WhatsApp for Honor Magic Vs

Honor's aggressive battery optimization in MagicOS closes WhatsApp in the background, which silently kills notification delivery over time. Go to Settings > Apps > Apps > WhatsApp > Battery usage (or App launch) and set WhatsApp to "No restrictions", then open Settings > Apps > Launch, switch WhatsApp to "Manage manually" and enable auto-launch, secondary launch and run in background. Also confirm notifications are allowed for WhatsApp under Settings > Notifications and that any battery saver mode is off. See how others solved this on Reddit

This usually happens when WhatsApp can't display over other apps or pop up from the background on MagicOS. Open Settings > Apps > Apps > WhatsApp > Permissions and enable "Display over other apps" and "Display pop-up windows while running in the background", then set the same app's battery usage to "No restrictions" so it isn't killed in standby. Inside WhatsApp, go to Settings > Notifications and keep "Use high-priority notifications" turned on so the full-screen call alert appears. See how others solved this on Reddit

A black, frozen or laggy in-app camera is usually a permissions or cache problem rather than hardware. Open Settings > Apps > Apps > WhatsApp > Permissions and make sure Camera and Microphone are set to "Allow", then clear the app cache via Settings > Apps > Apps > WhatsApp > Storage > Clear cache and reboot. If it stays choppy, use the system camera instead (take the photo or video in the Camera app, then attach it from the gallery in WhatsApp) and make sure WhatsApp is updated from the Google Play Store.

Distorted voice recordings are usually caused by a covered microphone or noise-suppression processing interfering with the recording. Check that nothing (case, finger, or screen-protector film) is blocking the mic holes, then grant the mic full access under Settings > Apps > Apps > WhatsApp > Permissions > Microphone. If it persists, clear WhatsApp's cache and update the app from the Play Store, since several recording-quality bugs have been fixed in newer WhatsApp builds. See how others solved this on Reddit

Failed video sends are most often caused by an unstable connection or a corrupted upload cache rather than the file itself, since modern WhatsApp supports videos up to 2GB. First confirm you have a stable Wi-Fi or mobile-data connection, then clear cache under Settings > Apps > Apps > WhatsApp > Storage > Clear cache and make sure Storage/Media permission is granted under Permissions. If a specific clip still fails, send it as a Document to bypass re-encoding, or trim it and retry. See how others solved this on Reddit

Because the Magic Vs runs Android, the cleanest method is a Google Drive backup: on your old phone open WhatsApp > Settings > Chats > Chat backup, link a Google account and back up, then sign in with the same account and phone number on the Magic Vs and restore when prompted during WhatsApp setup. If your old phone was an iPhone, use WhatsApp's official "Move to Android" tool by connecting both devices with a cable and scanning the on-screen QR code, since iCloud backups can't be restored directly on Android.
