Don’t be afraid to change your cracked iPhone screen yourself. Here are some caveats before you do.
You can get the screen for pretty cheap. Just about $20. What you do NOT want, is to get just the glass. Replacing just the glass is way more difficult. The LCD and the touch digitizer is glued onto the glass, so removed those pieces and gluing them back onto the new one is extremely difficult and not worth the $10 in savings.
Don’t freak out if your new screen and old one don’t look exactly alike. The left is my phone. The right is the screen replacement. There’s a piece rubber that needs to be removed. They’re the same screen.
Consider getting a magnetic mat. I didn’t have one when I replaced mine, but fI can see the value. A couple of alternatives to doing this is to create your own place where you’re putting your screws, like using some double-sided tape on the table or packing tape, upside down, so that you can stick your screws to it. I used a white bowl, where I put a magnet inside. I have a little spinning toy that’s stuck to my fridge that I took off. I used the different spaces at the edge of the toy as a divider and put the screws in order so that I would put them back in the same order. Here’s a picture:
Consider getting some spare screws. They are very easy to lose. They only cost about $2.
You might need another metal shield plate. I broke mine. The ribbon is glued onto the glass screen and I just yanked it off with the tweezers. Be careful and you might not need it, but know that if you do break it, it’s only $4. I’ve circled where I broke it.
Here’s a nice video that shows the process:
