I'd like to say I was surprised when I shattered the iphone 5c lcd screen, but that screen had it coming. It had endured countless run-ins with sidewalks and tile floors and a few accidental acrobatic trips across the room. Finally, it was a 2-foot drop onto my driveway that did in the display.
Sure, you can fix your screen at home on your own. and all the tools you need to replace the screen at home on your own. Online, there's a step-by-step guide to handling the process and even a video to guide you.
Still, given the time it took me on my first go-round, I can safely say that gadget repair is not for everyone. If you can't dedicate a few calm hours to the process, or struggle working with small things, then you're probably better off taking your phone to a repair shop or the Apple Store and having them replace iphone replacement parts for you. You might pay a bit more, but you're guaranteed a product that's going to work.
