How can I fix WhatsApp call glitch?

Fix WhatsApp call cutting out

To fix WhatsApp audio or video calls from glitching and cutting out in the middle, try these 6 step-by-step solutions. 

Check Internet Connection

WhatsApp requires specific bandwidth to keep you connected during audio or video calls. However, your calls will keep cutting out if your cellular data or Wi-Fi connection is slow and experiences packet data loss.

To rectify this, run a speed test on your connection to determine the lag on the network. If the results fall below the minimum requirements for VoIP calls, do the following steps to troubleshoot the network connection issues:

  • Turn on and off the Airplane mode on your phone to refresh the connection. 
  • Unplug the router from the power source for a few seconds and plug it back in.
  • Switch to Wi-Fi or vice versa. 
  • Try moving your phone closer to the router for better Wi-Fi signal reception. 
  • Disconnect other devices connected to your Wi-Fi network for better bandwidth allocation to WhatsApp. 
  • Force close any network-hogging apps running in the device’s background.

NOTE: Since WhatsApp relies on UDP to transmit your call data, contact your ISP to inquire whether your internet connection is correctly configured for this network protocol. 

Disable Bluetooth

Some users report that disabling Bluetooth on Android or iOS devices often stops WhatsApp from continuously dropping calls. 

To do this on your Android, swipe on the Home screen to open the Quick Access Menu, tap “Bluetooth,” and turn it off. If you have an iPhone, do the following steps to turn off Bluetooth:

  • Open “Settings.”
  • Tap “Bluetooth.”
  • Toggle off “Bluetooth.”

Activate Background Data Restrictions

WhatsApp is a VoIP service that relies heavily on an active internet connection to send messages or transmit voice packets during a call. 

However, if you have activated background data restriction for WhatsApp on your phone, the app closes unexpectedly, leading to call interruptions or drops.


To prevent this, turn off the background data restriction for WhatsApp with these steps:

Android: 

  • Open “Settings.”
  • Tap “Connections.”
  • Select “Data Usage.”
  • Select “WhatsApp.”
  • Toggle on “Allow Background Data Usage.”

iPhone:

  • Open “Settings.”
  • Tap “General.”
  • Tap “Background App Refresh.”
  • Toggle on “WhatsApp.”

If enabling the background data restriction doesn’t help, disable the data saver or low data this way:

Android

  • Open “Settings.”
  • Tap “Connections.”
  • Tap “Data Usage.”
  • Select “Data Saver.”
  • Toggle on “Turn On Now.”

iPhone: 

  • Open “Settings.”
  • Go to “Cellular.”
  • Tap “Cellular Data Option.”
  • Tap “Data Mode.”
  • Select “Standard” or “Allow More Data on 5G” to disable “Low Data Mode.”

Once you turn off the low data mode or data saver, go to WhatsApp, make a call, and check if it keeps cutting out. 

Turn off Battery Optimization 

The battery optimization settings on Android limit the background activity of inactive apps to preserve battery power. 

This feature often interferes with your WhatsApp calls and causes them to keep cutting out. In this case, the fix here is to turn off the battery optimization feature on your phone with these steps: 

  • Open “Settings.”
  • Tap “Battery and Device Care.”
  • Tap “Battery.”
  • Select “More Battery Settings.”
  • Toggle off “Adaptive Battery” and check if this fixes the issue. 

Disable Router Security And Firewall Settings

It’s possible your router security and firewall settings are blocking specific connections necessary for VoIP calls through WhatsApp. As a result, your calls keep cutting out in the middle of your conversations.

To prevent this, turn off firewall settings on your router with the steps given below:

  • Open a browser and type in the router’s IP address.
  • Enter your router admin page credentials.
  • Go to “Security Settings.”
  • Click “Firewall.”
  • Select “Disable.”
  • Click “Save” or “Apply” and verify the fix.

NOTE: The steps to turn off firewall settings might differ based on the make and model of your router. 

Clear WhatsApp Cache 

Bulky or corrupt WhatsApp cache data on your phone sometimes conflict with the app resources to handle audio or video calls, due to which you experience frequent dropouts or connecting issues. 

Your best bet here is to clear the WhatsApp cache data by following these steps: 

Android: 

  • Open “Settings.”
  • Tap “Apps.”
  • Tap “All Apps.”
  • Select “WhatsApp.”
  • Tap “Storage.”
  • Tap “Clear Cache.”
  • Select “Clear Data.”
  • Tap “OK.”

iPhone:

  • Open “Settings.”
  • Tap “General.”
  • Go to “iPhone Storage.”
  • Select “WhatsApp.”
  • Tap “Offload App.”
