Why isn't my iPhone 5 allowing me to take photos on camera or other apps?

I recently dropped it and it smashed but this happed a day or so afterwards, the phone won't take photos on anything and I have enough storage so I don't understand? The camera won't turn around or anything so I don't know what's going on can anbody help me?

I'd take it to an Apple Store but if anything try a reset or restart 1st.

  • Why is my iPhone 4S not allowing me to FaceTime or iMessage? I have about five people who have an iPhone on my contacts. My phone will not let me send and iMessage or FaceTime them! What's wrong with it? I'm getting annoyed because I have FaceTimed and iMessaged last week and both stoped working Saturday. The only thing my phone sends are text messages. Can anyone explain why?
  • Why does some of the photos that I take with my iPhone 6 so much bigger than the other photos? I didn't change any of the settings in my phone as I have been taking one photo after the other. I don't think it is a burst shot either because I do not hold the capture button for long. So I'm expecting all photos to be relatively the same. Some photos even reached 200MB! I'm puzzled atm…
  • Recently my iPhone stopped allowing me keep YouTube sound playing in the background? I used to be able to exit YouTube and pull up my utilities page and hit play and now the YouTube video disappearing. Is this just a new way to force you into getting YouTube red?
  • My iPhone 4 is not allowing me to send text messages? I'm able to send and receive txt messages perfectly within USA I have AT&T as my wireless carrier.
