WhatsApp for Honor Magic 7 Pro

MagicOS aggressively manages background apps, which can starve WhatsApp's in-app camera and make the live preview stutter. Go to Settings > Apps > Apps > WhatsApp > App launch (or Launch), switch it from Auto to Manage manually, and enable Auto-launch, Secondary launch and Run in background. Then open Settings > Battery > App launch / battery usage and set WhatsApp so it is not restricted. If the in-app camera still stutters, shoot the photo or video in your phone's main Camera app first and attach it in the chat instead of using WhatsApp's built-in camera.

Honor and WhatsApp have shipped MagicOS and app updates that improve it, so first make sure both are current. Update WhatsApp from the Google Play Store (or the Honor App Market) and check Settings > System & updates > Software update for the latest MagicOS build. If the live preview is still laggy after updating, the reliable workaround remains capturing the media in the stock Camera app and sharing it into the chat rather than using WhatsApp's built-in camera.

Honor's noise-suppression and audio processing can over-filter the microphone during WhatsApp recordings, making voice notes sound thin or compressed. Make sure a case or screen protector is not covering the bottom microphone, and confirm WhatsApp has the Microphone permission under Settings > Apps > Apps > WhatsApp > Permissions. Recording in a quiet room and holding the phone with the bottom mic pointed toward your mouth (not muffled against your hand) gives the cleanest result; if it persists, check for a WhatsApp update, since several of these audio glitches were fixed in app updates.

MagicOS closes WhatsApp in the background to save battery, which stops push notifications from arriving. Open Settings > Apps > Apps > WhatsApp > App launch, set it to Manage manually and turn on all three options (Auto-launch, Secondary launch, Run in background), then set WhatsApp to unrestricted in Settings > Battery. Finally, in WhatsApp go to Settings > Notifications and make sure message and group notifications are enabled, and confirm WhatsApp notifications are allowed under Settings > Notifications & status bar.

Calls fail to ring or pop up when WhatsApp loses its background and full-screen permissions under MagicOS. Grant WhatsApp the Display over other apps (pop-up windows) permission under Settings > Apps > Apps > WhatsApp, make sure Calls notifications are enabled in WhatsApp > Settings > Notifications, and set WhatsApp to unrestricted in Settings > Battery so it can run in the background. Locking WhatsApp in the Recents screen (open Recents, hold the WhatsApp card and tap the lock icon) also stops the system from killing it between calls. See how others solved this on Reddit
