Verdict: Android 17’s Partial Screen Sharing allows you to cast, stream, or screen-record a single chosen application while incoming WhatsApp messages, SMS verification OTPs, and banking banners remain 100% invisible to viewers.
Sharing your smartphone screen during a work Zoom call, Discord livestream, or recording a video tutorial used to be a privacy minefield. A single untimely notification popup could broadcast sensitive personal text messages, 2FA authentication codes, or medical alerts to everyone watching.
Android 17 completely solves this by introducing app-isolated graphical window streaming. Follow this guide to enable and master Partial Screen Sharing.
How Partial Screen Sharing Works
Instead of capturing the entire OS display buffer (which includes the status bar, navigation rail, and notification shade), Android 17 hooks directly into the **single app window layer**:
– When you switch away from the shared app to check a text message, the viewer sees a clean paused screen with your chosen app’s icon.
– Incoming heads-up notification banners do **not appear** in the video stream.
– The top status bar (battery, carrier, time) is omitted from screen recordings.
Step-by-Step Guide: Sharing a Single App
1. Swipe down twice from the top of your screen to open the **Quick Settings** panel.
2. Tap the Screen Record or Screen Cast / Smart View tile.
3. In the setup popup dialog, select “A single app” instead of “Entire screen”.
4. A carousel of your running apps will appear. Tap the specific application you want to share (e.g., Google Slides, Discord, or Chrome).
5. Tap Start Recording / Start Casting.
What Happens When You Exit the App?
If you press the Home button or switch to another app during the broadcast:
– Android 17 **freezes the video feed** on the last frame of the shared application.
– Your private home screen icons, background wallpaper, and confidential apps are completely hidden from the audience.
– Once you reopen the shared app, streaming resumes automatically.
