WhatsApp is one of the most popular messaging apps in the world, used by billions of people daily to communicate with friends, family, colleagues, and more. However, like any technology, WhatsApp can occasionally encounter issues that prevent the app from working properly. There are various potential reasons why WhatsApp may stop working or become unresponsive on your device. The aim of this article is to explore the most common issues that can cause problems with WhatsApp and provide troubleshooting tips to help get the app working again.
Why is WhatsApp Not Connecting?
One of the most common issues that can prevent WhatsApp from working correctly is struggling to connect to the app. There are a few typical reasons this can happen:
No Internet Connection
For WhatsApp to work, it requires an active internet connection. This can be either Wi-Fi or mobile data. If you don’t have an internet connection on your device for any reason, WhatsApp will be unable to connect to WhatsApp’s servers and the app will not work. Make sure that Wi-Fi is turned on and connected or that mobile data is enabled if using a mobile network. Also check that the internet connection is working correctly by trying to load a website.
Poor Internet Connection
While you may have an internet connection, there could be issues with the connection preventing WhatsApp from working properly. A slow, unstable or weak internet connection can stop WhatsApp connecting correctly. Restarting your router or switching from Wi-Fi to mobile data may help in this case.
WhatsApp Server Issues
Though less common, sometimes connectivity issues with WhatsApp are due to problems on WhatsApp’s servers. Server outages or technical issues can prevent WhatsApp from working properly for multiple users. Usually these server-side problems are resolved within a few hours. Check WhatsApp’s Twitter account or status website for updates if you think issues connecting may be due to WhatsApp server problems.
Incorrect Date/Time Settings
WhatsApp relies on having the correct date and time settings on your device to connect to its service. If your date or time settings are inaccurate, it can cause synchronization problems and stop WhatsApp working. Make sure that the date and time on your device are set correctly using automatic settings.
Why is My WhatsApp Not Sending or Receiving Messages?
Another common WhatsApp issue is when the app is connected but messages are unable to be sent or received. There are some things to check in this scenario:
No Internet Connection
As explained above, an internet connection is essential for sending and receiving WhatsApp messages. If you’ve lost your internet connection, messages will queue but not actually send until the connection is restored. Make sure you’re connected to the internet and try sending messages again.
Contact Blocked You
If a contact has blocked your number in their WhatsApp settings, messages you send to them will not be delivered and you won’t see their message updates. Unfortunately the only solution is to have the contact unblock your number.
New Phone Number
If you or a contact has recently changed mobile number, it can cause temporary issues with sending/receiving messages until the number change registers on WhatsApp’s system. Give it a few hours and messaging should start working normally.
Incorrect Notification Settings
Make sure that notifications for WhatsApp are enabled in your device settings. If they are disabled, you won’t receive notifications when new WhatsApp messages arrive, even though the messages are being received normally within the app. Check notification settings and make sure WhatsApp notifications are turned on.
Too Many Messages
If you are suddenly receiving a flood of WhatsApp messages, the rate of incoming messages may exceed WhatsApp’s ability to display notifications instantly. After the message flood slows down, notification behavior should return to normal.
Out of Storage Space
If your device runs completely out of free storage space, it can cause issues sending and receiving WhatsApp media, like photos. Free up storage space on your device and then try sending/receiving media files again.
Why Does the WhatsApp Camera Not Work?
WhatsApp has a built-in camera feature that lets you take and send photos/videos directly within chats. But sometimes this camera feature stops working correctly. Some potential reasons:
No Storage Space
As mentioned above, running out of storage space can cause problems with WhatsApp media capabilities. Make sure you have enough free space for WhatsApp to save photos/videos taken using its camera.
Outdated App
An outdated version of the WhatsApp app may have bugs or issues with the camera function. Check the App Store/Google Play Store and update WhatsApp to the latest version if an update is available. The release notes often mention bug fixes.
Camera Permissions
For WhatsApp to access your device’s camera, it needs permission to do so. Open your device settings and make sure WhatsApp has permission to use the phone’s camera. Enable camera access if it has been disabled.
Poor Lighting Conditions
In very low-light scenes, the WhatsApp camera may struggle to focus properly or capture a good image. Switch on the phone’s flash or move to a location with brighter lighting conditions and try using the WhatsApp camera again.
Buggy Camera App
If the regular camera app on your device is also glitchy or crashing, there may be a system-wide camera problem on your phone rather than just with WhatsApp’s integration. Update your device software, camera app, and check camera settings to identify any OS-level camera issues.
Why Does My WhatsApp Keep Crashing?
Frequent app crashes or freezes when trying to use WhatsApp can make the messaging app extremely difficult to use. But what causes the problems? Here are some potential crash-related issues:
Outdated App Version
Like any app, new WhatsApp updates often contain important bug fixes. An outdated app version could be more prone to crashing, so update WhatsApp to eliminate any fixed issues.
Insufficient Device Storage
As mentioned previously, running very low on device storage can lead to instability and app crashes. Free up space if your phone is nearly full when WhatsApp crashes occur.
Overheating Device
Excessive device overheating can sometimes cause apps to crash and phone instability in general. This may especially affect devices with an older or underpowered processor. Close all apps and let the phone cool down before reopening WhatsApp.
App Conflicts
Rarely, there may be conflicts between WhatsApp and other apps installed on your device leading to crashes. Try uninstalling recently installed apps to see if this improves WhatsApp stability.
OS or Firmware Bugs
Bugs in your device’s operating system or firmware can sometimes trickle down to cause app instability. Updating to the latest OS version or firmware update may help resolve OS-level bugs affecting WhatsApp.
Corrupt App Data
In some cases, corrupted or damaged app data can cause WhatsApp to crash repeatedly. Try uninstalling and reinstalling WhatsApp to reset the app data which may resolve corruption issues.
Disabled Background App Refresh
If background app refresh is disabled for WhatsApp, important data may not sync properly in the background, leading to crashes when opening the app. Double check that background app refresh is enabled.
Why is My WhatsApp Slow?
In addition to outright app crashes, a slow, laggy, and sluggish WhatsApp experience can also make the messaging app difficult to use. Potential performance issues may include:
Too Many Media Files
If your chats contain a very high number of media files like photos and videos, the app may struggle to quickly load all this data, slowing things down. Try deleting old media or backing it up to external storage.
Full Storage
As mentioned a few times already, low device storage can significantly slow down WhatsApp and other apps due to the lack of free space for temporary data and caches. Free up ample storage space if available space is minimal.
Outdated App/OS
Using an outdated version of the WhatsApp app or an old version of your phone’s operating system can lead to degraded performance as new updates contain speed optimization fixes. Update WhatsApp and your device OS to latest versions.
Too Many Messages
If chats contain thousands of messages, especially with lots of media content, WhatsApp may have trouble loading all this historical data quickly, slowing down usage. Archive very old chats you don’t need immediate access to.
Weak Internet Connection
Slow and unstable internet connections can hamper WhatsApp’s performance when loading data from its servers. Switch to a faster, more reliable Wi-Fi network or use mobile data if on a weak public Wi-Fi connection.
Third-party Launchers
Some third-party launcher apps do not optimize WhatsApp well, causing lag on certain devices. Switch back to your device’s standard launcher for improved performance.
Hardware Issues
On very old phones with outdated processors, limited RAM, and storage, WhatsApp may be slow simply due to the phone’s hardware constraints. Upgrading your device can help in this scenario.
How to Fix “WhatsApp Call Not Working” Issues
Along with messaging, WhatsApp also allows users to make free voice and video calls within the app. But you may encounter issues when trying to make calls, such as:
No Internet Connection
As with messaging, WhatsApp calls require a stable internet connection to function, whether on Wi-Fi or mobile data. Ensure you are connected to the internet and troubleshoot any connection issues.
Outdated App Version
Buggy app versions can sometimes break call functionality. Keep the WhatsApp app updated to the latest release to ensure optimal call performance.
Call Permissions
Make sure WhatsApp has permission to access your microphone and camera for call capabilities. Enable these permissions in your device settings if they have been disabled.
Do Not Disturb Active
If Do Not Disturb mode is enabled on your device during a call attempt, the call may fail or you may not receive the incoming call. Make sure DND is disabled at the desired times.
Phone Software Bug
As with the camera, software bugs at the OS level can sometimes interfere with WhatsApp’s calling feature. Updating your device’s operating system may resolve system-level call issues.
Temporary Server Problem
In rare cases, WhatsApp’s servers may encounter temporary voice/video call problems that prevent calls from connecting. Try again after some time or check WhatsApp’s status page for any known issues.
Call Settings
Make sure WhatsApp’s call settings are correctly configured, with calls enabled, correct notification preferences, and a suitable cellular/Wi-Fi preference selected for data usage.
Troubleshooting Tips When WhatsApp is Not Working on Android
On the Android operating system, here are some additional troubleshooting steps if you are experiencing problems with WhatsApp:
Check Play Store Reviews
Recent WhatsApp reviews on the Google Play store can give insight into common issues users are encountering after an app update. Downgrade the app if necessary.
Clear App Data/Cache
Open device settings, select apps, then WhatsApp, and try clearing the app data and cache. This resets the app and eliminates corrupt data.
Uninstall Updates
From WhatsApp’s app info page in settings, select uninstall updates to revert WhatsApp to the default factory version. This removes potentially problematic updates.
Restart in Safe Mode
Boot your Android device into safe mode and try using WhatsApp to isolate if third-party apps are causing conflicts. Instructions vary by device but hold power + volume down on start usually works.
Factory Reset Device
As a last resort, a full factory reset of your Android device can eliminate any persistent software issues including problems with WhatsApp. Back up important data first.

When Should You Reinstall WhatsApp?
If you’ve tried all standard troubleshooting steps but WhatsApp is still malfunctioning, reinstalling the app is one last option before factory resetting your device. Reasons you may want to reinstall WhatsApp include:
- Persistent app crashes, freezes, or force closes.
- Endless connection issues.
- Ongoing problems sending/receiving messages.
- Features like calls or camera aren’t working.
- Major app performance problems.
- Weird visual glitches or bugs.
Before reinstalling, remember to back up your WhatsApp data and any media files you want to keep. On Android, use built-in WhatsApp backup before uninstalling the app. On iPhone, iCloud or iTunes backups store WhatsApp content.
To reinstall WhatsApp, delete the app from your device, restart your phone, then freshly install WhatsApp again from the app store. Restore backups during setup. This gives you a clean slate and may resolve stubborn software issues.
Only reinstall as a last resort after trying simpler troubleshooting steps first, as you may lose recent unsaved data. But for persistent major problems, a reinstall is worth trying before a full device reset.
Preventing WhatsApp Issues
While WhatsApp problems can be frustrating, there are some measures you can take to prevent certain issues in the first place:
- Keep WhatsApp updated to the latest version.
- Back up your messages/media regularly.
- Don’t overload chats with thousands of messages/media files.

- Maintain adequate storage space on your device.
- Use a stable Wi-Fi or mobile data connection.
- Keep your device OS and core apps up-to-date.
Following these best practices will minimize potential issues and keep WhatsApp running more smoothly overall.
