Latest known WhatsApp problems on Motorola Razr 40 Ultra
1
Why is there a long delay sending and receiving WhatsApp messages on my Razr 40 Ultra?
This is almost always battery optimization throttling WhatsApp in the background. Go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted, then open Settings > Battery > Battery optimization, find WhatsApp and set it to Don't optimize; also turn off any aggressive power-saving or 'optimized charging' mode. Keeping the app whitelisted lets it hold a live connection so messages arrive instantly instead of only when you open the app. See how others solved this on Reddit

WhatsApp notifications aren't showing up on my Razr 40 Ultra, how do I fix it?
First make sure WhatsApp isn't being killed in the background: Settings > Apps > WhatsApp > Battery > Unrestricted. Then check Settings > Apps > WhatsApp > Notifications and confirm the Messages and Groups channels are enabled with sound, and inside WhatsApp go to Settings > Notifications and toggle them back on. A quick reboot after changing these settings forces the push service to re-register so alerts come through reliably. See how others solved this on Reddit
3
Can I see WhatsApp notifications on the Razr 40 Ultra's external cover screen?
Yes, but the cover display only shows apps you explicitly allow. Open the Moto app > Display > External display (or Settings > Display > External display) and enable WhatsApp in the list of permitted apps, then make sure WhatsApp's own notifications are turned on. Once added, you can read and reply to messages from the cover screen without opening the phone. See how others solved this on Reddit

WhatsApp opens to a black screen when I tap a conversation on my Razr 40 Ultra, what should I do?
This is a known rendering glitch, often tied to a stale app cache or the cover-screen/folding transition. Go to Settings > Apps > WhatsApp > Storage and tap Clear cache (not Clear data), then force stop and reopen the app. Also update both WhatsApp and Android System WebView in the Play Store, since an outdated WebView commonly causes blank views. If it persists, reinstalling WhatsApp clears the corrupted view state. See how others solved this on Reddit
5
Why do WhatsApp voice messages cut out or fail to record on my Razr 40 Ultra?
This usually comes from a microphone permission or background-recording conflict. Check Settings > Apps > WhatsApp > Permissions and make sure Microphone is set to Allow, then confirm no other app (like a call recorder or assistant) is holding the mic. Clearing WhatsApp's cache (Settings > Apps > WhatsApp > Storage > Clear cache) and updating to the latest version from the Play Store resolves most recording and playback dropouts. See how others solved this on Reddit
6
WhatsApp payments won't work on my Razr 40 Ultra in India, how can I set it up?
WhatsApp Pay (UPI) needs the SIM with your bank-linked number active in the phone and SMS verification to go through, so confirm WhatsApp has SMS and Phone permissions under Settings > Apps > WhatsApp > Permissions. Make sure the app is fully updated and your number exactly matches the one registered with your bank. If verification still fails, remove and re-add the payment method, or reinstall WhatsApp to force a fresh UPI registration. See how others solved this on Reddit

How to install WhatsApp on Motorola Razr 40 Ultra
1
Choose how to download
On your Motorola Razr 40 Ultra you can get the official app two ways: from the Google Play Store — the easiest option, since it keeps WhatsApp updated automatically — or directly from the official website. You can download an APK file, by clicking a link “Download WhatsApp directly”.
2
Open WhatsApp
Launch WhatsApp from your home screen or app drawer and accept the Terms of Service to start setup.
3
Verify your phone number
Enter your phone number. If your Motorola Razr 40 Ultra uses dual SIM, pick the line you want WhatsApp tied to, then enter the 6-digit code it sends by SMS — it usually fills in automatically.
4
Restore chats and finish setup
Restore your chat history from Google Drive (use the same Google account), add your name and photo, and tap Allow for notifications so messages and calls arrive reliably.
Stay safe: only ever install WhatsApp from the official Android source. The Download button above already points there — modified copies (GB/Plus/Aero WhatsApp) can get your number banned.

anyone? i lost my old chats can i get them back pls
AppWhatsOfficialMay 24, 2025
No worries, if you made a backup before, sign in with the same number and tap Restore when asked. WhatsApp pulls your chats from the cloud backup. Feel free to ask if you get stuck.

pls help the app opens to a black screen thanks
AppWhatsOfficialAug 23, 2024
Happy to help, a black screen usually clears after a restart. If not, reinstall the newest version and it should open fine. Feel free to ask if you get stuck.
