Also do u not know how to cange ur profile pic?
It's simple if u want a picture u like just go to the settings below ur words(not the settings next to gallery and share) then click it. It will bring up all of ur info and u scroll down to change profile? -i think that's what it's called- away click that and click ur picture. It will come up with ur photos. click the lastest one u picked then click done. And boom u have a profile pic

Ok I will tell you

How?
