WhatsApp for Motorola Razr 50

On the Razr 50, audio is tied to the active display, so folding the phone shut interrupts voice-message and call playback by default. Open Settings > Display > External display (or the Moto app > External display panel) and enable WhatsApp so the app continues running on the cover screen, then keep playback going there. As a workaround, route audio to Bluetooth earbuds before folding, which keeps the stream alive regardless of the screen state. See how others solved this on Reddit

This black-screen glitch is usually a rendering bug between WhatsApp and Motorola's display switching, often appearing after an update. First force-stop the app in Settings > Apps > WhatsApp > Force stop, then clear its cache (Storage > Clear cache, not Clear data) and reopen it. If it persists, update WhatsApp from the Play Store and toggle Settings > System > Developer options > Disable HW overlays, which resolves the blank chat view on many Razr units.

Delayed notifications on the Razr 50 are almost always caused by aggressive battery optimization killing WhatsApp in the background. Go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted, then check Settings > Battery > Battery optimization and exclude WhatsApp. Also confirm Settings > Apps > WhatsApp > Notifications is fully enabled and that you haven't left Do Not Disturb or the cover-screen notification filter active.

WhatsApp Pay failures on the Razr 50 usually come from SMS verification not completing, which the bank uses to link your account. Make sure the SIM tied to your bank account is in the phone, that Settings > Apps > WhatsApp > Permissions has SMS and Phone enabled, and that you have a working data connection during setup. If it still fails, remove and re-add the payment method in WhatsApp > Settings > Payments, and verify your number isn't being blocked by a default SMS app or spam filter.

The Razr 50's tall screen and Motorola's video scaling can force videos taken on the phone to fill the display, cutting off the edges. In the WhatsApp video player tap the screen and look for the fit/crop toggle (the expand icon) to switch back to the original aspect ratio. If that doesn't stick, check Settings > Display > Aspect ratio for WhatsApp and set it to Fit to screen rather than Full screen so clips aren't stretched. See how others solved this on Reddit

Yes, but apps aren't enabled on the external display by default on the Razr 50. Open the Moto app (or Settings > Display > External display) and toggle WhatsApp on under the running-apps list, after which you can open and reply to chats without unfolding. Note that some full-screen actions like video calls may prompt you to open the phone, but text, voice notes, and quick replies work directly on the cover. See how others solved this on Reddit
