IPhone 7 is running extremely slow and will not play videos or audio output

I woke up to a dead phone this morning and it was giving me issues. Once I charged it and saw that I needed an update I decided to update it in hopes of fixing my phone. The update did no help and my phone still won't play videos, sound, and is very slow. What should I do?

Id do factory reset cause it can fix those issues

I'd try a reset of the phone, through iTunes.

  • Why is Sprint 3G Extremely Slow On Iphone 5? When I'm on 3G, no matter what internet connection does not work, going on the AppStore doesn't work, just to wait for a game to load it doesn't work! Like wtf? I'm truly lucky to have Wi-Fi, cause If I didn't I would lose it, but once I get off Wi-Fi, it's SLOW SERVICE! Sprint bills aren't cheap either, I have 2 iPhones on the same plan, what should I do please?
  • Official ios7 on iphone 5 typing extremely slow why? I just finished updating my iphone 5 to ios 7 today 9/18/13. And the typing is extremely laggy and barely can make out words
  • My Iphone 4s only plays audio when I try to play videos? I have downloaded many different video players through cydia including VLC and all i get is audio. I also converted the files to almost every file type and got the same. WHY IS THIS HAPPENING! I'm so frustrated that I left android to try out an iphone and this is what I get. Any help would be very appreciated.
  • Is iTunes and Everything Else Apple Running Really Slow for Everyone? I'm trying to download ios7 but did not have enough space on my iPhone. So I did a full system restore and am trying to restore the iphone now, but itunes will not connect to the store and I can't restore from wi-fi either. EDIT: I'm also trying to install iTunes 11 to see if that will solve the issue, but the setup.exe file has taken over 20 minutes to download as well.
