Facebook app. It's very good. Easy to use. Easy to find stuff on. Easy to talk to your friends. Lots of reviews. Lots of people hack other people on there. Security could be better makes your phones go slower sometimes. And also the internet connections aren't that great so it keeps stopping every now and then but it might be my phone. Not quite sure could be your G4. I don't know but it is good. I enjoy it. Go on there a lot. Chat with my friends. Very good
