This might only happen to people who travel through various climates, but I had my keypad start popping up and now it's like a bubble once the MSM8909 warms the underside of the board. It's due to expansion and contraction, but now I need to get a donor L125DL's bottom half before I can pick up where I left off. I'll be back, but right now I'm in a tight spot and it will be at least January before I can get a new keypad membrane or another L125DL...
I've traveled from US, to Indonesia, to Japan, and to various parts of those countries. My phone has seen so many climates and has quite the story to tell but I don't want a $15 part to be the reason that I can't keep using it.
