Earlier today my phone screen cracked up by the front camera, probably from the metal water bottle in my bag, and now the screen is black with a green and red line running down the right side. However, my phone still makes noises when I receive messages. Is my LCD broken or is there another issue? Wondering whether it is worth repairing or just getting a new phone

yes, your LCD is very likely damaged. the iphone six screen replacement is usually close to 1/4 the cost of the retail value of the phone. it is more sensible to get it repaired. doing it yourself is a more dangerous prospect, but also the least expensive
