Screen sharing on mobile Facebook Messenger is only possible during an active video or audio call and relies on your device’s built-in screen recording feature. 2. On iPhone, start a call, open Control Center, tap Screen Recording, wait for the countdown, then select “Share Screen” or “Broadcast to Messenger” from the red status bar. 3. On Android, during a call, swipe down the notification panel, tap “Screen Share” or “Cast,” choose “Messenger,” and tap Start Now to begin sharing. 4. Some Android devices like Samsung phones may have proprietary screen recorders with app-specific broadcast options. 5. Limitations include no standalone screen sharing outside calls, lack of support on older devices, potential absence of microphone audio, and increased battery and data usage. 6. For best results, close unnecessary apps, use Wi-Fi, test with a friend first, and use headphones to prevent echo. While Messenger lacks a native screen share button, this method enables screen sharing when your device supports it.

Screen sharing isn’t directly supported in the standard mobile version of Facebook Messenger — at least not in the way you might expect, like sharing your entire screen during a chat. However, there is a workaround if you're on a video or audio call, and it works differently depending on your device (iOS or Android). Here’s how to do it and what to expect.

? How to Share Your Screen on Messenger Mobile (During a Call)

Messenger allows screen sharing only during an active video or audio call, and it's currently supported on both iOS and Android — but you need to use the built-in screen sharing feature from your phone's operating system.

On iPhone (iOS):

1. Start a video or audio call in Messenger.
2. Once the call is active, swipe down from the top-right corner (iPhone X or later) to open the Control Center.
3. Tap Screen Recording (the circle-within-a-circle icon).
4. Wait 3 seconds for the countdown, then your screen will start recording.
5. Tap the red status bar at the top of your screen.
6. Choose "Share Screen" or "Broadcast to Messenger" (if available).
7. Your screen will now be shared with the person you're calling.

? Note: This feature may not appear for all users yet — it depends on your iOS version and whether Meta has rolled out the integration fully.

On Android:

1. Start a video or audio call in Messenger.
2. Swipe down the notification panel and tap "Screen Share" or "Cast" (exact wording varies by device).
3. Select "Messenger" or "Share to Messenger call" when prompted.
4. Tap Start Now to begin sharing your screen.
5. The other person will now see your screen in real time.

? Some Android phones (like Samsung) have their own screen recorder with app-specific sharing options. Look for a "Share" or "Broadcast" option during screen recording.

?? Important Limitations

• No standalone screen share: You can’t share your screen outside of an active call.
• Not all devices support it: Older phones or certain Android models may not show the screen share option.
• Audio may be limited: Only system audio is shared on some devices; microphone audio might be turned off automatically.
• Battery and data usage: Screen sharing uses more battery and data, especially in HD.

Tips for Better Screen Sharing

• Close unnecessary apps before starting to avoid accidental exposure.
• Make sure you're on Wi-Fi to prevent data overages.
• Test it with a friend first to ensure it works on your device.
• Use headphones to avoid echo during the call.

Basically, Messenger doesn’t have its own screen share button like Zoom or Teams — it relies on your phone’s native screen recording and broadcasting features. So while it’s not as straightforward, it is possible if your device supports it.
