WhatsApp for Poco X7 Pro

HyperOS can block WhatsApp from writing to shared storage until you grant access. Open Settings > Apps > Manage apps > WhatsApp > Permissions and set Photos and videos (Files and media) to Allow. Then inside WhatsApp open Settings > Chats and turn on Media visibility so saved images are exposed to the Gallery, and check Settings > Storage and data > Media auto-download so incoming images actually download. After that, reboot once so the Gallery re-scans the WhatsApp Images folder. See how others solved this on Reddit

The Gallery indexes the WhatsApp media folder, so after an update or a permission reset the images can disappear from view. First confirm WhatsApp's Photos and videos (Files and media) permission is set to Allow under Settings > Apps > Manage apps > WhatsApp > Permissions. Then in the Gallery app check Albums to make sure WhatsApp isn't hidden. If it still won't show, clear only the Gallery cache via Settings > Apps > Manage apps > Gallery > Clear data > Clear cache and reboot to force a re-scan. See how others solved this on Reddit

HyperOS aggressive battery management is usually the cause. Go to Settings > Apps > Manage apps > WhatsApp, set Battery saver to No restrictions, and turn on Autostart. Then open Settings > Notifications & Control center > App notifications > WhatsApp and make sure notifications and Lock screen notifications are enabled. Inside WhatsApp, check Settings > Notifications and enable High priority notifications so alerts appear on the lock screen. See how others solved this on Reddit

Delayed notifications almost always come from background restrictions cutting WhatsApp's connection. In Settings > Apps > Manage apps > WhatsApp set Battery saver to No restrictions and turn on Autostart. Then go to Settings > Battery and turn off any battery-saver or ultra power-saving mode, which throttles background data so messages only arrive when you open the app. Keeping WhatsApp exempt from optimization lets it hold a steady background connection.

Start by clearing only the cache: Settings > Apps > Manage apps > WhatsApp > Clear data > Clear cache (this leaves your chats intact - do not tap Clear all data). Then update WhatsApp from the Play Store, since crashes often follow an outdated build on a new HyperOS version. If it still crashes on launch, uninstall and reinstall WhatsApp and restore from your Google Drive or local backup during setup. Make sure you're on the official Play Store version, not a modified APK, which frequently crashes on newer Android. See how others solved this on Reddit

WhatsApp rolls features out gradually by account and region, and the rollout isn't tied to your phone's brand, so HyperOS itself doesn't delay them. Make sure WhatsApp is fully updated in the Play Store (Play Store > profile icon > Manage apps & device). You can try the beta program from WhatsApp's Play Store page to get features earlier, but there's no device setting to force them - it's purely a server-side staged release.
