How to take great pictures with a smartphone?

Nowadays our smartphones have more computer power than a 10 years old desktop computer. Technology is evolving fast and with it, the language acquiring new words like smartphone or selfie.

We are doing everything with our phone, from a GPS assistant to photograph or record a movie in full 1080p HD, even post processing those images, and i don't even speak about playing 3D games, read some news on internet and so on...

At the end, when we compare how we use our phone the most, in percentage, I can say safely that we barely use it to call someone, and this is why i call mine a photophone.
