Video calls have become a staple of modern communication—whether for remote work, virtual learning, or staying in touch with loved ones. But nothing disrupts the flow like a frozen screen on your tablet mid-conversation. The audio cuts out, your image stalls, and you're left disconnected, often embarrassed. While frustrating, this issue is rarely random. Most freezes stem from predictable technical limitations or environmental factors that can be diagnosed and resolved. Understanding the root causes—and knowing how to address them—can transform your video calling experience from unreliable to seamless.
Common Causes of Tablet Freezing During Video Calls
Tablets are powerful devices, but they operate within constraints. When multiple systems compete for limited resources, performance suffers. Video calling apps demand significant processing power, memory, and network bandwidth. When one or more components fail to keep up, freezing occurs. The following are the most frequent culprits behind tablet freezes during video calls.
1. Insufficient RAM or Processor Overload
Modern video conferencing apps like Zoom, Google Meet, and Microsoft Teams require substantial memory (RAM) and CPU power to run smoothly. Tablets with lower RAM—especially older models with 2GB or less—are prone to lag when running background apps alongside a video call. The processor may struggle to encode and decode high-resolution video in real time, leading to stuttering or complete freezes.
2. Poor or Unstable Internet Connection
A stable internet connection is critical for smooth video transmission. Even if your Wi-Fi shows full bars, signal strength doesn’t guarantee consistent bandwidth. Interference from walls, distance from the router, or network congestion from other devices can cause packet loss or latency spikes. When data fails to transmit quickly enough, the app buffers or freezes to compensate.
3. Outdated Operating System or App Software
Manufacturers regularly release updates to improve stability, security, and performance. An outdated OS or video calling app may contain bugs that interfere with resource management or compatibility. For example, an old version of Skype might not optimize video encoding efficiently on a newer Android build, leading to crashes.
4. Overheating Due to Prolonged Use
Extended video calls generate heat, especially when the camera, microphone, screen, and processor are all active. Tablets lack advanced cooling systems, so internal temperatures can rise quickly. When a device overheats, it throttles performance to protect hardware—slowing down the processor and causing apps to freeze or shut down unexpectedly.
5. Storage Space Depletion
When a tablet’s storage is nearly full—typically above 90% capacity—the system struggles to manage temporary files and cache. This slowdown affects all operations, including real-time tasks like video decoding. Apps may freeze because they can’t write necessary session data or access cached media quickly enough.
“Thermal throttling and memory fragmentation are silent killers of tablet performance during video calls. Many users don’t realize their device is struggling until it freezes.” — Dr. Alan Reyes, Mobile Systems Engineer at TechInsight Labs
Step-by-Step Guide to Fix a Freezing Tablet During Video Calls
Instead of reacting after a freeze, take proactive steps to stabilize your device. Follow this sequence to diagnose and resolve the most likely issues.
- Restart Your Tablet – A simple reboot clears temporary memory, stops rogue processes, and resets network connections. It’s the fastest way to resolve minor software glitches.
- Close Background Apps – Swipe through open apps and close any unnecessary ones, particularly browsers, streaming services, or games that consume memory.
- Check Wi-Fi Signal Strength – Move closer to your router or switch to a 5GHz band if available. Avoid using public or crowded networks.
- Test Internet Speed – Use a speed test tool to confirm upload and download speeds. For HD video calls, aim for at least 3 Mbps download and 1.5 Mbps upload.
- Update the Operating System and App – Go to Settings > System > Software Update to check for OS patches. Also update your video calling app via the App Store or Google Play.
- Clear App Cache – On Android: Settings > Apps > [App Name] > Storage > Clear Cache. On iPad: Offload and reinstall the app to clear cached data.
- Free Up Storage Space – Delete unused apps, photos, and downloads. Aim to keep at least 15–20% of total storage free.
- Monitor Device Temperature – If the tablet feels hot, pause the call, turn it off for a few minutes, and let it cool down before resuming.
Do’s and Don’ts: Best Practices for Stable Video Calls
| Do’s | Don’ts |
|---|---|
| Use a wired Ethernet adapter with a USB-C or Lightning hub for maximum stability | Run multiple video apps simultaneously (e.g., Zoom and YouTube) |
| Enable “Low Data Mode” in your video app settings to reduce bandwidth usage | Place your tablet in direct sunlight or on warm surfaces during calls |
| Keep your tablet charged above 30% to prevent power-saving throttling | Ignore software update notifications for weeks or months |
| Use headphones with a built-in mic to reduce processing load from speakerphone | Leave dozens of browser tabs open while on a call |
| Position your tablet near the router or use a Wi-Fi extender | Assume full Wi-Fi bars mean strong performance |
Real-World Example: How Sarah Fixed Her Weekly Team Calls
Sarah, a project manager based in Chicago, relied on her 4-year-old iPad for weekly team meetings. Every Thursday, around 15 minutes into the call, her screen would freeze, forcing her to disconnect and rejoin. At first, she blamed her internet, but her laptop worked fine on the same network. After reading about device-specific issues, she investigated her iPad.
She discovered her storage was 97% full—mostly from old screenshots and unwatched training videos. She also had five apps running in the background, including a music streaming service. After deleting unused files, closing apps, and restarting the device, her next call ran without a single hiccup. Later, she updated her iOS version and enabled “Reduce Motion” in Accessibility settings, further improving responsiveness. Now, her calls are consistently smooth, and her team no longer jokes about her “disappearing act.”
Troubleshooting Checklist: Prevent Future Freezes
Use this checklist before every important video call to minimize the risk of freezing:
- ✅ Restart the tablet 5–10 minutes before the call
- ✅ Close all background apps
- ✅ Connect to a 5GHz Wi-Fi network (if available)
- ✅ Disable Bluetooth devices not in use
- ✅ Ensure battery level is above 30%
- ✅ Confirm the video app is updated to the latest version
- ✅ Clear cache for the video calling app monthly
- ✅ Keep the device in a cool, shaded area during long calls
- ✅ Test audio and video in advance using the app’s pre-call diagnostic
- ✅ Have a backup device ready (e.g., smartphone or laptop)
Frequently Asked Questions
Can antivirus apps help prevent freezing during video calls?
Most tablets do not benefit significantly from third-party antivirus apps. Unlike PCs, mobile operating systems restrict app behavior for security. However, malware can still affect performance. Stick to official app stores and avoid sideloading unknown apps. If you suspect malware, perform a factory reset after backing up essential data.
Is it better to use cellular data or Wi-Fi for video calls?
Wi-Fi is generally more stable and cost-effective for video calls. However, if your home Wi-Fi is congested or weak, a strong 5G or LTE connection can be a reliable alternative. Just ensure you’re not near your data cap, as HD video calls can use 200–300 MB per hour.
Why does my tablet freeze only during front-camera calls?
The front camera often runs at higher resolution for portrait optimization, increasing processing demands. Additionally, some apps apply real-time filters or beauty effects by default, which consume extra GPU resources. Disable these features in app settings to reduce strain.
Optimizing Long-Term Performance
Preventing freezes isn’t just about quick fixes—it’s about sustainable device care. Treat your tablet like any precision tool: regular maintenance ensures longevity and reliability. Schedule a monthly “health check” where you review storage, delete unused apps, and install pending updates. Consider using cloud storage (Google Drive, iCloud) to offload large files like videos and photos. Enable automatic app updates to stay current without manual effort.
For households with multiple users, set up Quality of Service (QoS) rules on your router to prioritize video call traffic. This ensures your tablet gets sufficient bandwidth even when others are streaming or gaming. Finally, invest in a tablet stand and external microphone to reduce handling and improve audio quality, indirectly reducing the need for repeated call adjustments that stress the system.
Conclusion: Take Control of Your Video Call Experience
A frozen tablet during a video call doesn’t have to be inevitable. With a clear understanding of the underlying causes—be it insufficient RAM, poor connectivity, or thermal throttling—you can implement targeted solutions that restore smooth performance. Small habits, like closing background apps and updating software, make a significant difference over time. Technology should serve you, not frustrate you. By applying these strategies consistently, you’ll not only eliminate freezes but also extend the lifespan of your device.
