Video calls have become essential for work, education, and staying connected with loved ones. Yet nothing disrupts the flow like a frozen tablet mid-conversation. The screen locks up, audio cuts out, and you're left awkwardly waving at a still image of yourself. While hardware limitations can contribute, most freezing issues stem from software inefficiencies, outdated systems, or misconfigured settings. Understanding the root causes—and knowing how to fix them—can restore reliability and confidence in your device.
Tablets are powerful, but they operate under constraints: limited RAM, background processes, and real-time data demands during video conferencing. When these factors collide, performance suffers. Fortunately, many of these problems are preventable or resolvable through proper maintenance, timely updates, and smart usage habits.
Understanding Why Tablets Freeze During Video Calls
A frozen tablet during a video call is rarely random. It typically results from one or more underlying issues related to system resources, app behavior, or network instability. Recognizing these triggers is the first step toward resolution.
Resource Overload: Video calling apps like Zoom, Google Meet, and Microsoft Teams demand significant processing power, especially when handling high-definition video, real-time encoding, and background noise suppression. If your tablet is simultaneously running multiple apps or services, available memory (RAM) may be insufficient, leading to lag or complete freeze.
Outdated Software: Operating systems and applications receive regular updates that improve stability, patch security flaws, and optimize performance. Running an older version of Android, iPadOS, or a video app increases the risk of bugs that cause crashes or unresponsiveness.
Background Processes: Even when not in use, apps can run in the background—syncing data, updating notifications, or using location services. These consume CPU cycles and memory, reducing what’s available for your video call.
Network Congestion: Poor or inconsistent internet connectivity forces the app to buffer or retransmit data, increasing strain on the processor. This can trigger stuttering video or a frozen interface as the system struggles to keep up.
“Modern video conferencing is one of the most resource-intensive tasks a tablet performs. Without proper optimization, even capable devices can falter.” — Dr. Lena Torres, Mobile Systems Engineer at TechInsight Labs
Essential Software Fixes to Prevent Freezing
Before considering hardware upgrades or replacing your device, explore software-based solutions. Many freezing issues resolve with simple adjustments that enhance efficiency and reduce system strain.
1. Update Your Operating System
Manufacturers release OS updates to address known bugs, improve multitasking, and boost overall responsiveness. An outdated OS may lack critical patches that stabilize video call performance.
- On Android: Go to Settings > System > System Update
- On iPadOS: Navigate to Settings > General > Software Update
If an update is available, install it immediately—preferably over Wi-Fi to avoid data charges.
2. Keep Video Calling Apps Updated
Developers frequently push updates to fix glitches specific to certain devices or OS versions. An outdated Zoom or Teams app may not handle newer codecs efficiently, leading to higher CPU usage.
3. Clear App Cache and Data
Over time, apps accumulate temporary files that can corrupt or slow performance. Clearing the cache resets this clutter without deleting account information.
- Go to Settings > Apps
- Select your video calling app (e.g., Zoom)
- Tap Storage > Clear Cache
- For persistent issues, tap Clear Data (note: this logs you out)
4. Disable Battery Optimization for Video Apps
Some tablets aggressively limit background activity to save power. This can throttle video apps during calls, causing freezes.
- Android: Settings > Apps > [App Name] > Battery > Unrestricted
- iPadOS: Battery optimization is less intrusive, but disable Low Power Mode during calls
Optimization Checklist for Smooth Video Calls
Use this checklist before important meetings to minimize the risk of freezing:
✅ Pre-Call Optimization Checklist
- ✔ Ensure OS and all apps are updated
- ✔ Restart the tablet to clear memory
- ✔ Close unused apps running in the background
- ✔ Connect to a stable Wi-Fi network (avoid public hotspots)
- ✔ Lower video quality in app settings if freezing persists
- ✔ Disable unnecessary widgets or live wallpapers
- ✔ Turn off Bluetooth and GPS if not needed
Real-World Example: Resolving Chronic Freezing on a Mid-Range Tablet
Sarah, a freelance graphic designer, relied on her three-year-old Android tablet for daily client calls. Over several weeks, she noticed increasing lag and frequent freezes during Zoom sessions. Initially, she assumed the device was too old. But after testing on a colleague’s newer model with similar specs—and experiencing no issues—she realized the problem was likely software-related.
She began troubleshooting systematically:
- First, she checked for system updates and found a pending OS patch from six months prior. After installing it, general responsiveness improved.
- Next, she cleared the cache for Zoom and Meet, freeing over 300MB of stored data.
- She disabled battery optimization for both apps and restarted the tablet.
The difference was immediate. Her next call ran smoothly with no freezing. A follow-up test in low-light conditions—where processing demands are higher—also succeeded. Sarah concluded that neglecting routine updates and allowing background clutter had degraded performance over time, not the tablet’s age.
When Updates Aren’t Enough: Advanced Troubleshooting
Sometimes, standard fixes don’t resolve the issue. In such cases, deeper interventions may be necessary.
Reset App Preferences
This restores default settings for all apps without deleting data. It can fix permission conflicts or misbehaving services.
- Android: Settings > Apps > Reset App Preferences
- iPadOS: No direct equivalent, but reinstalling apps often has a similar effect
Reinstall the Video Calling App
A fresh installation removes corrupted files and resets configurations. Sign back in afterward to restore access.
Check for Malware or Bloatware
Some third-party apps, especially those downloaded outside official stores, can run hidden processes that degrade performance. Use built-in security tools or trusted antivirus apps to scan the device.
Factory Reset (Last Resort)
If freezing persists across multiple apps and updates, a factory reset can restore the tablet to optimal condition. Be sure to back up photos, documents, and login credentials first.
- Back up data to cloud or computer
- Go to Settings > System > Reset Options > Erase All Data
- Set up as new device and reinstall only essential apps
Do’s and Don’ts: Tablet Performance Best Practices
| Do | Don’t |
|---|---|
| Update your OS and apps monthly | Ignore update notifications |
| Restart your tablet weekly | Run 10+ apps simultaneously |
| Use Wi-Fi instead of mobile data for calls | Leave downloads running during meetings |
| Lower video resolution if freezing occurs | Install unknown apps from third-party sources |
Frequently Asked Questions
Why does my tablet freeze only during video calls and not other tasks?
Video calls require simultaneous use of the camera, microphone, display, network, and processor—making them among the most demanding operations. Tasks like browsing or reading e-books use fewer resources and are less likely to expose performance bottlenecks.
Can a virus cause my tablet to freeze during calls?
While rare, malware can run background processes that consume CPU and memory. If your tablet behaves erratically beyond freezing—such as showing ads, redirecting browsers, or draining battery quickly—a security scan is recommended.
Will clearing cache delete my call history or saved meetings?
No. Clearing cache only removes temporary files like thumbnails or session data. Your account details, meeting schedules, and chat history remain intact unless you choose “Clear Data,” which resets the app entirely.
Conclusion: Take Control of Your Tablet’s Performance
A tablet that freezes during video calls isn't necessarily obsolete—it may simply need attention. By staying proactive with updates, managing background activity, and optimizing settings, you can extend its useful life and maintain professional reliability. Technology evolves quickly, but thoughtful maintenance ensures your device keeps pace.
Start today: check for updates, clear app caches, and run through the optimization checklist before your next meeting. Small actions now prevent disruptions later. A smooth, freeze-free call reflects not just on your preparation—but on your commitment to seamless communication.
