Today, Google officially released the first Developer Preview (DP) for Android 15, one day later than we anticipated. One more DP build is coming in March, followed by Beta 1 in April, a second Beta in May, and then the "Platform Stability" phase begins in June ahead of the final release, which is what Google is currently revealing.
Google also said that starting in June there will be several stages they have to do to release the official stable version update of Android 15. Well specifically for this DP, Google says that they provide some additional improvements.
There are also additional performance framework improvements, and new extensions for more control over camera hardware and algorithms on supported devices as well as support for new types of data in Health Connect. Files can also be protected with custom cryptographic signatures in Android 15, ensuring that they have not been manipulated or corrupted and protecting against Malware or altering and modifying unauthorized files.
As labeled Pre-Beta, this build isn't for everyone. It is aimed at app developers to play around and make sure their apps will work well with upcoming releases. As always, the Beta builds coming from April will be easy for anyone with the Pixel to sign up with.
"Android 13 added support for connecting to MIDI 2.0 devices via USB, and Android 15 extends the support to virtual MIDI apps, letting composition apps control synthesizer apps as a virtual MIDI 2.0 device just as if they were a USB MIDI 2.0 device."
For now Google does not provide further information, but based on the images they released for the Android 15 release schedule, it is certain that this new build will be officially released for Pixel 8 Series users.
Although Google has released the Pixel 8 Series since 2023, the schedule they have proves that the company will first launch Android 15 on Pixel 8 and continue to several series below which are still given OS support.
