Why won't my iphone play GIF's/Videos right?

I own an iPhone 4s and recently updated to iOS 7, however, although in good condition and memory space; it won't play videos correctly (laggy) on 9gag, vine, YouTube etc. The only place it will work is safari for some reason. I have tried re-downloading the apps and it makes no sense because I've had it in worse conditions when it had iOS 6, yet it worked fine.

Can my iphone 5s be hacked by text?

Received a text with:

It had my name and phone number in there too?

Any ideas what on earth this is?

Much appreciated!

Cracks on my iPhone disappeared then reappeared in a different place?

So I dropped my phone ages ago like in February and there's one long crack the centre of it and I dropped it again 2 weeks ago and there's a crack at the top (not on the screen) and a few days after I dropped it the second time these tiny cracks (that look like a tree with lots and lots of branches) appeared on my screen right above the first crack I made in February but that somehow disappeared and now today it's reappeared (I didn't drop my phone) but this time below the crack line and it's bigger, it's like tiny branches all connected to each other. It makes me feel funny seeing all these little lines connected but I'm also really freaked out, what's happening?

What is so attractive about The mainstream, about popular about The majority?

Why is everybody so into being in the mass.

Coca Cola
Starbucks
Mcdonalds
Iphones
Androids
Pop music (Miley Cyrus, Carly rae jepsen)
Pop movies (Transformers, Adam Sandler comedies)
Pop books (Hunger games, 50 shades)
franchise stores
etc…

Why does everybody conform.
It's almost like an instinct.
An instinct to conform.

I like Starbucks, but I don't like Starbucks because of it's popularity, I like Starbucks because I tried their products and I enjoyed it, but then again I don't see that as my only choice, there are many other cafes

IPhone 4S blocks when changing camera stance?

My iPhone blocks when I try to change the camera from back camera to front camera. It started doing so a couple of days ago for an unknown reason. It still reacts normally otherwise, like if I double tap the home key I can terminate the camera process but when I restart it it stays the same.

Why isn't my charger working?

I just got an iPhone 5c yesterday. I'm using the charger that it came with and it was working earlier except my phone would go crazy while it was plugged into the charger. Now when I plug it in it does not charge and the phone says the charger in not reliable. I can't use another charger because I'm not at home right now. Also the earbuds used to work but now music does not go through them. What should I do?!
