WhatsApp for Honor

This is usually a permissions or cache issue with MagicOS. Go to Settings > Apps > Apps > WhatsApp > Permissions and make sure Camera is set to Allow. Then go back to the WhatsApp app info screen, tap Storage, and clear the cache. If the in-app camera still freezes or shows a black screen, update WhatsApp from AppGallery or the Play Store and reboot the phone, then try again. See how others solved this on Reddit

WhatsApp's in-app camera runs at a lower frame rate than the stock Camera app, and MagicOS power management can throttle WhatsApp in the background, making it worse. Open Settings > Apps > Apps > WhatsApp > Battery and set it to "No restrictions" (and under App launch make sure WhatsApp is managed manually with Auto-launch and Run in background enabled). For the smoothest results, shoot with your stock Camera app and attach the photo from the gallery instead of using WhatsApp's built-in camera. See how others solved this on Reddit

MagicOS aggressively kills background apps, which stops WhatsApp from waking for calls. Go to Settings > Apps > WhatsApp > Battery and set it to 'No restrictions' (instead of automatic management), then enable 'Auto-launch', 'Secondary launch' and 'Run in background'. Also lock WhatsApp in the Recents view by swiping down on its card and tapping the padlock so MagicOS stops clearing it from memory. See how others solved this on Reddit

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 rates the hinge for hundreds of thousands of fold cycles (owners report it holding up well past 350,000 opens), which is far more than typical daily use will ever reach, so normal folding will not wear it out. To keep it healthy, avoid forcing the phone open in very cold weather (let it warm up first) and never close it on grit or sand in your pocket, since debris is the main cause of hinge and inner-screen damage.

This is almost always MagicOS battery management suspending WhatsApp in the background. Open Settings > Apps > App launch, find WhatsApp, turn off "Manage automatically" and in the pop-up enable all three options (Auto-launch, Secondary launch, Run in background). Then go to Settings > Apps > Apps > WhatsApp > Notifications and make sure the Calls notification channel is enabled, and inside WhatsApp open Settings > Notifications and turn on "Use high priority notifications" / pop-on-screen. Finally, in Settings > Battery, turn off any aggressive power-saving mode for WhatsApp so call screens can appear when the phone is locked. See how others solved this on Reddit

MagicOS aggressively closes background apps to save battery, which is the main cause of missing or late WhatsApp alerts. Go to Settings > Apps > App launch (App launch management), find WhatsApp, turn off automatic management, then enable Auto-launch, Secondary launch and Run in background. Also open Settings > Battery, and make sure WhatsApp is not restricted by any power-saving optimization. See how others solved this on Reddit

This is almost always Honor's aggressive battery management (MagicOS) closing WhatsApp in the background. Go to Settings > Apps > Apps > WhatsApp > Battery and set it to "No restrictions". Then open Settings > Battery > Launch, find WhatsApp, switch it from "Manage automatically" to "Manage manually", and turn on all three toggles: Auto-launch, Secondary launch and Run in background. Finally, open Recents (swipe up and hold), find WhatsApp and tap the padlock icon to lock it so MagicOS stops killing it. After this, notifications arrive in real time.

MagicOS aggressively kills background apps, so go to Settings > Apps > WhatsApp > Battery (or App battery usage) and set it to "No restrictions" / "Unrestricted". Then open Settings > Battery > App launch, find WhatsApp, switch it from "Manage automatically" to "Manage manually", and enable Auto-launch, Secondary launch, and Run in background. Finally confirm notifications are allowed under Settings > Notifications > WhatsApp. See how others solved this on Reddit

MagicOS aggressively sleeps background apps, which delays or kills WhatsApp pushes. Go to Settings > Apps > App launch, find WhatsApp, switch it from Auto to Manage manually, then enable Auto-launch, Secondary launch, and Run in background. Also exclude WhatsApp from battery optimization: Settings > Battery > More battery settings > App launch, or Settings > Apps > WhatsApp > Battery usage > set to Don't optimize. This lets the app wake and post notifications instantly. See how others solved this on Reddit
