without this suction cup clamp thing, removing (and replacing) the screen was the hardest part of this job. Especially when the screen is cracked badly as the suction cup loses suction due to air leaking through the cracks. In this case, use tape over the screen to create a smooth surface. ***Also, the screens have rubber running along the side, so use a heat gun or hair dryer to make the rubber softer for removal of cracked screen and installation of replacement screen

Hardest part was definitely removing/inserting the screen. These bastards are tight(which is good) took me a while to get it off, especially with the cracks being around the home button. takes patience and effort, but I did find that being a little more forceful and less careful than i thought i had to be was more effective. Removing the components from the old screen and attaching them to the new one was pretty straight forward, Just be careful with all the contact points and ribbons. However the Apple screen has a little clear plastic circle that frames the front camera that the iFixit screen did not have. I used it on the new one, but it was never fully secured and still had to be sure to realign the front camera several times. Putting the new screen in proved challenging. The directions made it seem far easier, and for a while I didnt think it was going to fit (it eventually did). Now just going to wait to make sure everything continues to work properly. Overall, defintly worth it
