Pixel phones, including the first-generation

were included, after being granted an extended warranty period which guaranteed Android version updates for them for at least 3 years from when they were first available on the Google Store. A total of six beta or release-candidate versions were released before the final release.
The beta program was expanded with the release of Beta 3 on May 7, 2019, being made available on 14 partner devices from 11 OEMs; twice as many devices compared to Android Pie's beta.
Beta access was removed from the

Huawei Mate 20 is a line of Android phablets produced by Huawei, which collectively succeed the Mate 10 as part of the Huawei Mate series. The flagship models, the Mate 20 and Mate 20 Pro, were unveiled on 20 July 2018 at a press conference in ...
on May 21, 2019, due to U.S. government sanctions, but was later restored on May 31.
Google released Beta 4 on June 5, 2019, with the finalized Android Q APIs and SDK (API Level 29). Dynamic System Updates (DSU) were also included in Beta 4. The Dynamic System Update allows Android Q devices to temporarily install a Generic System Image (GSI) to try a newer version of Android on top of their current Android version. Once users decide to end testing the chosen GSI image, they can simply reboot their device and boot back into their normal device's Android version.
Google released Beta 5 on July 10, 2019, with the final API 29 SDK as well as the latest optimizations and bug fixes. Google released Beta 6, the final release candidate for testing, on August 7, 2019.
On August 22, 2019, it was announced that Android Q would be branded solely as "Android 10" with no codename, effectively ending the practice of alphabetically codenaming major releases based on names of confectionary products (including brand names), arguing that this was not inclusive to international users, due either to the aforementioned products not being internationally known, or being difficult to pronounce by speakers of certain languages. Additionally, Android VP of engineering Dave Burke stated that most desserts with a name beginning with the letter Q were exotic, and that he personally would have chosen

Features
Navigation
Android 10 introduces a revamped full-screen gesture navigation system and new app open and close animations, with gestures such as swiping from either side edge of the display to go back, swiping up to go to the home screen, swiping up and holding to access Overview, swiping diagonally from a bottom corner of the screen to activate the
Google Assistant, and swiping along the gesture bar at the bottom of the screen to switch apps. The use of an edge swiping gesture as a "Back" command was noted as potentially causing conflicts with apps that utilize
sidebar menus and other functions accessible by swiping. An API can be used by apps to opt out of handling a back gesture within specific areas of the screen, a sensitivity control was added for adjusting the size of the target area to activate the gesture, and Google later stated that the drawer widget would support being "peeked" by long-pressing near the edge of the screen, and then swiped open. The traditional three-key navigation system used since
Android "Honeycomb" remains supported as an option, along with the two-button "pill" style navigation introduced in
Android 9.0 Pie.
Per Google certification requirements, OEMs are required to support Android 10's default gestures and three-key navigation. OEMs are free to add their own gestures alongside them. However, they must not be enabled by default, they must be listed in a separate area one level deeper than other navigation settings, and they cannot be promoted using notifications. The two-key gesture navigation system used on

is deprecated, and may not be included on devices that ship with Android 10. However, it can still be included as an option for continuity purposes on devices upgraded from Pie.
User experience
Android 10 includes a system-level
dark mode. Third-party apps can automatically engage a dark mode when it is active.
Apps can also present "settings panels" for specific settings (such as, for example, internet connection and Wi-Fi settings if an app requires internet) via overlay panels, so that the user does not have to be taken outside of the app in order to configure them.
Privacy and security
Several major security and privacy changes are present in Android 10: apps can be restricted by users to only having access to location data when they are actively being used in the foreground. There are also new restrictions on the launching of activities by background apps. For security (due to its use by

malware) and performance reasons, Android 10 Go Edition forbids use of overlays, except for apps that received the permission before a device was upgraded to Android 10.
Encryption
In February 2019, Google unveiled
Adiantum
''Adiantum'' (), the maidenhair fern, is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "un ...

ARM Cortex-A7 CPU. Therefore, device encryption is now mandatory on all Android 10 devices, regardless of specifications, using Adiantum if their CPU is not capable of hardware-accelerated AES. In addition, implementation of "file-based encryption" (first introduced in

, manufacturers must support these updates for specific modules, while the remainder are marked as "recommended" but optional. Selected modules within this system use the new APEX package format, a variation of
APK files designed for housing and servicing low-level system components.
Scoped storage
A major change to storage access permissions known as "Scoped storage" is supported on Android 10, and will become mandatory for all apps beginning with Android 11. Apps are only allowed to access files in external storage that they had created themselves (preferably contained within an app-specific directory), and audio, image, and video files contained within the Music, Pictures, or Videos directories. Any other file may only be accessed via user intervention through the
backwards-incompatible Google Storage Access Frameworks.
Apps must have a new "read privileged phone state" permission in order to read non-resettable device identifiers, such as
IMEI number.

s, including app continuity when changing modes, changes to multi-window mode to allow all apps to run simultaneously (rather than only the actively-used app running, and all others being considered "paused"), and additional support for multiple displays.
"Direct Share" has been succeeded by "sharing shortcuts". As before, it allows apps to return lists of direct targets for sharing (such as a combination of an app and a specific contact) for use within share menus. Unlike Direct Share, apps publish their targets in advance and do not have to be polled at runtime, improving performance.
