Recommendation: Upgrade devices to the 8.1 build of Google’s mobile platform when available – it contains the latest fixes, final API updates for the 8.

Public rollout began August 21, 2017 (API level 26); the maintenance update arrived December 5, 2017 (API level 27). Key capabilities introduced with the 8.x releases include notification channels, picture-in-picture, autofill framework, adaptive icons, background execution limits, Project Treble for faster vendor updates, Wi‑Fi Aware (NAN), Vulkan 1.0 support and improved battery management.
For app developers: set compileSdk and targetSdk to API 27 where possible, migrate notifications to channels, replace long-running background services with JobScheduler/WorkManager, implement the autofill API for credentials, add support for adaptive icons, and run compatibility tests on devices and emulators at API 26 and 27 to catch behavior changes such as stricter background limits and new permission behaviors.
For device owners and IT admins: prefer manufacturer builds that include monthly security updates; choose devices with Project Treble support to improve upgrade prospects; if vendor updates stop, evaluate community-supported builds or plan hardware refresh to maintain security and access to modern APIs.
Quick Identification of Oreo on Your Device
Open Settings → About phone → Software information and confirm the OS entry shows API level 26 or 27, or a build string that begins with the letter “O”.
If the About screen lacks API info: tap Build number seven times to enable Developer options, then reopen About or Developer options and read the Build number; Oreo-era releases commonly use build prefixes like OPR or OPM (the leading “O” indicates the 8.x family).
Fast visual checks: look for notification dots on app icons, built-in picture-in-picture behavior when a video app is sent to the home screen, and adaptive icon shapes on the launcher. Try selecting text inside a message: smart text selection should show contextual actions (call, map, copy) in a small floating toolbar.
Notification changes: long-press an active notification to reveal channel controls or tap the gear/Details button to open notification categories. Swipe a notification slightly and tap the clock icon to snooze it–these controls are characteristic of the 8.x release.
Autofill and app access: open Settings → System → Languages & input (or Search in Settings for “Autofill”) – presence of an Autofill service entry and a dedicated Picture-in-picture list under Apps & notifications → Special app access are strong indicators of the 8.x build.
Prefer a tool: install a system-info utility such as AIDA64 or CPU-Z and check the “OS / SDK level” field; a reported SDK of 26 or 27 confirms the 8.x family without relying on vendor labels.
Open Settings → About phone to check version
Open Settings → About phone and inspect the entries labeled “Software information”, “Build number”, “Security patch level” and “SDK” to get the exact release identifier and build string.
- Open Settings and tap About phone or About device. If you see a search icon, type “About”.
- Tap Software information (on some models it appears as Software info or About phone → Software). Look for fields named Release, Build number, or Baseband.
- If the release string is not visible, tap Build number seven times to enable Developer options; then check Settings → System → About phone again or use Developer options to reveal additional details.
- For an exact numeric identifier, find the SDK entry or the numeric part of the release string (example format: X.Y.Z or X.Y). The SDK is an integer that maps to a specific platform release.
- If the Settings UI omits these labels, open Settings → System → Advanced → System update; some vendors place full software info there.
- Use the device boot screen: many phones show the build string or release during startup or on the recovery screen.
- If you have a PC available, run: adb shell getprop ro.build.version.release (returns the release string)
- Also useful: adb shell getprop ro.build.version.sdk (returns SDK integer) and adb shell getprop ro.build.version.codename (returns codename if present).
- Compare the SDK integer and release string against a trusted mapping table to identify the specific platform release used on the handset.
If Settings reports only a codename or a non-numeric label, collect Build number and Security patch level and search those strings on the vendor support site to confirm the exact release applied to that device.
