It only goes so far as necessary to swap out the front section of the phone to fix a broken screen.
I'm opting to fix this myself altho the phone is covered by insurance because the insurance deductible is $100 and the spare part on eBay is only $50.
If I wanted to be even cheaper, I could just cover the screen in a piece of clear packaging tape and continue using it indefinitely. The functionality of the phone is still intact.
Step 1: The problem
It's still operational, but sharper than it was.
The positive take -- it's a good excuse to do surgery on my new(ish) phone!
Step 2: Tools
They both include very tiny screwdriver heads for very fine work. I've never run into anything that was too small to use these on.
When you first buy them, try rubbing a neo magnet on the tips to make the screws stay on against gravity. It doesn't take much magnetism to make your work a lot easier.
Step 3: Remove back cover
Just slide the back cover up with your palm and then lift it straight off.
Step 5: Remove four torx screws
HINT: If you're very disorganized or you're planning on leaving the thing apart for several days, immediately put the screws back in the holes they came from after you separate the parts. It's a little bit of extra work, but it'll keep the tiny screws from getting mixed up or lost on the floor. This is a good rule of thumb whenever you're taking stuff apart.
