Why is Android 13 called Tiramisu internally but not outside of Google?

Now, the reason for Google’s shift away from treat names is mostly to reduce confusion caused by differences in language. Resulting in problems with alphabetizing the version names. For instance, Android Nougat would technically be Android Turrón in Spanish. And the current version would technically be Android “T” in English, resulting in a dessert name starting in T in English but potentially something else in other languages. Moreover, some languages don’t use the same alphabet at all. So letters may not correspond to the proper order of releases. Even in instances where the name itself would make sense. So it’s easy to see where the confusion could come from.

What’s new with early builds of Tiramisu?

Android 13 Tiramisu, at least in its earliest Developer Preview 1 build, hasn’t fully been torn down just yet. For now, the biggest user-facing change — aside from a new photo picker that will mostly improve things behind the scenes for security and privacy — is in the Material You theming. Developers will now be able to make their app icons Material You compatible. Namely, so that a new Material You theme will apply to their icons, keeping things more consistent aesthetically. Security and privacy are also the focus of a new NEARBY_WIFI_DEVICES runtime permission for WiFi. That allows apps to search and connect to nearby devices over WiFi without requiring location permissions from users.
