Why don't WhatsApp calls go through on Android, but messages arrive - briefly?
The issue of WhatsApp calls not going through on Android while messages arrive briefly is often due to network connectivity problems or software bugs. To resolve this, ensure your device has a stable internet connection and consider updating the app to the latest version.
Why don't WhatsApp calls go through on Android, but messages arrive - in detail?
The discrepancy between successful message delivery and failed voice or video calls on WhatsApp for Android can be attributed to several factors related to network connectivity, device settings, and app permissions.
Firstly, WhatsApp messages are designed to be highly resilient and can often be delivered even over weak or unstable connections. This is because the platform uses end-to-end encryption and a robust messaging protocol that breaks down larger messages into smaller packets, which are then reassembled at the recipient's end. If initial delivery attempts fail due to poor connectivity, WhatsApp can retry sending these packets multiple times until they successfully reach the recipient.
In contrast, voice and video calls on WhatsApp require a more stable and continuous connection. These types of communications are real-time and cannot afford delays or interruptions without significantly impacting the user experience. Therefore, if the network conditions deteriorate during a call setup or while the call is in progress, the system may terminate the call to maintain quality standards.
Another critical factor contributing to this issue could be related to device settings and permissions. On Android devices, various background restrictions and battery optimization features can interfere with WhatsApp's ability to maintain a stable connection for calls. For instance, if the app is restricted from running in the background or if data saver modes are enabled, these settings can limit WhatsApp’s access to necessary resources, leading to failed call attempts while messages might still go through.
Moreover, network operators may implement specific policies that prioritize certain types of traffic over others. In some cases, voice and video calls might be deprioritized in favor of messaging data, especially if the network is congested or experiencing heavy usage. This can result in successful message delivery but failed call attempts.
In summary, the difference in the behavior of WhatsApp messages versus calls on Android devices stems from the varying requirements for continuous connectivity and stability between these two types of communications. While messages are designed to be resilient and can withstand network fluctuations, calls demand a more consistent connection, making them more susceptible to failure under suboptimal conditions. Addressing network issues, optimizing device settings, and ensuring appropriate permissions can help mitigate the problem and improve call reliability on WhatsApp for Android users.
