🔍 Root Cause Possibilities:

1. WhatsApp permissions or bug


2. Wi-Fi sleep/power saving settings


3. Tablet’s software or firmware glitch


4. Conflict with Wi-Fi Calling or VoIP settings


5. Network hardware (router) issue during high-demand traffic like video calls

✅ Step-by-Step Fixes


---

✅ 1. Check App Permissions

Ensure WhatsApp has full access to network-related permissions:

Go to Settings → Apps → WhatsApp

Tap Permissions and Allow for:

Camera

Microphone

Nearby devices

Battery Usage → Set to “Unrestricted” or “Not optimized”




---

✅ 2. Turn Off Battery & Network Optimizations

Samsung's One UI sometimes puts apps or Wi-Fi to sleep.

Settings → Battery → Background usage limits

Disable Put unused apps to sleep

Add WhatsApp to Never sleeping apps


Settings → Wi-Fi → Tap the ⚙ next to your Wi-Fi network

Turn off “Turn off Wi-Fi automatically”

Disable MAC randomization if enabled




---

✅ 3. Turn Off Wi-Fi Power Saving Mode

Samsung tablets have Wi-Fi power-saving features that can interfere with video calls.

Settings → Connections → Wi-Fi

Tap the 3-dot menu → Advanced

Disable “Wi-Fi power saving mode” if it's on




---

✅ 4. Check Router Settings (if possible)

Some routers have aggressive QoS (Quality of Service) or frequency switching between 2.4GHz and 5GHz that can drop the connection during VoIP:

Try setting your Wi-Fi to either 2.4GHz or 5GHz only (not both) to prevent switching mid-call

Ensure WPA2/WPA3 security, not outdated WEP



---

✅ 5. Reinstall WhatsApp

There might be a corrupt install or glitch:

Uninstall WhatsApp

Reboot your tablet

Reinstall from the Google Play Store



---

✅ 6. Update Everything

Make sure:

WhatsApp is the latest version

Your tablet’s software is up to date:

Settings → Software Update → Download and Install




---

✅ 7. Clear Network Settings (Non-Destructive)

Settings → General Management → Reset → Reset Network Settings

This will reset Wi-Fi, Bluetooth, and mobile settings but won’t erase your data




---

🧪 Optional Test

Try using WhatsApp Web from a browser on the tablet (if it supports camera).

Does it still drop Wi-Fi during calls?

If yes, it’s likely a system-level or hardware issue.




---

🛠 If None of That Works:

1. Backup and factory reset the tablet (last resort).


2. Visit a Samsung Service Center to check for a Wi-Fi chip issue or known bug.


3. Report the bug to Samsung via the Samsung Members app → Get Help → Error Reports
