Why is my iphone 5 sending blurry videos?

I used to be able to upload videos to facebook… Now it doesn't work! Also when i take a video its clear. But if i send it in an iMessage or text its super blurry… Please if someone can help… At&t said they never heard of it. And best buy won't help either unless you have insurance on the phone.

Ok, your videos are blurry because you still have a lens protector on. Remove this, a d also refrain from touching the lens with your fingers
