Video calls have become a cornerstone of modern communication—whether for remote work, staying in touch with family, or attending virtual classes. But nothing disrupts the flow like a frozen screen on your tablet mid-conversation. The frustration is real: you're trying to share an idea, confirm plans, or simply be present, only for your device to lock up, stutter, or crash entirely. While tablets are powerful, they aren’t immune to performance bottlenecks, especially under the strain of real-time video processing.
The root causes of freezing during video calls vary widely—from outdated software to insufficient memory and overheating. The good news is that most of these issues can be addressed through smart settings adjustments and routine maintenance. Understanding the technical demands of video calling apps and how your tablet manages them empowers you to take control of its performance.
Why Tablets Freeze During Video Calls
Tablets, even high-end models, have limited hardware resources compared to desktop computers. Video conferencing apps like Zoom, Google Meet, and Microsoft Teams require significant processing power, memory (RAM), and stable internet connectivity. When one or more of these components fall short, freezing becomes likely.
One primary reason is CPU overload. Encoding and decoding video in real time consumes substantial processing power. If your tablet is simultaneously running background apps, syncing data, or managing system updates, the processor may struggle to keep up. This leads to lag, frame drops, and eventually, complete freezes.
Another common culprit is insufficient RAM. Modern video call platforms use between 300MB and 800MB of memory per session. If your tablet has only 2GB or 3GB of RAM and multiple apps are open, the system may begin swapping data to slower storage, drastically reducing responsiveness.
Storage also plays a role. A nearly full internal drive can slow down app launches and system operations. When free space drops below 10%, Android and iOS systems often throttle background processes to preserve functionality, which ironically harms performance during demanding tasks like video calls.
Key Settings That Impact Video Call Performance
Many users overlook the impact of simple settings changes. Adjusting just a few options can dramatically improve stability during video calls. These tweaks reduce the workload on your tablet’s hardware without sacrificing essential functionality.
Lower Video Resolution in App Settings
Most video conferencing apps default to HD (720p or higher) video transmission. While this looks great, it demands more bandwidth and processing. In low-light conditions or on older tablets, rendering high-resolution video can cause stutters. Reducing the outgoing video quality to 480p in the app’s settings menu significantly reduces strain.
Disable Unnecessary Features
Virtual backgrounds, filters, noise suppression, and augmented reality effects may seem harmless, but they rely on continuous image analysis and AI processing. On mid-range or older tablets, these features can push the CPU past its limits. Disabling them—even temporarily—can prevent crashes.
Adjust Display Refresh Rate
Some newer tablets support high refresh rates (90Hz or 120Hz). While smoother scrolling feels better, it increases GPU usage and battery drain. Switching to 60Hz during video calls conserves power and reduces system load, improving stability.
Manage Background App Refresh
iOS and Android allow apps to refresh content in the background. While useful, this constant activity eats up memory and CPU cycles. Turning off background refresh for non-essential apps ensures more resources are available for your video call.
“Optimizing app settings isn’t about compromising quality—it’s about matching capabilities to your device’s actual performance envelope.” — Dr. Lena Torres, Mobile Systems Engineer at TechInsight Labs
Step-by-Step Guide to Prevent Freezing
Follow this sequence before each important video call to minimize the risk of freezing:
- Reboot your tablet – Clears temporary files and stops rogue background processes.
- Close all unused apps – Swipe away apps from the recent apps list to free RAM.
- Check for system updates – Install pending OS or app updates that may include performance fixes.
- Switch to Wi-Fi if using cellular data – Wi-Fi typically offers more stable bandwidth for streaming video.
- Lower video quality in the app – Go to settings within Zoom, Teams, etc., and set resolution to 480p.
- Turn off camera effects – Disable virtual backgrounds, filters, and beautification modes.
- Reduce screen brightness – Lower brightness saves battery and reduces thermal load.
- Place the tablet in a well-ventilated area – Avoid soft surfaces like beds or couches that block vents.
This routine takes less than three minutes but can prevent hours of frustration. Think of it as a pre-flight checklist—small actions that ensure smooth operation.
Common Hardware and Environmental Factors
Beyond software, physical conditions contribute to freezing. Overheating is a major issue. Tablets generate heat during prolonged video use, especially when charging. Once internal temperatures rise, processors automatically throttle speed to prevent damage, leading to sluggish performance or app crashes.
Dust accumulation in charging ports or speaker grilles can insulate heat, worsening the problem. Similarly, using bulky cases while charging traps heat inside. Removing the case during long calls improves airflow.
Weak or unstable internet connections also trigger freezes. Even if your Wi-Fi signal appears strong, network congestion or interference from other devices can cause packet loss. This forces the video app to rebuffer constantly, increasing CPU usage and draining the battery faster.
| Issue | Symptom | Solution |
|---|---|---|
| Overheating | Device feels hot, screen lags, app crashes | Stop usage, remove case, cool in shade, avoid charging during calls |
| Low RAM | App switches slowly, freezes after a few minutes | Close background apps, restart device, limit multitasking |
| Poor Wi-Fi | Audio cuts out, video pixelates, connection drops | Move closer to router, switch to 5GHz band, restart modem |
| Outdated Software | Frequent crashes, compatibility errors | Update OS and apps regularly |
| Full Storage | Slow response, apps fail to launch | Delete unused apps/files, use cloud storage |
Mini Case Study: Sarah’s Work-from-Home Breakthrough
Sarah, a project manager based in Portland, relied on her 4-year-old iPad for daily team check-ins. She frequently experienced freezes during 30-minute meetings, forcing her to rejoin multiple times. Her colleagues began joking about her “disappearing act,” which undermined her professionalism.
After reading about tablet optimization, she took action. First, she rebooted her iPad and deleted several unused apps, freeing up 4GB of storage. Next, she disabled Memoji effects in FaceTime and turned off background app refresh for social media apps. She also moved her Wi-Fi router closer to her home office and switched to the 5GHz band.
The results were immediate. Her next meeting ran smoothly with no freezes. Over the following week, she tested different configurations and found that keeping screen brightness at 50% and avoiding charging during calls prevented overheating. Within days, her reliability improved—and so did her confidence.
