the screen defect is not related to this at all
the screen defect is caused by the circuit behind the screen not being able to provide equal power to all parts of the screen, it has nothing to do with the glass
now this is rarely an issue on LCDs, but amoleds consists of numerous of oleds per pixel, so each of them is powered and signaled through some sort of controls, some of these oleds dont get enough currents, which is why this issue exists
Please forgive me, what is the defect that you are referring to?
I thought we were talking about cracks....
Some people have referenced the fact that some point of the manufacturing process might be causing initial cracks that grow over time with additional temperature change.
edit: I might have read you wrong...you might be referring that the hairline cracks are not created during user use. I'd agree with that. Most electronics can survive what humans can't. Although a crack could grow like on a car window after the initial damage.
Sorry for resurrecting this topic.
Newbie here. I have the same issue my T989 was 3 month old then while holding it the LCD totally cracked inside and can't be use anymore. I never dropped it or done anything harsh to it's LCD. I'm just holding it then when I was going to check the time. Boom! LCD is totally gone! Only the top part is visible.
