Video calls have become a daily necessity—whether for work, school, or staying in touch with loved ones. But nothing disrupts the flow like a frozen tablet mid-conversation. You’re speaking, then suddenly everything stops: audio cuts out, your image freezes, and you’re left wondering what went wrong. The frustration is real, but the good news is that most causes of tablet freezing during video calls are fixable with simple, immediate actions.
This guide breaks down the common technical and environmental reasons behind tablet freezes and offers practical solutions you can apply right now. No advanced tech knowledge required—just clear steps to help you stay connected without interruption.
Understanding Why Tablets Freeze During Video Calls
A tablet freezing during a video call isn’t usually due to a single flaw but rather a combination of hardware limitations, software inefficiencies, and network instability. Video calling apps like Zoom, Google Meet, and Microsoft Teams demand significant resources from your device: they use the camera, microphone, processor, memory (RAM), and internet connection simultaneously. When any one of these components struggles, performance suffers—and freezing is often the result.
Common triggers include:
- Insufficient RAM – Older or budget tablets may not have enough memory to handle multitasking during video calls.
- Poor Wi-Fi signal – Weak or unstable internet leads to buffering and app crashes.
- Outdated software – Operating systems and apps need regular updates to run efficiently and securely.
- Overheating – Prolonged use under direct sunlight or on soft surfaces can cause thermal throttling.
- Background apps consuming resources – Other running apps drain battery and slow down performance.
Recognizing these factors helps you diagnose the issue faster and take targeted action.
5 Immediate Fixes to Try Now
If your tablet freezes during a call, don’t wait until it happens again. Apply these five troubleshooting steps immediately to improve stability and prevent future disruptions.
- Restart Your Tablet – A quick reboot clears temporary files, resets memory usage, and stops rogue processes. Hold the power button, select “Restart,” and wait 30 seconds before reopening your video app.
- Switch to a Stronger Wi-Fi Network – Move closer to your router or switch to a less congested network. If possible, avoid using public Wi-Fi for important calls.
- Turn Off Background Apps – Swipe up from the home screen (or use the recent apps button) and close all non-essential applications, especially streaming services, games, or cloud sync tools.
- Lower Video Quality Settings – In your video app settings, reduce resolution to 720p or disable HD video. This reduces bandwidth and processing load.
- Disable Unnecessary Features – Turn off virtual backgrounds, filters, or real-time captions if you don’t need them—they consume extra CPU power.
These steps address the most frequent causes of freezing and often restore smooth performance within minutes.
Long-Term Prevention: Optimize Your Setup
While quick fixes help in the moment, long-term reliability comes from proactive optimization. Consider your tablet as part of an ecosystem—its performance depends on how well all components work together.
Keep Software Updated
Manufacturers release updates to patch bugs, improve security, and enhance efficiency. An outdated operating system or video app can lead to compatibility issues and crashes.
Check for updates regularly:
- iPadOS/Android: Go to Settings > General > Software Update
- Zoom/Meet/Teams: Visit your app store and check for available updates
Enable automatic updates if available, so you never fall behind.
Manage Storage Space
A nearly full tablet slows down significantly. When storage drops below 10%, the system struggles to create temporary files needed for smooth operation. Delete old downloads, unused apps, and duplicate photos to free up space.
“Devices with less than 500MB of free storage can experience severe performance degradation—even during basic tasks.” — Tech Support Bulletin, Android Developers
Cool Down Your Device
Tablets generate heat during extended use. Overheating triggers thermal throttling, where the processor slows down to protect itself, leading to lag and freezing.
To prevent overheating:
- Avoid using your tablet in direct sunlight or hot environments.
- Remove thick cases during long calls to allow better airflow.
- Take short breaks between back-to-back meetings.
Do’s and Don’ts: Tablet Performance Best Practices
| Do | Don’t |
|---|---|
| Use a stable Wi-Fi connection with at least 5 Mbps upload speed | Rely on weak public Wi-Fi for critical calls |
| Close background apps before starting a call | Run multiple video or streaming apps simultaneously |
| Update your OS and apps monthly | Ignore software update notifications |
| Keep at least 1–2GB of free storage | Let storage fill up to 95%+ capacity |
| Use a cooling stand or fan in warm rooms | Leave your tablet in direct sun during calls |
Real-World Example: Maria’s Remote Work Breakthrough
Maria, a freelance graphic designer from Austin, relied on her three-year-old Android tablet for daily client meetings. For weeks, she struggled with freezing during Zoom calls—her screen would stutter every few minutes, making her appear unprofessional.
She tried restarting the app, but the problem persisted. Then, she followed a checklist similar to the one below. First, she discovered her tablet was running an outdated version of Android. After updating, she cleared over 3GB of cached data and uninstalled several unused design apps. She also switched from her living room (far from the router) to a desk near the Wi-Fi base station.
The difference was immediate. Her next call ran smoothly with no lag. “I didn’t realize how much clutter was slowing me down,” she said. “Now I schedule a 10-minute cleanup every Friday to keep things running well.”
Step-by-Step Maintenance Routine
Prevent future freezes with this weekly maintenance routine. It takes less than 15 minutes and ensures your tablet stays reliable.
- Check for Updates (3 min)
Open Settings > System > Software Update. Install any pending OS or app updates. - Clear Cache (4 min)
Go to Settings > Apps > [Video App] > Storage > Clear Cache. Repeat for other high-use apps. - Review Storage (3 min)
Navigate to Settings > Storage. Delete large, unnecessary files (e.g., old videos, downloads). - Test Internet Speed (2 min)
Use a free speed test app. Ensure upload speed is above 3 Mbps for standard video calls. - Reboot the Device (1 min)
Power off completely, wait 10 seconds, then turn back on.
Performing this routine weekly keeps your tablet responsive and minimizes unexpected crashes.
FAQ: Common Questions About Tablet Freezing
Can low battery cause my tablet to freeze during calls?
Yes. When battery level drops below 10–15%, some tablets activate power-saving modes that limit CPU performance. This can cause lag and freezing. Keep your tablet charged above 30% during video calls, or plug it in to maintain stable performance.
Is it better to use a mobile hotspot instead of Wi-Fi?
It depends. A strong 4G/5G mobile hotspot can outperform a weak or overcrowded Wi-Fi network. However, cellular data may have lower upload speeds and data caps. Test both options in your environment to see which delivers more consistent results. Use Wi-Fi when possible, but have a hotspot as a backup.
Will resetting my tablet fix the freezing issue?
A factory reset can resolve deep-seated software problems, but it should be a last resort. Back up your data first, then go to Settings > System > Reset Options > Erase All Data. This returns your tablet to its original state, removing bloatware and corrupted files. Only do this if other fixes fail and freezing continues after multiple troubleshooting attempts.
Expert Insight: What Engineers Say About Tablet Stability
Device performance isn’t just about specs—it’s about balance. Even high-end tablets can struggle if misconfigured.
“The biggest misconception is that more megapixels or a faster processor guarantees smooth video calls. In reality, thermal management, memory allocation, and network handoff efficiency play equally important roles.” — Raj Patel, Senior Mobile Systems Engineer at NetSpeed Labs
Patel emphasizes that users often overlook small optimizations that collectively make a big difference: closing unused apps, managing background sync, and positioning the device properly.
