The Android 14 system will limit broadcasts to save resources. Broadcasting is a communication mechanism between systems and applications when critical events occur, such as when the battery power drops or the Internet connection switches from Wi-Fi to cellular network.

Mr Burke said on the show

 Android 14 once again reduces CPU activity for background apps, resulting in a 30% reduction in app cold start frequency.

 During a cold boot, code pages must be read from flash and transferred to memory before execution, so the 30% reduction is noticeable to the user.

 There are many challenges in reducing cold starts, and we naturally want to increase the number of cached processes (that is, processes in RAM) to allow more applications to be warmly started.

 But the key here is the balance, if you have too many processes cached, and they are not actually frozen, then those processes will take up processor resources and drain the battery

 Through continuous testing and training, the team can reduce CPU usage by 50% while the application is running in the background. We achieve this through some internal projects, freezing threads appropriately and reducing transfers.

Android 14 also optimizes application-related code to ensure that the space occupied by the application is reduced without affecting performance.

A cold start means that the application is started from scratch. This means that the system process only creates the application process after a cold start. A cold start occurs when an app is launched for the first time since the device started or the system terminates the app.

Mr Burke said:

 By folding return statements and performing various optimizations in the compiler, we reduced the code size by 9%. If an optimized application of about 500MB-1GB is installed on the device, the space occupied can be reduced by 50MB-100MB compared with before optimization.

Note: Continuity Camera is a feature launched by Apple that uses the iPhone as a Mac webcam and uses the powerful camera system of the iPhone to achieve effects that ordinary webcams could not achieve in the past.

In the Android 14 system, after the user connects the phone to the PC via a USB data cable, a new “Webcam” option will pop up.

Another requirement is support for USB Video Class (UVC), allowing your phone to act as a webcam on platforms like Windows, Linux, and even macOS.

However, this feature is currently not perfect in Android 14, is limited to 720P, and overall looks blurry. If you plan to use a 2x cropped view, the results will be worse.

There are also no additional improvements to the webcam in Android 14. Apple’s continuous camera has a Center Stage mode that uses AI to automatically detect a person’s position and keep the person in the center of the screen by moving and zooming the lens.

Additionally, in some rare cases, such as when there is no suitable subject in the frame, the live video starts to blur and lose focus.

Google’s upcoming Android 14 system will natively support satellite communication functions.

This Android 14 feature is not limited to Pixel phones, as long as phones with hardware capabilities can achieve satellite communication, but it may be limited to Google’s own Pixel series and Samsung’s Galaxy series in the early days.

Another developer, Mishaal Rahman, said that Android 14 introduced a number of satellite communication APIs, but the relevant code is currently hidden, so third-party applications cannot call it.

By digging through the code, Rahman said that this satellite communication service supports sending SOS emergency help text messages, sharing location information, and found a “demo mode” in the code.

Users need to open Settings > Apps > Default Apps > Notes App first, and select the default Notes app.

After the user selects an application as the default note-taking application, the user can start the note-taking application on the lock screen interface and can set a screenshot shortcut to insert directly into the note.

After the user presses the interactive button on the stylus, Android 14 can display the notes application in a floating window.

Quoting foreign technology media 9to5Google to sort out the new functions/new features of the Android 14 system as follows:

Ultra HDR

The current Android version already supports HDR video, and in Android 14, HDR photography will be further enhanced, and the Ultra HDR format will be introduced, which is backward compatible with JPEG.

Photos taken with the Ultra HDR format enabled will be stored in 10-bit high dynamic range. Due to the need for hardware support, the initial launch is limited to Android flagship models.

Google hopes that the Ultra HDR format will become the default format for the built-in camera app and third-party camera apps. Google Photos will support browsing, backup, editing, sharing and downloading in Ultra HDR format.

The Google Android team has cooperated with Qualcomm and other companies to optimize hardware and support Ultra HDR on other device forms.
Privacy and Security

In terms of security and privacy, apps can be granted access to only some/select media, while permission prompts will ask developers to explain when and why location data is shared with third-party companies.

Users will get a monthly roundup of Location Data Sharing Updates.

The new feature of Android 14 is that it supports sharing part of the screen in screencasting, allowing users to choose to share a single app or full screen.

Health Connect is now built into Android via a Google Play system update instead of an app in the Play Store.
Material You + Design

In terms of design, Android 14 introduces a new black and white theme (Monochrome).

Android 14 also improves the color fidelity of Dynamic Color, which can generate a wider range of colors and thus become more vivid.

Materials You also introduces a high-contrast mode and a medium-contrast mode.

Content-based dynamic colors allow buttons and other components to adapt to the image displayed on the screen. For example, a Now Playing page that changes color based on the current song’s album art.

Android 14 has updated the sharing interface, and the form options can be customized by developers.

Magic Compose

Google has introduced the Magic Compose feature in the default Messages app on Android, which allows the AI to generate reply text based on the message content.

Generative AI wallpapers (exclusive to Pixel devices)

Google has introduced a text-to-image diffusion model that allows users to enter prompts describing the image they want to get information about, and the system will automatically generate the corresponding wallpaper. On it home note, this feature will be limited to Pixel devices.

Google also said it has a new “cinematic wallpaper” (cinematic wallpaper), using the device’s machine learning network to convert your favorite photos into 3D images, when you unlock or tilt the device, these images will show a three-dimensional effect, giving people a lifelike feeling.

According to the latest report, the situation will change on Android 14.

Android expert Mishaal Rahman found that Android 14 has a new settings option that allows users to block apps from sending full-screen notifications. the feature enabled, full-screen notifications will be displayed on the device in the same format as other notifications.

For example, if a user blocks WhatsApp from sending full-screen notifications, voice and video call notifications will be displayed in the same way as other notifications. Users can then expand this notification to access the “Respond” and “Reject” buttons.

Depending on the display, users can block apps from sending full-screen notifications by navigating to Settings ” Apps ” Special app access ” Manage full-screen intent.

The Android 14 system is still in the early stages of development. This is only a preview version for developers, not suitable for daily use, and only available for Pixel 4a 5G, 5, 5a, 6, 6 Pro, 6a, 7, 7 Pro series devices manually download and flash, of course, you can also use the official Android emulator in Android Studio to experience.

Of course, if you are already running the DP1 version you will automatically receive the OTA update for DP2. If you are currently enrolled in the Android 13 beta program and want to use Android 14 on an enrolled device, you must first opt out of the beta program before downloading to use Android 14.

According to Google’s planning schedule, the first public beta of Android 14 will be released in April, and the next three versions will be released in the following months.

Android 14 release schedule

It is worth mentioning that Google announced that the 2023 I/O conference will be held on May 10. Of course, Google I/O usually also reveals a lot of information about the next big Android version, and it may also introduce various new hardware products.

The event will be “open to a limited audience in person and open to all users online,” the company said. Google is expected to launch more than 20 artificial intelligence products this year, many of which may be showcased at its developer conference.

Compared with the DP1 version, the DP2 version has been adjusted mainly in details. For example, it has brought a new dialog box that allows you to choose “Support allowing apps to access only selected photos and videos” or “Access all photos and videos”. Video”, or simply deny access, as shown in the image below.

Google introduced a platform API in Android 14 – Credential Manager (Credential Manager), which allows applications to log in with passwords. In DP2, Google has improved the UI style of the account chooser and made adjustments to the API based on developer feedback on DP1.

Additionally, apps targeting Android 14 require user-granted permission to be active in the background.

Google says DP2 optimizes Android’s memory management system, improving resource usage when apps are running in the background. In addition, there will be fewer undismissable notifications in Android 14, and the app store API will be improved.

According to reports, you can also set the display format you like through the regional preferences, for example, you will be able to choose the temperature unit (Fahrenheit, Celsius), the first day of the week and the numbering system according to your region.

Google announced at the MWC 2023 event that it will bring an eSIM switching tool to Android later this year. It will come with a newer version of Android (expected to be Android 14), which will be released in the fourth quarter of 2023. The feature is based on a standard developed by the GSMA and allows users to easily and securely transfer eSIMs from one device to another.

Google announced that Deutsche Telekom will be the first carrier to adopt Android’s eSIM switching mechanism, meaning users won’t have to sign up for a new eSIM and wait hours for it to activate each time they change devices. Apple already offers eSIM card transfers between iPhone, iPad and Apple Watch.

Once the feature is fully rolled out globally and all carriers begin to support it, expect more smartphones to drop their physical SIM slots. Apple already sells the iPhone 14 series without any physical SIM slots in the United States.

eSIM or eUICC is considered the next iteration of the SIM card, offering the ability to change service provider profiles via OTA without physically replacing the SIM card itself.
