Iphone 4 camera stopped working?

So i dropped my phone pretty badly and my screen cracked. I don't know what happened, but after dropping it my back camera stopped working. Every time I try opening the camera app it stays on a closed shutter. The camera button and the button to switch from photo to video start to twitch. I just want to know a way to fix it, so my back camera can start working again. Thank you!

Added (1). Also my phone begins heating up on the camera every time I charge it or try to start the camera up. Another thing is i've tried downloading a separate camera app and it doesn't open on that either.

I can't sent or recive text message on iPhone?

So I accidentally turn off IMessage on my iPhone 4 and when I turn it on I can only recive from my email and I want to be able to sent & recive it off my number. But it doesn't let me. And it doesn't let me have an option to chose what to sent it from and it won't let my number do those. And it also says Waiting for Activation.

My iPhone won't notify me for text messages?

I have my ringer on. I have notifications on. I have banners, sounds, and vibrations on. The only way I'll know I'm getting texts is going to my home screen and checking to see if there are any red numbers on the iMessage icon. Or pulling down the top menu.

Dilemma about returning/ getting new iPhone?

So about 7 months ago I bought a legit new iPhone with my Verizon acct because I was due for an upgrade. No insurance on it. Two months later it got shattered which was my fault. I went on craigslist and bought a used phone that checked out fine. No damage, not stolen, works fine, no problems. Another legit transaction. Recently it is having some slight issues with dropping calls, not a big deal. I called Verizon tech support to trouble shoot it and they were just like " hey you are still under warranty so we're gonna send you a new phone". They do not have knowledge of the original phone being broken and this second phone is what I'm using. So when I receive and activate this new phone, and I'm *guessing* I have to return this current phone (that wasn't the original) … Can someone tell me what scenario I might expect? Will everything just go on as as usual or will they be like " Hey this isn't your original phone!". If the latter, will I be able to " get back" my used phone that I returned? Is this too confusing to understand?

Vine videos won't load on my iphone?

IPhone 5 payment on T-Mobile?

The T-Mobile simple choice plan says that it is $50 a month but then it says that unlimited 4g data is $21 a month and that the monthly payment is $20 monthly. Does this mean that I have to pay $91 per month? Please simplify this for me!

IPhone 4S charger has melted?

Okay so i have had my iPhone since october 2013 so it hasn't even been a year & between that time, i have bought a total of 6 chargers! At the end of the day, they either stop working unless i holddm phone in a certain position, or they start saying "the charger is not compatible with my device" my recent kn just melted. This is the first time it has happened. There's no problem with the adaptor but the usb part where i connect to the adaptor, just melted off for no reason! I can't call APPLE CARE because they keep telling me to pay to speak to a customer rep. So why do i do now? I really don't want to waste my money on a new charger for it to repeatedly get spoilt!
