Google today rolled out the second and possibly last Android 13 developer preview, which includes an important new feature: apps must ask users’ permission before pushing messages.
“Apps for Android 13 will now need to request notification permission from the user before posting notifications,” Dave Burke, Vice president of Android engineering, said in the post.
Another important feature of the second preview of Android 13 is support for Bluetooth low Energy (LE) audio. Bluetooth LE Audio is a new standard that uses an audio codec called low Complexity Communication Codec (LC3) that can be transmitted at lower bit rates and with higher quality. This uses less power and leads to better battery life.
The second preview of Android 13 also includes a number of other improvements, including support for the new MIDI 2.0 standard for transmitting and controlling performance data for electronic instruments, which should provide a more analog feel with increased two-way communication, more accurate timing, and higher 32-bit information resolution.

iGeekphone has learned that the first preview of Android 13 came out in February, bringing a new theme feature and a system-wide photo picker. It’s not recommended that you install these previews right now, as these are developer releases and have a lot of bugs in them. Google is expected to release a beta version of Android 13 around April, and it might be more appropriate to do so. Google just announced yesterday that this year’s Google I/O expo will take place on May 11 and 12, and there’s sure to be a lot of talk about Android 13, which probably won’t be available until after July.
