WhatsApp for Xiaomi 14T

HyperOS aggressively manages background apps to save battery, which can stop WhatsApp from waking up to deliver alerts. Open Settings > Apps > Manage apps > WhatsApp, set Battery saver to No restrictions, and turn on Autostart so it can run in the background. Then go to Settings > Notifications & Control Center > App notifications > WhatsApp and make sure all categories (Messages and Calls) are enabled with sound and pop-up (floating notifications) turned on.

This happens when HyperOS suspends WhatsApp's background service or blocks its full-screen call alert. In Settings > Apps > Manage apps > WhatsApp, enable Autostart and set Battery saver to No restrictions, then lock WhatsApp in Recents (open Recents, hold the app card, tap the lock icon) so it is not cleared from memory. Finally, in Settings > Notifications & Control Center > App notifications > WhatsApp > Calls, enable the category and turn on Floating notifications so incoming calls appear on screen.

Do Not Disturb on HyperOS silences WhatsApp unless you allow it as an exception. Go to Settings > Sound & vibration > Do Not Disturb > Apps and add WhatsApp so its alerts break through. Also confirm Battery saver is set to No restrictions for WhatsApp in Settings > Apps > Manage apps > WhatsApp, since a suspended app often only catches up on notifications when you wake the screen.

After recent Gallery updates the WhatsApp media folders may stop being indexed automatically even though the files still exist. Open the Files app and check Internal storage > Android > media > com.whatsapp > WhatsApp > Media to confirm the photos are there. To make them reappear, open WhatsApp > Settings > Chats and enable Media visibility, then reboot the phone so Gallery re-scans the folders. See how others solved this on Reddit

The blue Meta AI circle is a server-side WhatsApp feature, so it cannot be removed through HyperOS or Xiaomi 14T phone settings. Keep WhatsApp updated from the Play Store (or Mi GetApps), since any opt-out controls arrive through app updates. You can swipe the AI chat away or archive it, but there is currently no reliable in-app toggle to remove it entirely once Meta has enabled it in your region. See how others solved this on Reddit

HyperOS can block these apps from launching their full-screen call interface in the background, so the call never rings until you open the app. For each calling app go to Settings > Apps > Manage apps > [app] > Other permissions and enable "Display pop-up windows while running in the background" and "Start in background," then set Battery saver to No restrictions. Combine this with Autostart enabled and locking the app in Recents so HyperOS keeps its call service alive. See how others solved this on Reddit
