I have an iphone 5 and noticed my celluar data slightly increases when I use Wi-Fi. Why does it do this and how can I prevent it?

Dropped my iphone 4s in water?

Should I worry? I was washing my hands and I was out of it because I just woke up. I set my phone down on the edge and the next thing I know it slides down into the sink.

I immediately take it out and dry the water with a nearby towel. I see if everything is ok and it is working normally. Should i worry? Everything from camera to sound is fine.

I got nothing for Christmas?

I know what you guys are thinking right now, I'm a selfish little brat; but I got absolutely nothing for Christmas. I'm a straight a student, I help out in the soup kitchen all the time and I'm from a middle class family. I wouldn't have a problem with it but my brothers both got a trip to the UK and a iPhone 5. You know what was under the tree for me, nothing. It hurts because it's a tradition that we open our gifts on Xmas eve and we all get something, I even asked my parents what I got but they said "Don't bother asking" I only got a book last christmas too and barely anything during the year (food, and 3 t-shirts) I know christmas Is about giving and love but none of that was shown to me.

My iPhone 5s camera is acting weird?

When I take a picture I've realised that the camera flips my photo I. E if there's something on my tshirt thats on the right it will move to the left. How can I stop this from happening?

Am I just not photogenic or am I just not attractive?

It's weird because I look fine when I look in the mirror and I often get compliments about my appearance but when I look at myself in a picture, I look awful! I look normal on iPhone pictures but when I look at a picture of myself on a normal digital camera, I just rather not even take pictures to begin with. I get really insecure about myself because of it. Are some people just not photogenic?

Gopro won't turn on, charge, or connect to computer?

I just got a gopro for christmas and can't use it.first i tried charging it in a iphone charger and after a couple tries the red light came on after an hour i went and turned the power button on and the red light turned on and nothing happened. So i went to the computer plugged it in and it didn't say anything was connected and it won't turn on.

My iPhone won't make any sound except when it rings?

I was watching YouTube videos on my phone and then all of a sudden the sound disappeared. I turned my volume all the way up. I even tried playing music but no sound. I called my cell to see if it would make a sound when it rings and it does ring but the sound of my keyboard clicks won't make a sound either. I went to my settings to see if anything is off but it's not. How do I fix this?
