Recently, Google launched the Pixel 9 series, but it carried Android 14. This is no different from how Pixel 8 came out in 2023. The company seems to have veered off its regular monthly security update cadence. Nowadays, it only issues patches for a month when they are ready. And that is essentially that the cadence of software being released has become unpredictable.

There have been some reports that have warned of the time taken by Android 15 updates. The reports speak of the possibility of a delay in the release of the source code for Android 15. Google has not yet completed the development of Android 15. More than a month is, as an Android researcher named Mishaal Rahman reports, needed to bring the update to completion.
Google generally releases Android updates on the same day the source code goes live. However, we do point out that there is a precedent for delay—Android 12 was released to the public 15 days after the source code. The release timeline for Android 15 could also be affected by contributions from other smartphone OEMs.

One of the reasons for the delay in the release of the platforms is their stability. Consequently, Google checks for bugs to make the experience smooth and then releases the official versions. It has always done vast testing for all users to save the headache.
So far, it has been unconfirmed, and there is no date but from the look of it, October might be the month, mid-October, to be precise. The first QPR Beta build was released last week, and Android beta builds are currently available to all those who can’t wait to test the build.
