Google has just unveiled the fourth beta update for Android 15. While this update doesn’t introduce a plethora of new features, it pushes the software towards a critical juncture in terms of platform stability. This update allows developers to solidify all essential changes before the final public release, making it the second such milestone after Android 15 Beta 3 achieved platform stability in June. Google explains, “Developer APIs and all app-facing behaviors are now final for you to review and integrate into your apps, and apps targeting Android 15 can be made available in Google Play.”
One of the most notable changes in the latest beta update is the shift from PNG-based emoji font files to those utilizing the vector format. The primary advantage of vectors is their scalability without compromising visual quality, making them ideal for responsive design across diverse screen sizes and resolutions. This decision was initiated with Android 13, but Google maintained both formats to give developers ample time to transition from PNG to SVG vector foundations. Now, Google is ready to fully embrace vector emojis, and as a consequence, certain phones (specifically Pixels) will exclusively rely on vector emojis. There’s no denying the aesthetic appeal of crisp vector emojis, adding a touch of design revolution to the experience.
The update also fine-tunes app activity behavior, keeping apps active only when launched or interacted with by the user. With this update, Google is also making its eagerly anticipated feature, Private Space, available to the public. Private Space allows users to create a hidden space for their apps, secured by a passcode or biometric authentication. This is an ideal space to keep sensitive apps like banking, communication, gallery, and social media apps hidden from prying eyes.
Beyond these key features, a host of other enhancements are now ready for developers to integrate. Among them is a new exposure model for camera capture, significantly improving the quality of images captured in low-light environments. Another notable addition is the ability for apps to flag when they are being recorded, enhancing privacy and security. We have already provided a comprehensive overview of Android 15 since its preview days and will soon offer an exhaustive review as the public release draws closer.
