my screen has color lines all over the screen how do i fix it , do i change the digitizer or the lcd when i take pictures or screenshots it looks good.

Because your screen is cracked, it is interfering with the display. I do not know if you screen (digitizer) is fuzed with the display (screen). You will need a replacement of both. If I where you, I would go to eBay and buy the parts with the best reveiws. I cannot aid with the actual replacement, but I suggest looking on YouTube for a tutorial and looking at other devices screen replacement guides to give you an idea. Hope this helps!
