Phone drop causing future issues?

I recently dropped my phone (in a case, from not too high) onto the floor. It is fine, no physical damage or other issues. Camera, speaker, everything works fine. However, do I need to be worried about internal damage that could show up at a later date? In other words, can dropping a phone just once cause "delayed" damage?
