On 04.03.2016 my Zenfone started to behave abnormally. First, the camera app displayed vertical lines that tended to cover the whole screen. Then, the lines started to show even on the bootscreen and then on the All apps menu. I also notice some flickering.
I've reset the phone to factory settings, wiped the cache partition, reinstalled previous versions of the firmware, but there was no improvement. I've already tried the developer options fixes, but they didn't work.
The phone is not rooted. I didn't drop it or spilled liquids over it. All was fine until it suddenly went nuts.
To have some limited use, now I have to "manually refresh" the screen by dragging the upper drawer (this apparently still works).
After some usage, it gets better to the point of not showing any symptoms. Then after a period of inactivity the screen resumes acting weirdly.

I made a video here: https://www.youtube.com/watch?v=kRuxTefNcKw
I'll send it to service, but seeing others with the same problem I don't have much hope.

Is it a hardware or a software issue? Does it have a fix? Or the fix is: my money back, looking for other phones and avoiding Asus products.

service did not want to answer the reason for the failure. It will be a general failure? it will happen?

Can you please tell me that the replaced screen is still Corning Gorilla Glass 3? I read someone say that they don't give you Corning Gorilla Glass 3 next time, if you replace your screen.

Perhaps, those lines coming even in the recovery and bootloader is an indication that its not a software issue. The touch panel failed. Having this problem for quite a while now.
