How much of your phone's capabilities do you use?

This is geared more towards high end Android users. I'm sure iPhone users utilize 100% of their phones capabilities. But anyway, phones do so much more then take flicks, text, web browse, and make calls. I would say I use about 20% of what my phone (GS4) is capable of. I'm not super tech savvy so I'm kind of afraid I'll do some kind of irreparable damage if I try to unleash my phones full power but I take advantage of a lot of things it can do fresh out of the box. Also, I usually upgrade my phones once a year so I never have a phone long enough to truly see all that it can do. But the GS5 is kind of disappointing to me so I can comfortably say I will have my GS4 for a while.

What about you guys? Please add what phones you currently use as well.
