It seems like it doesn't use the flash when it should, then when I turn on the flash the pictures are too bright. It just seems like all the pictures are fuzzy to me. Maybe I am being too picky.
A couple of tricks I employ:
1. Don't use the virtual shutter button on the phone's viewfinder screen to take your shots. Tapping on that will sometimes cause camera jiggle. Instead, go into your camera settings and set "Volume Key Function" to capture. Once you make that change, to take a picture you hold down the volume button and when you want to take the shot you release the volume rocker. This method allows you to use two hands to hold onto the phone, increasing stability and minimizing camera jiggle.
2. While framing the shot, using index finger of your free hand, tap the screen in the area where you want the camera to focus. Using this tip, in conjunction with tip #1, will give you clearer shots.
My sequence is this: Holding the camera in right hand with thumb on bottom edge, index finger positioned on volume rocker, middle and ring finger on top edge, I depress and hold down the volume rocker. Then I tap the screen with my left index finger on the area I want the camera to focus. Then I grip the phone with my left hand--index finger on top left corner, thumb on bottom left corner, for added stability. Then I release the volume rocker/shutter. After a while it becomes a natural movement.
As always, make sure your camera sensor window is clean.
