If you find that your shots are coming out a little blurry, try these tips.
- 
Hold the phone so that your fingers aren't blocking the camera lenses and flash. 
- Make sure that the camera lenses and flash are clean and without fingerprints.  Use a soft, clean, microfiber cloth to wipe them. 
- When taking a photo, adjust the focus on your subject by tapping it.
- Make sure you're not moving the camera when taking a photo, especially in low light conditions.
