Latest known WhatsApp problems on Motorola Razr 40
1
Why am I not getting any WhatsApp notifications on my Motorola Razr 40?
On stock Motorola Android, the most common cause is battery optimization killing WhatsApp in the background, so set it to unrestricted under Settings > Apps > WhatsApp > Battery > Unrestricted. Then confirm Settings > Apps > WhatsApp > Notifications is on, and inside WhatsApp open Settings > Notifications and re-enable Message and Group notifications. If it still fails, turn off Adaptive Battery under Settings > Battery, since it can throttle apps it decides you use less often. See how others solved this on Reddit

Why don't I get WhatsApp notifications when my Razr 40 is closed or the screen is off?
When the device is folded or idle, Motorola's power saving puts WhatsApp to sleep, so go to Settings > Apps > WhatsApp > Battery and choose Unrestricted to keep it running while closed. In Settings > Battery, turn off Battery Saver and Adaptive Battery so the system stops suspending background apps. With WhatsApp exempt from optimization, the messaging service stays connected even when the cover screen is off. See how others solved this on Reddit

Can I see WhatsApp notifications on the Razr 40 external (cover) screen?
Yes. The cover display only shows apps you have allowed, so open the cover-screen settings (Settings > Display > Cover display, then the notifications/apps panel) and enable WhatsApp there. WhatsApp's own notifications must also be on under Settings > Apps > WhatsApp > Notifications first, or it won't appear. Note that full quick-reply support on the cover screen is limited on the standard Razr 40 compared with the Ultra, so on some software versions you can view alerts but still need to open the phone to type a long reply.

Why are my WhatsApp messages delayed when sending or receiving on the Razr 40?
Delivery delays almost always trace back to background restrictions, so set WhatsApp to Unrestricted under Settings > Apps > WhatsApp > Battery. Then check Settings > Network & internet > Data Saver and either turn it off or add WhatsApp to unrestricted data access so it can sync in the background. Disabling Adaptive Battery under Settings > Battery also helps, since otherwise the connection sleeps and messages arrive in a burst only when you wake the phone. See how others solved this on Reddit
5
Why did WhatsApp notifications stop showing on my lock screen after the Android 14 update?
Android 14 reset some notification behavior on Motorola devices, so go to Settings > Apps > WhatsApp > Notifications and confirm it is on, then under Settings > Notifications > Notifications on lock screen set it to show all content. Inside WhatsApp, open Settings > Notifications and make sure High priority notifications are on. If it still misbehaves, clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache and reboot. See how others solved this on Reddit

How to install WhatsApp on Motorola Razr 40
1
Choose how to download
On your Motorola Razr 40 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 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.

Happy to help, whatsApp is 100% free to download and use. You only use your normal mobile data or wifi for messages and calls. Hope that helps!

Anyone? my contacts are not showing up in whatsapp pls
AppWhatsOfficialSep 1, 2025
Hi! WhatsApp reads contacts from your phone book, so save the number there with the country code, then pull down to refresh your chat list. Happy chatting!
