Stephanie's cell phone stopped working because her college ID card got pushed between the sliding halves of her phone and cut the tiny ribbon cable that connected the top and bottom. Apparently purses can be treacherous places.
I was lucky to find a replacement cable online and ordered it. It arrived and when I got around to installing it, it worked beautifully.
We won't talk about the 27 tiny screws in four different sizes and the two pairs of reading glasses I wore working directly under a desk lamp to get it done. Who knew there were so many layers in a phone?
