In addition to the interface changes described in our previous posts, Android 12 users will get rid of one rather old and annoying feature of the notification system. For many years the strange behavior of some applications (in particular, Twitter) has taken place: when the user clicks on the notification in the notification panel, nothing happens, and after a few minutes the application starts by itself, with a large delay.
Under the new rules for the behavior of notifications in Android 12, Google prohibits applications from using such a delay, known as “notification trampoline”, and requires developers to change the notification system of their applications to the new rules.

- Find “apply update from ADB” and select it by pressing the power button.
- Check that this worked by entering “adb devices” (no quotes) in a shell or command prompt. If ADB is installed and your phone is in the correct mode, you should see an identifier for your phone and a “sideload” state reported.
- Flash the OTA via a shell or command prompt, using
adb sideload your_file_name_here.zip
where the filename is the name of the OTA image you downloaded earlier. On some platforms, you’ll need to precede adb commands with “./” for it to work correctly.
