Introduction
If you bought a Pixel in 2020, you did it during a pandemic, during a US presidential election, during a year when Google’s hardware ambitions looked shakier than ever. The Pixel 5 wasn’t a flagship — it was a mid-range phone with a flagship price that Google positioned as “what matters, at a price that makes sense.” Android 11 had to carry that narrative, and surprisingly, it did.
Android 11 was officially released on September 8, 2020.
Android 11 was a communication-focused release. Conversations got their own notification section. Bubbles brought Facebook Messenger-style floating chat heads to any messaging app. The power menu became a smart home control center. Screen recording went native. And one-time permissions let you grant camera, microphone, and location access for a single session — the privacy feature everyone should have had years earlier.
Android 11 didn’t redesign Android. It refined it, focusing on how people actually use their phones: messaging friends, controlling smart homes, and managing privacy.

What’s New
Conversations Section in Notifications
Android 11 created a dedicated “Conversations” section at the top of the notification shade, separate from “Alerting” and “Silent” notifications. Messaging apps — SMS, WhatsApp, Telegram, Messenger — appeared in this section with priority placement, larger contact avatars, and dedicated actions.
The Conversations section was a recognition that messaging is the primary use case for most smartphone users, and notifications from people should be treated differently from notifications from apps. It also supported “Bubbles” — floating chat heads — and conversation-specific priority settings.
This was subtle but impactful. Conversations from actual humans no longer got buried under promotional emails and app alerts. For anyone who uses their phone primarily to communicate, this was the most meaningful notification change since Nougat’s bundled notifications.
Bubbles
Bubbles were Android’s native implementation of floating chat heads, popularized by Facebook Messenger. Tapping a conversation notification could open it as a floating bubble — a circular contact icon that hovered over other apps. Tapping the bubble opened the conversation in a floating window.
Bubbles were optional (developers had to implement the API, and users could disable them per-conversation). They were useful for ongoing conversations while multitasking — texting while browsing, responding to WhatsApp while watching YouTube — and they worked across all messaging apps that adopted the API.
Adoption was spotty. Some apps embraced Bubbles immediately (Telegram, Google Messages). Others (WhatsApp, Instagram) took years. Facebook Messenger continued using its own bubble implementation rather than adopting Android’s native API. Bubbles never became universal, but the API was solid and the UX was good.
One-Time Permissions
Android 11 added “Only this time” as a permission option for camera, microphone, and location. Grant a permission for a single session, and it auto-revoked when the app was closed (or after a short timeout for background access).
This was the middle ground between “Deny” and “Allow all the time” that users needed. Want to send a photo via Instagram? Grant camera access for that session only. Using a ride-share app? Grant location for that ride, not forever.
One-time permissions were popular: Google reported that 65% of users chose “Only this time” for location and camera permissions when offered. The feature reduced persistent background access and gave users more granular control.
Built-In Screen Recorder
Android 11 added a native screen recorder — no third-party app or ADB command required. Record with audio (device, microphone, or both), show touches on screen, and save to the camera roll. The recorder appeared as a Quick Settings tile.
Screen recording had been available through third-party apps for years, and Samsung/OEMs had included it in skins, but native implementation meant better performance, lower battery drain, and consistent behavior across devices.
Smart Device Controls (Power Menu)
Long-pressing the power button in Android 11 didn’t just show power options — it showed a smart home control dashboard. Lights, thermostats, locks, cameras, and other Google Home-compatible devices appeared as large, tappable tiles. Adjust brightness, toggle lights, view camera feeds, all without opening the Google Home app.
This was brilliant. The power button is the most physically accessible button on any phone, and mapping it to smart home controls made those controls genuinely convenient. The downside: it replaced the screenshot shortcut (Power + Volume Down still worked, but the power menu changed), and some users found the home controls cluttered.
Android 12 moved these controls to the lock screen and notification shade, which was a better location. But Android 11’s power-menu smart home was a clever experiment.
User Interface Changes
- Media controls in Quick Settings: Playback controls moved from the notification shade to the Quick Settings panel, with larger album art and dedicated playback controls. Swipe down to see what’s playing and control it directly.
- Notification history: Android 11 kept a 24-hour history of dismissed notifications, accessible via Settings → Notifications → Notification history. Accidentally swiped away an important alert? It was recoverable.
- Pin apps in share sheet: The Android share sheet — historically slow and unpredictable — got pinning. Pin your most-used sharing targets (specific contacts, apps) to the top, and they stayed there.
- Dark theme scheduling: Dark theme could follow sunrise/sunset automatically, matching the user’s location.
Performance Improvements
- Incremental file system: Android 11 added support for Incremental File System, allowing large apps (games, AR experiences) to be played before fully downloaded. The system loaded only the data needed for the current stage, streaming the rest on demand.
- Low-latency video decoding: Reduced video decoding latency for game streaming (Stadia, GeForce Now) and real-time applications.
Security Improvements
- One-time permissions: Camera, mic, and location — grant once, auto-revoke.
- Auto-reset permissions: Permissions for apps not used in several months were automatically revoked. The app could request them again on next launch, but background access was cut after extended inactivity.
- Background location access: Apps requesting background location had to go through a separate, explicit permission flow (not bundled with foreground location).
- Scoped Storage enforcement: Apps targeting API 30 were required to use Scoped Storage (no opt-out).
- BiometricPrompt security levels: Apps could specify required biometric security strength — Class 3 (Strong) required hardware-backed biometrics (fingerprint, iris, 3D face); Class 2 (Weak) was acceptable for convenience authentication; Class 1 (Convenience) was minimal.

Android 11 refined Android 10’s foundation. Conversations and Bubbles made messaging central to the OS. One-time permissions closed a privacy gap. Screen recording and notification history added utility. Nothing revolutionary, but dozens of thoughtful improvements.
Legacy and Impact
One-time permissions became the standard Android permission model. Google extended the concept in Android 12 with approximate location, and in 13 with more granular media permissions. The idea — grant temporarily, not permanently — is now core to Android’s privacy architecture.
Conversations and Bubbles established messaging as a first-class OS function. Apple followed with “Focus” modes in iOS 15 that similarly prioritized communications. The trend toward treating messages from people as fundamentally different from app notifications is now industry standard.
The Pixel 5, while commercially modest, established Google’s “premium mid-range” strategy that continues with the Pixel A-series and Pixel 8a. Not every Pixel needs to compete with the Galaxy Ultra. Android 11 ran beautifully on the Snapdragon 765G, proving that optimization matters more than raw specs.
End of Support
- Play Services: Fully supported (API 30+).
- Project Mainline: Android 11’s modular components continue receiving updates, extending practical support beyond OEM security patches.
Fun Facts
- Internal codename: Android 11 was internally “Red Velvet Cake” (RVC). AOSP commits and Google’s internal documentation referenced RVC throughout development. The public-facing name was simply “Android 11.”
- Easter egg: The Android 11 easter egg was a dial, with three settings: “Cat Controls,” “Water,” and “Power.” Turning the dial to “Cat Controls” activated the Android Neko cat-collector game (carried over from Nougat). Turning to “Water” showed a bubble animation. The dial itself was a reference to Android’s evolution.
- Pixel 5 screen gap: Some Pixel 5 units had a visible gap between the display panel and the aluminum body. Google claimed it was “normal” and within design tolerances. Users disagreed. The gap didn’t affect water resistance but looked sloppy.
- Covid-19 Exposure Notifications: Android 11 integrated the Exposure Notifications System (developed jointly with Apple) at the OS level, enabling COVID-19 contact tracing apps without requiring location permission.
Frequently Asked Questions
What API level is Android 11?
API Level 30.
What are Bubbles?
Bubbles are floating chat heads that overlay on top of other apps, enabling ongoing conversations while multitasking. They can be enabled per-conversation and are supported by messaging apps that implement the Bubbles API.
How do one-time permissions work?
When an app requests camera, microphone, or location access, users can choose “Only this time” in addition to “While using the app” and “Deny.” The permission auto-revokes when the app is closed.
Did the Pixel 5 have flagship specs?
No. The Snapdragon 765G was a mid-range processor. Google argued that Android 11’s optimization made premium specs unnecessary for the Pixel experience. Reviews were mixed — performance was fine for daily use but notably slower than Snapdragon 865/888 phones in gaming and heavy multitasking.
Final Thoughts
Android 11 wasn’t ambitious. It didn’t redesign the UI, revolutionize multitasking, or introduce a transformative new feature category. What it did was make Android better at the things people actually use their phones for: talking to people, controlling their homes, and managing their privacy.
The Conversations section recognized that messaging is the smartphone’s killer app. Bubbles made multitasking while chatting practical. One-time permissions finally gave users granular privacy control. The screen recorder was overdue. The smart home controls in the power menu were clever, even if they didn’t survive to Android 12.
Android 11 was a maintenance release in the best sense — it maintained what worked and refined what didn’t. It ran well on modest hardware (Pixel 5, 4a), it didn’t break anything, and it made Android better without making it louder. In a year defined by chaos, Android 11 was quietly, reliably good.
