12, even if some apps lack the HEVC encoder, the system can transcode the media captured by them, and the speed is quite good-in Pixel 4, only 9 seconds Completed the transcoding of a one-minute, 1808p, 30 frames/second video.
AVIF image format support
The compression algorithm of AVIF image format is the same as AV1 video coding, and AV1 is the latest generation of video coding algorithm. Compared with JPEG, it can significantly improve the compression quality of the image. The image quality is better under the same volume, and the volume is smaller under the same image quality. The following picture is an example.
Call content from App more conveniently
Android 12 will open a new API called “OnReceiveContentListener”. All apps can accept images, videos, audios and other content through this API. For example, users can copy a video from one app and paste it into another app. It will be more convenient to call content between different apps.
Improve multi-channel audio
Android 12 has added MPEG-H playback support in pass-through and Offload modes. In addition, the support for audio reverberation, resampling, and sound effects has been increased to up to 24 channels.
Optimize front desk service
In the current Android system, you often encounter situations where you click on an ad and suddenly jump to another app. Android 12 will prevent the foreground service from starting from the target App, and this phenomenon will be curbed.
Google is currently urgently optimizing JobSheduler’s process scheduling. Regardless of the background battery optimization strategy, it can ensure fewer background killings and a smoother App experience.
Android 12 will also delay the notifications of certain foreground services, and the notifications will not interfere with them until you complete some of the current short operations. In other words, when you are using the App, the notifications that pop up in the background will decrease.
When will Android 12 arrive?
Google has temporarily determined the timetable for Android 12. It will release a developer preview version in February, March and April, and then release the Beta version in May. After 4 Beta versions, the test will end in August, and there will be The official version of Android 12 is released.
In the above timeline, it can be seen that “Platform stability” spans the interval from the fourth Beta version to the final release, which means that Google has begun the final App, SDK, and library compatibility testing. According to the practice of previous years, the new generation of Android will be officially released in September, and Android 12 should be no exception.
In general, Android 12 still has many new features worth looking forward to. Although some interaction and appearance features have been implemented in the customized Android ROM, the underlying changes are still worth looking forward to. Let us pay attention to the development of Android 12.
