I'm having problems with my iPhone 5s?

I just got my iPhone 5s two weeks ago, and it closes out of apps by it's self while I'm using the apps. I know how to force close the apps, and that's what I do whenever I'm not using the app. And it doesn't connect to Wi-Fi. I have to reset the router for the Wi-Fi to work. And it's really annoying. Whenever I try to connect, it says "Unable to connect to Wi-Fi". And I'm putting in the right password. I know I'm.
Is there a way to fix this? Or should I take it in and have it replaced?

  • Why is my IPhone 3GS having problems after I updated it? After updating my iphone to the latest version (5.0.1I think it was) my phone just randomly started shutting off and coming to a blank white screen and then an error screen and after a few times it went back to normal then shut off again. Right now it is recovery mode and not working so I was wondering if anyone has the same problem and a solution to it.
  • My iPhone is having many problems, it keeps freezing and touching the wrong keys My iPhone is freezing every second when I'm using it. Like the keyboard keys freeze when I'm typing. Always sometimes when I click an icon on my home screen it likes the button next to it! Anyone know any solutions without getting a new one! I have also tried powering it off and on didn't work!
  • My iPhone 4 having problems with audio when video taping? Ok so I have had this phone for 2 months now and it's just now having this issue. When I record sound and other things it's fine except when I record video on my phone this sound is barely audible. I mean you still hear it but barely. Also anything else where sound around me and my voice I can hear it fine. So what's wrong with it and what should I do about it?
  • Is anyone having data problems with their iPhone 4? (Virgin mobile)? About 24 hours I started receiving an error message on my phone saying I'm not subscribed to any cellular data. I can text/call perfectly fine; however, my 3G is basically useless. I've called virgin mobile at least 10 times and none of them are willing to help. They just keep transferring my call. So does anyone know what's going on?
