Common Symptoms of WhatsApp Malfunctioning
Before diving into solutions, let’s identify what “not working” might look like:
Messages not sending or receiving: Stuck on one tick, or messages appear delayed.
Calls failing or poor quality: Voice/video calls not connecting or constantly dropping.
App crashing or freezing: WhatsApp closes unexpectedly or becomes unresponsive.
Notifications delayed or absent: You only see messages when you open the app.
Media not downloading or uploading: Photos, videos, or documents fail to send or receive.
“WhatsApp not responding” error messages.
WhatsApp Web/Desktop not connecting.

Why is This Happening? Common Causes
Understanding the root cause can sometimes help pinpoint the solution faster. Common reasons for WhatsApp issues include:
Internet Connectivity Problems: The most common culprit.
Outdated App or Operating System: Bugs in older versions.
Corrupted App Cache or Data: Temporary files gone rogue.
Incorrect App Permissions: WhatsApp can’t access what it needs (microphone, storage, etc.).
Aggressive Battery Optimization: Realme UI might be killing background processes.
Full Internal Storage: Not enough space for the app to function.
WhatsApp Server Issues: Although rare, it’s possible.
Software Glitches/Bugs: Within WhatsApp or the Realme UI itself.

The Ultimate Troubleshooting Steps (From Simple to Advanced)
Let’s get your WhatsApp working again! Follow these steps in order, testing WhatsApp after each one.
1. Basic Checks (The Quick Fixes)
Restart Your Realme 12 Series Phone:
* This is the classic “turn it off and on again” solution, and it often works wonders by clearing minor software glitches.
* Hold down the Power button for a few seconds and select Restart.
Check Your Internet Connection:
* Wi-Fi: Ensure your Wi-Fi is connected and has internet access. Try opening a browser or another app. If other apps also struggle, the issue is likely your Wi-Fi router or ISP.
* Mobile Data: Turn off Wi-Fi and try using mobile data. Ensure you have an active data plan and good signal strength.
* Toggle Airplane Mode: Turn on Airplane Mode for 30 seconds, then turn it off. This resets your network connection.
* Switch Between Wi-Fi and Mobile Data: Sometimes one works better than the other.
Check WhatsApp Server Status:
* While rare, WhatsApp’s servers can experience outages. You can quickly check websites like DownDetector (downdetector.com) to see if other users are reporting problems globally. If it’s a server issue, you’ll just have to wait.
2. WhatsApp App-Specific Solutions
Update WhatsApp:
* An outdated app version can have bugs that newer versions have fixed.
* Open the Google Play Store.
* Tap your profile icon (top right).
* Tap Manage apps & device.
* Look for WhatsApp and tap Update if an update is available.
Clear WhatsApp Cache:
* The app cache stores temporary data to make the app load faster. However, a corrupted cache can cause issues. Clearing it won’t delete your chats.
* Go to Settings > Apps > App management.
* Find and tap on WhatsApp.
* Tap Storage usage.
* Tap Clear cache.
* Restart WhatsApp and see if the problem is resolved.
Clear WhatsApp Data (Use with Caution – Backup First!):
* This will reset WhatsApp to its initial state, effectively “reinstalling” it without deleting the app itself. You MUST have a recent Google Drive backup of your chats before doing this, or you will lose all your chat history.
* First, verify your backup: Open WhatsApp > Settings > Chats > Chat backup. Ensure there’s a recent backup to Google Drive.
* Go to Settings > Apps > App management.
* Find and tap on WhatsApp.
* Tap Storage usage.
* Tap Clear data (or Clear storage).
* You’ll then need to set up WhatsApp again, verifying your phone number and restoring your chats from Google Drive.
Reinstall WhatsApp (Last Resort for App-Specific Issues):
* If clearing data doesn’t work, a complete reinstallation might. Again, ensure you have a recent Google Drive backup.
* Backup WhatsApp chats (Settings > Chats > Chat backup).
* Uninstall WhatsApp: Press and hold the WhatsApp icon on your home screen or app drawer, then tap Uninstall. Alternatively, go to Settings > Apps > App management > WhatsApp > Uninstall.
* Restart your phone.
* Reinstall WhatsApp from the Google Play Store.
* Open WhatsApp, verify your number, and restore your chats from your Google Drive backup.
3. Realme 12 Series System Settings Specific Solutions
Check App Permissions for WhatsApp:
* WhatsApp needs certain permissions to function correctly (e.g., access to contacts, microphone, camera, storage). Realme UI might restrict these.
* Go to Settings > Apps > App management.
* Find and tap on WhatsApp.
* Tap Permissions.
* Ensure all necessary permissions (like Camera, Contacts, Microphone, Notifications, Phone, Storage) are Allowed. If any are “Denied,” tap on them and select “Allow.”
Disable Battery Optimization for WhatsApp:
* Realme UI’s battery optimization can sometimes be aggressive, killing background apps to save power, which can lead to delayed notifications or messages.
* Go to Settings > Apps > App management.
* Find and tap on WhatsApp.
* Tap Battery usage.
* Select Unrestricted. This tells the system not to optimize WhatsApp’s battery usage, allowing it to run freely in the background.
Keep WhatsApp in Recent Apps (App Lock):
* In the recent apps screen, you can sometimes “lock” apps to prevent them from being cleared from memory.
* Open WhatsApp, then go to your recent apps view (swipe up from the bottom and hold, or tap the recent apps button).
* Tap the three dots (or lock icon) on the top right corner of the WhatsApp app card.
* Select Lock. This will put a small lock icon on the app, indicating it won’t be killed easily.
Update Realme UI (System Software):
* A bug in your phone’s operating system (Realme UI) could be causing conflicts. System updates often include bug fixes and performance improvements.
* Go to Settings > About device.
* Tap on Realme UI version (or “Up to date” / “Updates available”).
* Check for and install any available system updates.
Check Internal Storage:
* If your phone’s storage is nearly full, apps can become unstable and fail to function correctly.
* Go to Settings > About device > Storage.
* If your storage is almost full, delete unnecessary files, old photos/videos, or unused apps.
4. Network Settings Reset
If you suspect network issues despite your internet working for other apps, resetting network settings might help. This will reset Wi-Fi, mobile data, and Bluetooth settings, but won’t delete your personal data. You’ll need to re-enter Wi-Fi passwords.
* Go to Settings > System settings > Backup & reset > Reset phone.
* Tap Reset network settings.
* Confirm your PIN/password.
5. Factory Reset (The Absolute Last Resort)
If nothing else* works, and you’re still experiencing persistent WhatsApp issues, a factory reset might be the only option. This will erase ALL data from your phone, returning it to its out-of-the-box state.
Crucially, back up EVERYTHING – photos, videos, documents, contacts, app data – to Google Drive, a computer, or an external drive before proceeding.
Go to Settings > System settings > Backup & reset > Reset phone.
Tap Erase all data.
Confirm your PIN/password and follow the on-screen instructions.
After the reset, set up your phone and reinstall WhatsApp, restoring your chat backup.

When to Seek Professional Help

Contact Realme Support: They might have specific diagnostic tools or be aware of known issues for your device model.
Visit an Authorized Service Center: A technician can physically inspect your device.
Contact WhatsApp Support: While they generally defer to device manufacturers for phone-specific issues, they might offer insights if it’s a known app bug.
