IPhone freezing on Internet?

I have the iPhone 5c just last night it started freezing up on the Internet I must have had to shut it off about 2 or 3 times to get it to work it's making me mad I wanted an iPhone so bad because I was the only one who didn't have one. I have 156 songs 34 photos no videos. I Facebook messenger Twitter Instagram and Netflix. I was on Facebook last night it froze up about 3 or 4 times and I had to shut my phone off because the app wouldn't close. Same thing here on the safari I had to either refresh it or close the app because when I went to ask a question on here it would freeze. I downloaded the iOS 8 on Thursday but it just started freezing up last night. It's really pissing me off I have great internet connection I have dropped my phone only once that was months ago. I've had it since March. It's my first iPhone. What's wrong with it? Why does it keep freezing up on here or on Facebook? How can I fix it?

You can try resetting the iphone to factory settings, but before you do that you can back up all your data from you phone using itunes.

Tip for next time you get a phone: avoid iphones, they have problems like that, i know because one of my friends iphone does the same thing. Not criticising or anything, just trying to say you don't have to go with the crowd to be 'cool'. Getting for example a Samsung S5 would be a lot better choice in my opinion, here are some advantages, better rear camera (16mp vs. Iphones 8mp) which allows to record UHD (4K) video, better 2.1mp selfie camera, bigger screen, SUPER AMOLED display, which is brighter, has more vibrant colors and deeper blacks, and also more pixels making it more friendly to the eye and saves a lot of battery, water & dustproof, more ram (good for multitasking and having multiple apps open), more battery life which can also be replaced in case you run out.

Restore the firmware and set it up as a new phone.
