Android 15 Beta 4 版本推出

Google 剛剛發布了Android 15 Beta 4，版本號為 AP31.240617.009。

Beta 4 是Android 15 測試計劃中最後一個預定的更新，根據時間表下一步就是推出正式版，也就是跟下個月 Made by Google Event 和推出 Pixel 9 系列配合，當然也不能排除還會有 Beta 4.1 的出現。

Android 15 Timeline

這個 Beta 4 更新修復了多項問題，包括鎖屏畫面內無需解鎖操控的部件或會要求先進行解鎖的問題，Quick Settings 的對比度導致難以閱讀問題，少數情況下 Pixel設備在OTA 更新後短時間內恢復出廠設置後出現無法啟動的問題，裝置從備份還原後或會導致 App 通知設定未能還原的情況。下面是主要修正問題；

Developer-reported issues
– Fixed additional issues that caused the lock screen to intercept touch input and prompt the user to unlock the device, even when interacting with elements on the lock screen that don’t require the device to be unlocked. (Issue #348101427, Issue #345873537, Issue #349934610, Issue #348909727)
– Fixed an issue with contrast that made some elements in Quick Settings Tiles hard to read. (Issue #340944691)
– Fixed an issue that in some rare cases caused some Pixel devices to get stuck in an unbootable state if the device was factory reset shortly after an OTA system update was installed. (Issue #349860641, Issue #349978813)

Other resolved issues
– Fixed an issue where sometimes an Android Virtual Device (AVD) using an Android 15 system image failed to launch if the AVD was launched in embedded mode.
– Fixed an issue that sometimes caused app notification settings to fail to be restored when restoring a device from backup.
– Fixed an issue for Pixel Fold devices that prevented a user from continuing Face Unlock enrollment if the device was folded or unfolded during the process.
– Fixed various other issues that were impacting system stability, connectivity, performance, usability, and camera.

Bluetooth resolved issues
– Fixed a bug which prevented the Digital Car Key app from performing low latency scans when running in foreground.
– Made a fix to use custom UUIDs instead of standard HOGP service UUID in Android head-tracking service.
– Use head-tracking codec capabilities to detect transport support in LE Audio stack.
– Made a fix to prevent immediate rejection of Bluetooth pairing requests when there’s a mismatch between the API-suggested transport and the transport observed by the Bluetooth stack, potentially improving pairing success rates.
