Google launched Android 14 Beta 5.3 for Pixel devices today, which is the fourth update in the past month. This version is available to users participating in the beta program and contains multiple bug fixes.

Beta 5, 5.1, and 5.2 are also bug-focused updates, indicating that Google is preparing to roll out the stable version of Android 14.
The latest beta 5.3 has firmware version number UPB5.230623.009 for all eligible Pixel devices, and although the September patch has already been released, this version still uses the August 2023 Android security patch.
This version has a lot of bug fixes, and according to the official release notes, Android 14 Beta 5.3 fixes an issue related to “CallStyle” notifications that sometimes cause the app to crash. Google also fixed some issues that caused calls or carrier service to be interrupted, in addition to fixing a system issue where the phone used an “inefficient path” when imposing CPU limits on apps running in the background. Other issues affecting system stability and performance have also been resolved.
Android 14 Beta 5.3 also fixes some issues on the Pixel Fold and Pixel Tablet. One of the issues causes the taskbar to sometimes disappear when the user interacts with it. Google also fixed an issue with live wallpapers that caused animations to stutter when launching the app. Finally, the update also fixes a bug that affected the first-generation Google Fold phones, where the clock animation on the lock screen would flicker.
It is noticed that Google has been fixing vulnerabilities in Android 14 for the past month, indicating that a stable version update is close at hand, but there are recent rumors that the company will delay the update until October.
