amaanmehdiThe only way I can think off is hard pressing on screen while it's warm/hot, which is unlikely in many cases, therefore only thing left would be defective phone. You are doing the right thing by taking it to a Service Centre though and we wish you good luck.
My phone screen just cracked from the inside, all of a sudden. I was using it normally until I went for dinner - I locked the screen, kept it away. Upon returning and trying to unlock the phone, the screen went half black and weird colors were showing up and the touchscreen wasn't working at all. The phone has never been dropped and it's been just 3.5 months since purchase. The outer gorilla glass is completely fine, only the inside is cracked at the edge.
I searched around and found this: https://zentalk.asus.com/en/discussion/16751/rog-phone-2-display-broke-inside-with-no-physical-damag...
My question is, how is this even possible? How can the phone screen break (and from the inside!) without any rough handling? I even googled and found that there are many users who are having (or had) this issue. Were some phones defective? Or is there some design flaw?
P.S. I am really sad. I just paid up my final EMI for this phone yesterday morning and was so happy and today it broke :(. I will be taking this to the service center tomorrow and hopefully, ASUS will not disappoint me.
Phone screen broke from inside, no falls, no rough handling!
