WhatsApp for Motorola Moto G Stylus 5G (2024)

Motorola's aggressive battery optimization is the usual culprit. Go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted, then open Settings > Battery > Battery optimization, find WhatsApp and choose Don't optimize. Also confirm Settings > Apps > WhatsApp > Notifications is on and that Message notifications has a sound assigned. See how others solved this on Reddit

Delayed or silent notifications that only land once you open WhatsApp point to the phone killing background data to save power. In Settings > Apps > WhatsApp > Mobile data & Wi-Fi, enable Background data and Unrestricted data usage, then disable Adaptive Battery under Settings > Battery. Locking WhatsApp in the Recents/multitasking view (tap the app icon at the top of its card and pick Lock) also stops the system from clearing it. See how others solved this on Reddit

This is often tied to a recent Android update conflicting with the camera and microphone permissions. Clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache, then re-grant Camera and Microphone under Settings > Apps > WhatsApp > Permissions. If calls still fail, make sure WhatsApp is on the latest version from the Play Store, since several call-stability bugs on the 2024 Moto firmware were patched in app updates.

Motorola groups and silently collapses notifications, so WhatsApp alerts can end up under a hidden or minimized section. Long-press a WhatsApp notification, tap the gear, and set its importance to Default or High so it stays visible and pops on screen. Also turn off Settings > Notifications > Enhanced notifications (the AI sorting feature), which is what shuffles items out of view. See how others solved this on Reddit

First check that Do Not Disturb isn't stuck on under Settings > Notifications > Do Not Disturb, and verify Settings > Notifications > App settings shows WhatsApp enabled. Then toggle WhatsApp off and back on in Settings > Apps > WhatsApp > Notifications to re-register it with the system. A quick restart after changing battery and notification settings forces the changes to take effect. See how others solved this on Reddit

Many of the 2024 Moto G Stylus quirks clear up after installing the latest system update via Settings > System > System update, since early firmware shipped with several rough edges. If WhatsApp specifically misbehaves, clear its cache under Settings > Apps > WhatsApp > Storage & cache and reboot. Persistent issues after updating are worth resetting via Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth before any full factory reset. See how others solved this on Reddit
