Just like any other camera, your camera phone will have its own quirks. You must take the time to get to know how to use it properly. Take note of how it behaves under different lighting conditions. Figure out how to hold it properly and how to shoot with it most effectively. Most camera phones that are made today don’t have manual controls for their exposure. They are always in “auto” mode, which means that your phone’s camera sensor (not you) will choose the best exposure settings according to the lighting conditions surrounding you. The only way to take control of this process is to think ahead and know what your camera is going to do before it does it. For instance, the photo below, from my iPhone 5, taken outdoors with good light was easy to take and produced a fairly sharp image; the sun was out and my phone had no trouble getting a good exposure. The shutter speed was very fast and produced no motion blur.
Focus on taking an interesting image. That’s what photography is about anyway. Camera phones operated with a touchscreen (smartphones) suffer from shutter lag — yes, even the fastest, smartest of smartphones will have a bit of lag. Shutter lag is the lag that happens between the time you press the shutter release and when the camera actually takes a photo.
