Back side iphone camera sound doesent work?

I went to a concert recently and took a bunch of videos off my iphone and when i whacthed them they had no sound at all. I realized that the camera on the back side of my phone sound doesent work but the front facing one does have sound. All the sounds work fine off my phone but only when i take videos from the back camera it doesent have sound. If i download those videos on my laptop, will they have sound?

What password is this referring to?

I recently got a new iPhone. I backed up my old iPhone to my computer when my new phone said to connect to iTunes when I pressed restore from iTunes. Then, I hooked up my new phone to my computer and clicked,"Restore Backup." It asked me to choose a backup to restore, then I clicked my old phone, and it says to enter your password! I don't have a clue as to what "password" it's referring to, and I tried my computer user password, my old phone's lock screen password and my Apple ID password, but to no avail.

Does staring at an iPhone screen at night (or in poor lighting) damage your eyes?

So I have really bad nearsightedness (a fairly strong prescription, kind of thick glasses & I'm only 18) :( and before I go to sleep I have a habit of surfing the web & checking stuff on my iPhone, and when I'm doing this no other light is turned on besides the light from the iPhone screen itself. Will this further worsen my vision (nearsightedness) or is it just a myth? Should I try not to do this during the night? I need REAL answers… Thanks…

How to sneak my iPhone 5S to school?

Okay so my school doesn't allow us to bring phones but I need mine because I'm about to start having these dumb after school activities so I have to stay at school until like around 5pm or later, it all depends. But I'm not 16 yet so I can't drive legally so I'm going to have to call my parents to come pick me up, and I honestly hate using the school phone at the office because it's confusing to operate and I usually have to have someone come work it for me because you have to type all these numbers before dialing the number youre calling. But since it's after school the office doors will be locked up. My school also does checks for things like that and they have those little stick/wand metal detectors and they make you take your shoes off and they check the backpacks and i don't know what to do. (I live too far away from my school for my parents to come drop my phone off so they won't do it)

Does an iphone 5 work on a prepaid card?

I was wondering if an iphone 5 will work on a prepaid phone card from either verizon or at&t. I have always used prepaid cards but only on phones that only use them. I know that you can use prepaids on galaxies and some others.
