LCD not working after glass replacement?
I replace glass for the Galaxy S3 all the time, and I've been doing fine. I also have succeeded in replacing the glass on the Note 2 as well. However, I find some of Galaxy Note 2 LEDs don't work after a glass replacement—indicating I must have caused some damages to the LED.
I don't see any cracks, and I only apply 70 °C of heat to loosen the adhesive. And, I use the trusted iFixit spudger to remove it with the same method that I apply to the Galaxy S3—but I find that 3 out 10 times, I will have a problem with the display.
I know it is a risk as you are not supposed to remove the glass, but in order to provide price options, I do it anyway. But I can't keep doing this. Can anyone share what not to do?
