As has been mentioned, if you are looking for great pictures and a camera that's versatile in a number of situations, a cell phone's camera is probably not the best bet.
These are just some basic settings for those looking for some info:
White Balance: I'd usually leave this at auto. Having to manually change it each time you take a shot in a different setting can be a pain. Furthermore, if you happen to come across one of those photo opportunities where a second take isn't possible, it helps to save time by having it on auto. Besides, auto does a decent enough job.
Resolution: My default resolution when I bought the phone was under the 8MP number. Make sure you set it up for the highest resolution. While MPs usually don't mean much unless someone is printing, it is better to have it at the higher settings. Low resolution images on cell phone cameras suck.
ISO: ISO refers to the light sensitivity. Like white balance, it's ok to have it on auto for quick pictures. If you do have time to shoot then manually adjusting it is the way to go. The lower the ISO, the less 'noise' the picture will have. However, the lowest setting only performs best under good light. If it were dark and you had the setting at 100 for example, your camera's shutter speed would compensate by lengthening the time the shutter is open. This causes blur. In darker settings, the higher the number, the better. Since image stabilization is almost non-existent or sucks in these cameras, use higher numbers. Unless you are using a tripod of course.
Grid: I have it set to off, but if you are wondering what the function of this setting is, read about the 'rule of thirds'.
Auto focus: Again, depends on what you are shooting. Manual, touch focus is great for macro type shots and certain other applications, but seeing how the shutter button is on screen, errors can be made, thus changing the focus point. Auto works decently, but manually just ensures the subject you are capturing is in focus.
Photography is a culmination of a number of settings. (In-Camera) However, users need to always take into account their environment.
Composition is very important to creating a good photograph as well. (Rule of thirds will shed some light on this if you plan on looking it up)
As to one of the comments above, the reason cell phone cameras have very poor image quality is down to the lens AS WELL as the size of the sensor.
Hope this helps someone.
