What should I do with my iphone? - 2

So recently dropped my iphone with no case on and then I could see 2 white lines running through the screen and the touch screen doesn't work in that area and this morning another two line appeared and all of them run through the important apps and stuff and i can't press that area

There are many phone shops and kiosks that will replace broken screens. You can get the phone repaired much cheaper than replacing it.

Put a good case on it next time. I recommend the Otterbox Defender.

Sounds like dead pixels. Either way, if you're not planning on getting a new phone, you'll need to get it repaired.

Get it fixed.
