• Outdated Physics Wallah app version
• Corrupted app cache files
• Low device RAM or storage space
• Server-side issues or maintenance
• Background apps consuming memory
• Video quality settings too high
• Battery optimization restrictions

Identifying the exact cause can help you fix the issue faster.

Fix Methods

1. Check Your Internet Connection

The most common reason for PW videos not playing is unstable internet speed.

• Switch between Wi-Fi and mobile data
• Restart your Wi-Fi router
• Move closer to the router for stronger signal
• Avoid large downloads while watching lectures

Stable internet is important for smooth video playback.

2. Restart the Physics Wallah App

Temporary app glitches may stop videos from loading correctly.

• Close the PW app completely
• Remove it from recent apps

This simple step often fixes loading and buffering issues.

3. Update the PW App

Older app versions may contain bugs affecting video playback.

• Open Google Play Store or Apple App Store

Updates usually improve app performance and fix playback errors.

4. Clear App Cache

Corrupted cache files can interfere with video loading.

For Android
