Smartphone top tips 
1. Use airplane mode: Avoid interruptions from calls, messages, or alerts during filming.
2. Battery: Start with a full battery and carry a portable battery pack for extended shooting sessions.
3. Storage: Ensure you have enough memory space since videos consume a significant amount of storage.
4. Focus: Tap 'lock your focus' on the screen to maintain focus on the desired subject.
5. Stability: Use both hands, a selfie stick, or a portable tripod to keep your shots steady and smooth.
6. Zoom: Instead of using digital zoom, physically move closer to the subject for better video quality.
7. Sound: Enhance audio quality by getting closer to the sound source or using smartphone headphones as a makeshift microphone.
8. Light: Choose well-lit locations for filming to improve the overall video quality.
9. Clean your lens: Keep your lens clean using a lint-free cloth to avoid unwanted marks or smudges on your videos.
