Android 8.0 Oreo: official release date, new features and how to update your smartphone

Android 8.0 Oreo has become one one of the most anticipated updates to the mobile operating system from Google. This release brought not only cosmetic changes to the interface, but also major improvements in performance, security and energy efficiency. Many users are still interested in: when exactly was it released Android 8, what devices support it and how can you update today, years after the official announcement.

In this article we will analyze in detail the chronology of the release Oreo, the key innovations that made this version revolutionary, as well as current installation methods on modern and outdated gadgets. We will pay special attention compatibility issues to nuances that are rarely discussed in standard reviews. If you are still using a device on Android 7 Nougat or lower, here you will find answers whether it is worth upgrading to the eighth version.

The official release date of Android 8.0 Oreo

Android 8.0 Oreo has been announced August 21, 2017 during a total solar eclipse in the USA - Google specifically chose this day for the presentation, linking it with the “eclipse” of previous versions of the system. However the first stable builds for end users became available only on August 25 2017when the update began to spread to devices Google Pixel and Nexus via OTA (over the air).

Interesting fact: the name Oreo was confirmed in advance, back in March 2017, when Google launched a promotion with cookies Oreo and hidden Easter eggs in the beta version of the system. This became a tradition - each new version of Android was named after dessert in alphabetical order (after Nougat the letter "O" should have come).

• 📅 March 21, 2017 - the release of the first development preview version for testers.
• 🔄 May–July 2017 —monthly beta updates with bug fixes.
• 📱 August 25, 2017 —official release for devices Pixel, Nexus 5X, Nexus 6P i Pixel C.
• 🌍 September–December 2017 —gradual distribution to devices from other manufacturers (Samsung, Huawei, Xiaomi etc.).

It is important to understand that the release date for a particular smartphone depended on the manufacturer’s policy. For example, Samsung Galaxy S8 received Oreo only in February 2018, and some budget models remained at Android 7. This is due to the need to adapt the firmware to hardware and proprietary shells (for example, One UI or MIUI).

Key innovations in Android 8.0

Android Oreo brought more than 60 new features, but we will highlight those that really changed the user experience. Google's main emphasis was on performance, security i optimization of work in the background - this was a response to criticism that previous versions worked slowly on weak devices.

• ⚡ Boot acceleration —thanks to kernel optimization, the system ran on 30–50% faster (according to Google).
• 🔄 Limit background processes —applications could no longer consume resources uncontrollably, which increased battery life.
• 📦 Android Go —lite version for devices with 1 GB of RAM or less (came out later, but was based on architecture Oreo).

2. Security and privacy

• 🔒 Project Treble - revolutionary separation of system software and manufacturer drivers, which simplified updates.
• 🛡️ Google Play Protect - built-in antivirus that scans applications in real time.
• 📱 Restriction of installation from unknown sources - now permission must be given for everyone APK separately.

3. Interface and convenience

• 🎨 Adaptive icons —support for dynamic icons that change shape depending on the launcher.
• 📱 Picture-in-Picture (PiP) —the ability to view videos in a small window on top of other applications.
• 🔊 Notifications with channels —users got control over which notifications to show and which to block.
• 🖱️ Mouse and keyboard support —improved work with peripheral devices (relevant for Android TV i tablets).
