How to Fix Telegram Video Call Screen Sharing Not Working?

In remote work, online teaching, and interactions with friends and relatives, Telegram's video call screen sharing feature has become a core need—whether sharing work documents, demonstrating operation steps, or browsing content synchronously, this function can improve communication efficiency. However, many users encounter issues such as "screen sharing fails to start," "the other party cannot see the shared screen," and "crash after sharing" when using it, especially on different devices like Android, iOS, Windows, and macOS. This article will provide step-by-step troubleshooting solutions for common Telegram screen sharing failures, while addressing high-frequency related questions from Google and Bing searches (e.g., "Telegram screen share not working 2024," "Telegram group video call screen sharing failed"), helping you quickly restore the function.

I. First, Clarify: Basic Requirements for Telegram Screen Sharing

Before troubleshooting, confirm that your device and operations meet Telegram's functional requirements to avoid ineffective attempts:

1. Device and Version Support: Telegram screen sharing is only available for Android 8.0+, iOS 12.0+, Windows 10/11, macOS 10.14+, and the latest version of the Telegram app (mobile version 4.0+ and desktop version 4.0.0+). Older devices or outdated apps may lack this feature entirely.
2. Call Type Restrictions: Both one-on-one video calls and group video calls support screen sharing, but group calls must be initiated by an administrator. Additionally, some older app versions only allow up to 10 participants to join the sharing.
3. Basic Operation Process: The correct steps are "Initiate a video call → Click the screen sharing icon after connecting → Select the sharing scope (full screen/specific app) → Confirm sharing." Attempting to share directly without "connecting the call" or failing to select a sharing target will cause the function to fail.

II. Device-Specific Troubleshooting: Common Issues and Solutions for Telegram Screen Sharing

(1) Android Devices: Permissions and Background Conflicts Are the Main Causes

80% of screen sharing issues on Android devices stem from unenabled permissions or background app interference. Follow these specific solutions:

1. Enable Core Permissions: Telegram screen sharing requires "Screen Recording," "Floating Window," and "Media Access" permissions. Operation path: Settings → Apps → Telegram → Permissions, ensure "Screen Recording," "Floating Window," and "Storage" are all enabled. Some models require additional authorization for Telegram to use the feature in "Settings → System → Advanced → Screen Recording."
2. Disable Data Saver Mode: Enabling "Data Saver" will restrict Telegram's bandwidth usage, leading to lag or failure to start screen sharing. Disable path: Telegram → Settings → Data and Storage → Turn off "Data Saver for Video Calls," and grant Telegram the "Unrestricted Data Usage" permission in the phone's system settings.
3. Close Conflicting Background Apps: Screen recording tools, live streaming software, security guards, etc., may occupy screen recording resources, preventing Telegram from accessing them. Long-press the multitasking button to close all non-essential background apps, especially other screen-sharing-supported apps (e.g., Zoom, Google Meet).
4. Update or Reinstall the App: Check for Telegram updates in the Google Play Store. If the issue persists with the latest version, uninstall and reinstall the app (back up chat history first). Some users report that Android 13+ models require separate authorization for Telegram in "Settings → Privacy → Permission Management → Special Permissions → Screen Recording."

(2) iOS Devices: Screen Recording and System Settings Need Synchronous Configuration

Due to iOS's closed ecosystem, screen sharing issues are mostly related to system-level settings. Focus on the following checks:

1. Add Screen Recording to Control Center: iOS requires the Screen Recording feature to be added to the Control Center first for Telegram to access it. Operation: Settings → Control Center → Customize Controls, tap the "+" icon next to "Screen Recording." When sharing, start Screen Recording from the Control Center first, then select "Share Screen" in Telegram.
2. Allow Telegram to Access Screen Recording: Go to Settings → Privacy & Security → Screen Recording, ensure the Telegram toggle is enabled. If Telegram is not listed, initiate a screen sharing attempt first— the system will pop up a permission request window, tap "Allow."
3. Disable Focus Mode (Do Not Disturb): Focus Mode restricts background app activities, which may cause screen sharing to interrupt. Swipe down from the top-right corner to open Control Center, tap the Focus Mode icon (Moon/Do Not Disturb) to disable it.
4. Check System and App Compatibility: iOS versions below 12 do not support Telegram screen sharing—update the system (Settings → General → Software Update). Ensure Telegram is the latest version from the App Store; some users report that iPhone 15 series require iOS 17.2+ for stable use of this feature.

(3) Windows Desktop: Version Bugs and Driver Issues Are Prominent

Windows users commonly encounter issues like "first-time sharing failure" and "crash after sharing." Based on BUG feedback from GitHub users, here are the solutions:

1. Retry Sharing (Temporary BUG Fix): Some Windows 10 21H2/11 22H2 users report that the first click on "Screen Sharing" fails. Return to the call interface, tap "Stop Sharing," and initiate sharing again—this is a known BUG in Telegram 4.0.0, and there is no official fix yet. Retrying is a temporarily effective solution.
2. Enable Screen Recording Permissions: Windows 10/11 requires authorization in system settings: Settings → Privacy & Security → Screen Recording, find Telegram and enable the permission. If Telegram is not listed, uninstall it and reinstall via the Microsoft Store (ensure the installation source is official).
3. Update Graphics Card Drivers: Outdated graphics card drivers cause screen rendering abnormalities, preventing normal sharing. Right-click "This PC" → Manage → Device Manager → Display Adapters, right-click to update the graphics card driver (NVIDIA/AMD users can update via official tools). If the driver is up-to-date but the issue persists, try disabling GPU hardware acceleration (Telegram → Settings → Advanced → Turn off "Hardware Acceleration").
4. Disable Security Software Interception: 360 Security Guard, Huorong, etc., may mistakenly flag Telegram screen sharing as a "screen capture risk." Temporarily disable real-time protection or add Telegram to the whitelist. Check Windows Firewall to ensure Telegram is allowed access through public and private networks.

(4) macOS Desktop: Permission Gaps and System Compatibility Issues

macOS users mainly face issues like "no permission to access camera/screen" and "incompatibility with old systems." Follow these steps:

1. Complete Privacy Permissions: Go to System Settings → Privacy & Security → Screen Recording, check Telegram; ensure Telegram is authorized in "Camera" and "Microphone" options. Some macOS Monterey/Big Sur users report that the system does not automatically generate a camera permission entry for Telegram—reinstall Telegram and restart the computer to resolve this.
2. Update System to Supported Version: macOS versions below 10.14 (Mojave) do not support Telegram screen sharing—update the system (System Settings → General → Software Update). Older Macs (e.g., MacBook Air A1466 from 2013 or earlier) may experience lag during sharing due to insufficient hardware performance even after updating to the latest supported system. It is recommended to replace the device or use a Windows dual system.
3. Close Other Camera-Occupying Apps: Mac's camera and screen recording resources can only be used by one app at a time. Close Photo Booth, FaceTime, and other video conferencing software (e.g., Teams) to ensure Telegram exclusively uses the device's resources.

III. Universal Troubleshooting: Core Tips for All Devices

If the above device-specific solutions do not resolve the issue, try these universal methods covering network, account, server, and other underlying problems:

1. Check Network Stability: Screen sharing requires high bandwidth (upload speed ≥ 2Mbps is recommended). Prioritize using a wired network; Wi-Fi users should stay close to the router to avoid signal interference. Test the network with Speedtest—if packet loss is high or latency exceeds 100ms, restart the router or switch networks (e.g., mobile hotspot).
2. Log Out and Log Back In: Corrupted Telegram cache files may cause functional abnormalities. Logging out and back in can clear some cache errors. Mobile: Settings → Log Out; Desktop: Click the top-left menu → Log Out.
3. Confirm the Other Party's Device Support: If you can initiate sharing but the other party cannot see the screen, the other party's device may not have the latest Telegram version or may not support screen sharing (e.g., old phones, Telegram Web). Advise the other party to check their device and app version following the steps in this article.
4. Report BUG to Official Support: If all methods fail, it may be a Telegram version BUG (e.g., group sharing failure, specific model adaptation issues). Use Telegram's built-in feedback channel: Settings → Help → Contact Us, and describe the device model, system version, and issue in detail. The official team will fix it in subsequent updates.
