To capture great Fourth of July fireworks photos with your phone, stabilize it, turn off the flash, and use night mode or HDR. Lock focus and consider using burst mode or recording video. Don't zoom digitally, as it degrades image quality. 

Here's a more detailed breakdown:

Pre-Fireworks Preparation:

Stabilize Your Phone:

Use a tripod, phone holder, or a stable surface (car, cooler, etc.) to prevent blurry shots.

Turn Off Flash:

The flash won't reach the fireworks and can cause unwanted light reflections. 

Enable Night Mode or HDR:

These modes are designed for low-light conditions and can enhance the fireworks colors and details. 

Lock Focus:

Tap and hold the screen during a bright flash to lock focus and prevent the camera from refocusing on smoke or other distractions. 

Consider Burst Mode:

Capture multiple photos per second by holding down the shutter button, increasing your chances of getting the perfect shot. 

While Shooting:

Don't Zoom:

Digital zoom degrades image quality. Instead, move closer or use the wide-angle lens if available. 

Consider Recording Video:

Record the fireworks in 4K video and then extract still frames afterward for more flexibility. 

Experiment with Settings:

Try different shooting modes and techniques to see what works best for your phone and the specific fireworks display. 

Additional Tips:

ISO:

If your phone allows manual settings, try a lower ISO value (around 800 or lower) to minimize noise in the image. 

Accessibility Settings:

If your phone has a "dim flashing lights" setting, disable it, as it can interfere with capturing the full brightness of the fireworks.
