WhatsApp Screen Sharing: How to Use It
WhatsApp’s screen sharing feature lets you broadcast your phone’s screen live during a video call, so the other participants see exactly what you see. You can start it from an ongoing call on Android or iPhone, and it works for both one-on-one and group calls. This article explains how to use it, what limits apply, and answers common questions.
What Is WhatsApp Screen Sharing?
Screen sharing is a built-in tool in WhatsApp’s video calling interface. When active, your camera feed is replaced by a live view of your phone’s display. The person on the other end sees everything you do on screen—apps, photos, messages, or a presentation—while your audio continues through the call. It’s handy for showing a document, helping someone troubleshoot a setting, or walking a friend through an app.
WhatsApp introduced the feature in 2023 for both Android and iOS. It works on the standard WhatsApp app; there is no separate download or plugin. The feature is free and uses the same data connection as your video call.
How to Start Screen Sharing on Android
On an Android phone (WhatsApp version 2.23.20 or later), the steps are:
- Start or join a video call in WhatsApp.
- Tap the screen share icon in the bottom toolbar—it looks like a rectangle with a person inside.
- If prompted, select “Start now� to allow WhatsApp to capture your screen.
- Your camera turns off, and your screen becomes visible to call participants.
- To stop, tap the red “Stop sharing� bar at the top of your screen.
On some Android versions, you may need to grant a “Screen overlay� or “Display over other apps� permission the first time. If the icon is missing, check for a WhatsApp update in the Play Store.
How to Start Screen Sharing on iPhone (iOS)
On an iPhone (iOS 12 or later, WhatsApp version 2.23.20 or later):
- Open a video call in WhatsApp.
- Tap the screen share icon (person inside a rectangle) in the call controls.
- Tap “Start Broadcast� when the system prompt appears.
- Your screen is now shared; your camera is disabled.
- Tap the red “Stop� button or the “Stop Sharing� option to end.
iOS will show a countdown before sharing begins. You can switch between camera and screen share anytime by tapping the same icon again.
What You Can and Cannot Share
Screen sharing broadcasts your entire screen, not just a single app. That means any notification, incoming message, or sensitive data that appears on your display will be visible to call participants. WhatsApp does not offer a “share a specific window� option like desktop apps do.
You can share:
- Photos and videos in your gallery
- Web pages in a browser
- Documents and PDFs
- Settings menus or apps you’re troubleshooting
- Games or other full-screen apps
You cannot share:
- DRM-protected content (like Netflix or Disney+ movies) – the screen will appear black to others
- Your screen while using the camera simultaneously – sharing replaces the camera feed
- Individual files as a “presentation� – you simply show whatever is on screen
Common Problems and How to Fix Them
If screen sharing doesn’t work, try these fixes:
- No icon visible: Update WhatsApp to the latest version from your app store. The feature requires a recent version.
- Black screen on the receiver’s side: This happens with DRM-protected apps (streaming services). Close the app and share something else.
- Screen share stops suddenly: Check your internet connection. A weak signal can interrupt the broadcast. Also, if you lock your phone, sharing will pause.
- No audio when sharing: Screen sharing uses the call’s microphone. Make sure you haven’t muted the call. If you’re sharing a video with sound, the other person may hear it through your microphone, not as direct audio.
- Permission errors on Android: Go to Settings > Apps > WhatsApp > Permissions and enable “Screen overlay� or “Display over other apps.�
Privacy and Safety Tips
Because screen sharing exposes everything on your display, take precautions:
- Close private chats, emails, or banking apps before sharing.
- Turn off notifications or use “Do Not Disturb� mode so incoming messages don’t pop up.
- Only share with people you trust—anything you show can be recorded by the other party.
- Remember that screen sharing does not record the call; it’s live only. But participants can take screenshots or use another device to record.
- Stop sharing immediately if you need to open a sensitive app.
Screen Sharing vs. Other Methods
WhatsApp’s screen sharing is simple and built-in, but it has limitations compared to dedicated tools:
- Zoom/Google Meet: Allow sharing a single window or a specific app, which is more private. They also let you share a whiteboard or give control to another user.
- TeamViewer/AnyDesk: Provide remote control, not just viewing. WhatsApp only shows your screen; the other person cannot interact with it.
- YouTube Live or Twitch: Are for public streaming, not private calls.
For quick, personal help, WhatsApp is the easiest because the other person is already on the call. For professional presentations or collaborative work, a dedicated tool offers more control.
Frequently Asked Questions
Does screen sharing work on WhatsApp Web or desktop?
No. As of now, screen sharing is only available on the mobile apps (Android and iOS). WhatsApp Web and the desktop app do not have a screen share button in video calls.
Can I share my screen during a voice call?
No. Screen sharing requires a video call. If you’re on a voice call, you need to switch to a video call first (tap the video icon) and then start screen sharing.
Does the other person hear audio from my phone when I share a video?
Not directly. The screen share only transmits video. The other person will hear whatever your microphone picks up, including the audio from your phone’s speakers. For better sound, you can play the video at a moderate volume or use headphones.
Is screen sharing end-to-end encrypted?
Yes. WhatsApp calls, including screen sharing, are protected by end-to-end encryption. That means only the participants in the call can see the shared content—WhatsApp itself cannot view it.
Can I use screen sharing in a group call?
Yes. Screen sharing works in group video calls. All participants will see your screen. Only one person can share at a time; if you start sharing while someone else is sharing, it will switch to you.
Why is my screen sharing blacked out?
The most common reason is DRM-protected content (like Netflix, Hulu, or other streaming apps). These apps block screen capture for copyright reasons. Also, some banking apps and secure browsers may block screen sharing. Close the app and share something else.
