It was released 4 months or so after the stable version of Android 12. Developer Preview 2 followed later, releasing in March.{{Cite web |title=Android 13 Developer Preview 2 |url=https://android-developers.googleblog.com/2022/03/second-preview-android-13.html |access-date=March 18, 2022 |website=Android Developers Blog |language=en |archive-date=November 1, 2022 |archive-url=https://web.archive.org/web/20221101035711/https://android-developers.googleblog.com/2022/03/second-preview-android-13.html |url-status=live }} Beta 1 was released on April 26, 2022.{{cite web |title=The first Android 13 beta is available now |url=https://www.engadget.com/android-13-beta-1-release-date-170018688.html |website=Engadget |date=April 26, 2022 |access-date=April 26, 2022 |language=en |archive-date=February 27, 2023 |archive-url=https://web.archive.org/web/20230227150355/https://www.engadget.com/android-13-beta-1-release-date-170018688.html |url-status=live }} Google released beta 2 during Google I/O on May 11, 2022.{{Cite web |title=Release notes |url=https://developer.android.com/about/versions/13/release-notes#beta-2.1 |access-date=May 31, 2022 |website=Android Developers |language=en |archive-date=November 8, 2022 |archive-url=https://web.archive.org/web/20221108085736/https://developer.android.com/about/versions/13/release-notes#beta-2.1 |url-status=live }} Two more beta versions were planned for release in June and July. Platform stability was reached in June, with Beta 3. The final release of Android 13 began on August 15 when the update was made available to Pixel phones and pushed to the Android Open Source Project.{{Cite web |last=Porter |first=Jon |date=August 15, 2022 |title=Android 13 arrives for Pixel phones starting today |url=https://www.theverge.com/2022/8/15/23306058/android-13-release-date-pixel-devices-features |access-date=August 15, 2022 |website=The Verge |language=en |archive-date=October 30, 2022 |archive-url=https://web.archive.org/web/20221030161301/http://www.theverge.com/2022/8/15/23306058/android-13-release-date-pixel-devices-features |url-status=live }}{{Cite web |last=Lamont |first=Jonathan |date=August 15, 2022 |title=Android 13 now available for Pixel phones, AOSP |url=https://mobilesyrup.com/2022/08/15/google-releases-android-13-pixel-phones/ |access-date=August 16, 2022 |website=MobileSyrup |language=en |archive-date=January 12, 2023 |archive-url=https://web.archive.org/web/20230112234052/https://mobilesyrup.com/2022/08/15/google-releases-android-13-pixel-phones/ |url-status=live }}

Android 13 includes several new features intended to enhance user privacy, both user-facing and developer-facing.{{cite web |title=I/O 2022: Android 13 security and privacy (and more!) |url=https://security.googleblog.com/2022/05/io-2022-android-13-security-and-privacy.html |publisher=Eugene Liderman and Sara N-Marandi, Android Security and Privacy Team |access-date=July 11, 2022 |archive-date=July 11, 2022 |archive-url=https://web.archive.org/web/20220711091000/https://security.googleblog.com/2022/05/io-2022-android-13-security-and-privacy.html |url-status=live }}{{cite magazine |last1=Newman |first1=Lily Hay |title=Android 13 Tries to Make Privacy and Security a No-Brainer |url=https://www.wired.com/story/android-13-privacy-security-update/ |magazine=Wired |access-date=July 11, 2022 |archive-date=September 23, 2023 |archive-url=https://web.archive.org/web/20230923232834/https://www.wired.com/story/android-13-privacy-security-update/ |url-status=live }}

A new media picker is added, which improves privacy by allowing users to choose which photos and videos apps have access to.{{Cite web |title=Features and APIs Overview {{!}} Android 13 Developer Preview |url=https://developer.android.com/about/versions/13/features |access-date=February 28, 2022 |website=Android Developers |language=en |archive-date=February 10, 2022 |archive-url=https://web.archive.org/web/20220210182717/https://developer.android.com/about/versions/13/features |url-status=live }} Most apps have not implemented this picker yet. In addition, Android 13 does not allow app access to the "Android" system folder. A new permission, NEARBY_WIFI_DEVICES separated the Wi-Fi and GPS permissions that were bundled into a single "Location" setting. This change means that apps can now be allowed to search for nearby devices and networks without needing to request access to broader navigational systems.{{Cite web |title=New runtime permission for nearby Wi-Fi devices {{!}} Android 13 Developer Preview |url=https://developer.android.com/about/versions/13/features/nearby-wifi-devices-permission |access-date=February 28, 2022 |website=Android Developers |language=en |archive-date=March 9, 2022 |archive-url=https://web.archive.org/web/20220309115312/https://developer.android.com/about/versions/13/features/nearby-wifi-devices-permission |url-status=live }}

Also, a new runtime permission feature is being added to apps sending non-exempt notifications which allows users to focus on notifications most important to them.{{Cite web |title=Notification runtime permission |url=https://developer.android.com/about/versions/13/changes/notification-permission |access-date=June 11, 2022 |website=Android Developers |language=en |archive-date=June 10, 2022 |archive-url=https://web.archive.org/web/20220610123415/https://developer.android.com/about/versions/13/changes/notification-permission |url-status=live }}

Apps are now required to request permission from the user before they are able to send notifications.{{Cite web |last=Li |first=Abner |date=March 17, 2022 |title=Here's everything new in Android 13 Developer Preview 2 [Gallery] |url=https://9to5google.com/2022/03/17/android-13-dp2-new-features/ |access-date=March 18, 2022 |website=9to5Google |language=en-US |archive-date=March 17, 2022 |archive-url=https://web.archive.org/web/20220317185828/https://9to5google.com/2022/03/17/android-13-dp2-new-features/ |url-status=live }}

Small changes to dialog windows such as the Internet toggle have been added, making them fit better with the design language. The media player has been redesigned, now using the album cover as a background, and including more user controls.{{Cite web |date=March 18, 2022 |title=Android 13 DP2 Brings Redesigned Media Player & Output Picker |url=https://www.androidheadlines.com/2022/03/android-13-redesigned-media-player-output-picker.html |access-date=March 18, 2022 |website=Android Headlines |language=en-US |archive-date=March 18, 2022 |archive-url=https://web.archive.org/web/20220318114043/https://www.androidheadlines.com/2022/03/android-13-redesigned-media-player-output-picker.html |url-status=live }} The multiple users feature has been improved, with the added option of selecting which apps can be accessed by the guest user. App data is sandboxed for each user, so no information is shared.

The number of active apps is now shown at the bottom of the notifications panel; a tap on it opens a detailed panel which lets the user stop each of them.{{Cite web |last=Amadeo |first=Ron |date=August 30, 2022 |title=Android 13 review: Plans for the future, but not much to offer today |url=https://arstechnica.com/gadgets/2022/08/android-13-review-plans-for-the-future-but-not-much-to-offer-today/ |access-date=August 31, 2022 |website=Ars Technica |language=en-us |archive-date=August 30, 2022 |archive-url=https://web.archive.org/web/20220830231050/https://arstechnica.com/gadgets/2022/08/android-13-review-plans-for-the-future-but-not-much-to-offer-today/ |url-status=live }}

The new Gabeldorsche{{efn|Derivates from eponymous Harold son's name in Nordic languages (:nl:Sven Gaffelbaard).}} Bluetooth stack is now enabled by default. Support for Bluetooth LE Audio and the LC3 audio codec, which enables receiving and sharing audio between multiple bluetooth devices simultaneously; it can also improve the audio quality and battery life of the connected devices, as long as they also support it.{{Cite web |date=December 22, 2021 |title=Android 13 may finally bring full support for Bluetooth LE Audio |url=https://www.xda-developers.com/android-13-may-add-blueooth-le-audio-support/ |access-date=April 22, 2022 |website=xda-developers |language=en-US |archive-date=June 29, 2022 |archive-url=https://web.archive.org/web/20220629122229/https://www.xda-developers.com/android-13-may-add-blueooth-le-audio-support/ |url-status=live }}{{Cite web |title=New LC3 Encoder (I5f2f7627) |url=https://android-review.googlesource.com/c/platform/packages/modules/Bluetooth/+/1891675 |access-date=April 22, 2022 |website=AOSP Gerrit |archive-date=January 9, 2022 |archive-url=https://web.archive.org/web/20220109172549/https://android-review.googlesource.com/c/platform/packages/modules/Bluetooth/+/1891675 |url-status=live }}{{Cite web |title=Add new LC3 decoder (I275ea8ba) |url=https://android-review.googlesource.com/c/platform/packages/modules/Bluetooth/+/1936078 |access-date=April 22, 2022 |website=AOSP Gerrit |archive-date=April 22, 2022 |archive-url=https://web.archive.org/web/20220422033705/https://android-review.googlesource.com/c/platform/packages/modules/Bluetooth/+/1936078 |url-status=live }} This version opens the support for third-party apps to use themed "Material You" icons. Long-pressing and dragging a notification will allow the notification to open in split screen view. This feature is available on phones as well as tablets. Android 13 also adds support for WiFi 7, which is intended to decrease latency, buffering, lag and congestion.{{Cite web |last=Palmer |first=Jordan |date=2022-10-20 |title=Android 13 review |url=https://www.tomsguide.com/reviews/android-13 |access-date=2023-06-13 |website=Tom's Guide |language=en |archive-date=May 14, 2023 |archive-url=https://web.archive.org/web/20230514092135/https://www.tomsguide.com/reviews/android-13 |url-status=live }}{{Cite web |title=What is WiFi 7?

As of Beta 2, the Pixel Launcher includes a new "unified" search bar, which is able to provide search results from the internet as well as local apps and activities. It seems that Google will be expanding the capabilities of this search tool in future releases.{{Cite web |date=May 13, 2022 |title=Android 13's new launcher search lets you pin recent queries to your home screen |url=https://www.androidpolice.com/android-13-beta-2-new-launcher-search-home-screen/ |access-date=May 17, 2022 |website=Android Police |language=en-US |archive-date=May 16, 2022 |archive-url=https://web.archive.org/web/20220516224927/https://www.androidpolice.com/android-13-beta-2-new-launcher-search-home-screen/ |url-status=live }}

Android 13 allows users to change the language for a specific app, rather than doing so for the entire software. One instance of this feature is changing the language in the YouTube app from American English to Spanish.{{Cite web |title=Per-app language preferences |url=https://developer.android.com/guide/topics/resources/app-languages |access-date=Jan 15, 2023 |website=Android Developers |language=en |archive-date=January 15, 2023 |archive-url=https://web.archive.org/web/20230115173033/https://developer.android.com/guide/topics/resources/app-languages |url-status=live }}

Split Screen mode now persists through app changes, meaning it is possible to use other apps and the phone launcher, and split screen apps will stay paired together in the Overview menu. Animations have been improved, notably the fingerprint scanner glow on the Pixel 6 series. Overflow notifications on the lock screen also are housed in a dynamically sized pill rather than a bar, and the 2-line stacked clock is slightly smaller. The app label font has been changed in the Pixel Launcher, and subtle haptics have been added throughout the user experience. The Android version has been changed to "Tiramisu" in settings and the Quick Settings panel. As of Developer Preview 2, "Tiramisu" is replaced with "13". The unified search bar includes new smoother animations and transitions.

Many of the changes are from Android 12.1 "12L", such as the dock displayed on large screens, and other improvements for large format devices. These are mainly intended for foldables and tablets, but they can be enabled on phones by changing the DPI settings.

Android 13 ART was updated with a new garbage collector (GC) utilizing the Linux userfaultfd system call.{{Citation |last=Gidra |first=Lokesh |title=What's new in app performance |date=May 12, 2022 |url=https://www.youtube.com/watch?v=DYdHLqLVspY |language=en |access-date=August 16, 2022 |archive-date=August 16, 2022 |archive-url=https://web.archive.org/web/20220816141916/https://www.youtube.com/watch?v=DYdHLqLVspY&gl=US&hl=en |url-status=live }}{{Cite journal |last1=Gidra |first1=Lokesh |last2=Boehm |first2=Hans-J. |last3=Fernandes |first3=Joel |date=October 12, 2020 |title=Utilizing the Linux Userfaultfd System Call in a Compaction Phase of a Garbage Collection Process |url=https://www.tdcommons.org/dpubs_series/3671 |journal=Defensive Publications Series |access-date=August 31, 2022 |archive-date=August 16, 2022 |archive-url=https://web.archive.org/web/20220816141919/https://www.tdcommons.org/dpubs_series/3671/ |url-status=live }}{{Cite web |title=Android 13 is in AOSP! |url=https://android-developers.googleblog.com/2022/08/android-13-is-in-aosp.html |access-date=August 16, 2022 |website=Android Developers Blog |language=en |archive-date=August 15, 2022 |archive-url=https://web.archive.org/web/20220815213000/https://android-developers.googleblog.com/2022/08/android-13-is-in-aosp.html |url-status=live }} It reduces memory pressure, compiled code size, jank, and reduces the risk of killing apps because of low memory during GC. Other changes improve app startup and improve performance. Because of the Mainline project, Android 12 ART will also be updated.
