1. Check your internet connection: Make sure you have a stable and fast internet connection. Slow or unstable connections can cause video quality to be reduced.
2. Update your Messenger app: Go to the Google Play Store or Apple App Store and check if there is an update available for your Messenger app. If yes, install the update.
3. Clear cache and data of the Messenger app: Go to your phone's settings, select "Apps" or "Application Manager", find the Messenger app, and tap on "Clear Cache" and "Clear Data". This will delete any temporary files that may be causing the problem.
4. Reinstall the Messenger app: Uninstall the Messenger app from your phone and then reinstall it from the Google Play Store or Apple App Store.
5. Check your phone's storage: Make sure you have enough storage space on your phone. If your phone is running low on storage, it may affect the video quality.
6. Check your phone's settings: Go to your phone's settings and check if there are any restrictions or limitations on video quality.
7. Contact Facebook support: If none of the above steps work, you can contact Facebook support for further assistance. They may be able to help you resolve the issue.
As for Messenger mod apps, I would not recommend using them as they may be îllégâl and could potentially harm your device or compromise your privacy and security.
