integrated support for picture-in-picture

notification sound is simplified. The
"Settings" app features a new design, with a
white theme and deeper categorization of
different settings. Android TV features a
new launcher. Google claims faster startup times from a powered-off state and
improved battery life by minimizing
background activity for infrequently used
apps.

Security
Android Oreo re-brands automatic
scanning of Google Play Store and sideloaded apps as "Google Play Protect', and gives the feature, as well as Find My Device (formerly Android Device Manager) higher prominence
in the Security menu of the Settings app. As opposed to a single, system-wide setting for enabling the installation of apps from sources
outside of the Google Play Store,this function is now implemented as a permission that can
be granted to individual apps (i.e. clients for third-party app repositories such as Amazon Appstore and F-Droid). Verified boot now
includes a "Rollback Protection" feature,
which enforces a restriction on rolling back
the device to a previous version of Android, aimed at avoiding a potential thief from bypassing security measures by installing aprevious version of the operating system that
doesn't have them in place.
