The first release of Android 15 Developer Preview did not bring many changes, but they are still noticeable. The first change is in the developer settings, in the settings section — it is a switch to display the HDR/SDR ratio.
Another change — is the introduction of a haptic response when adjusting the brightness using Quick Settings. This small change will help you to know by touch when the brightness is being adjusted on your phones. There is also a keyboard vibration switch that can also be found in the Gboard settings.
Android 15 Developer Preview also offers a notification muting feature. It starts to reduce the volume of notifications when you receive many consecutive notifications from the same app. So, if you get too many notifications every morning, this feature will come in handy.
There are still many known issues with the first version of Android 15 Developer Preview — the update is only recommended for developers who are confident in their actions.
