Why did the bottom half of my screen stop working?
There is a thin crack barely noticeable though the middle and from the crack down, the phone doesn't respond to touch.
The Alcatel One Touch Idol 3 features a 5.5 inch, 1080 x 1920 display powered by a 1.5 GHz processor.
Your screen is a "packet" with many layers of tech, haha easy explained, the crack might be tiny, but if it is deep enough it will damage the digitizer or lcd, or just simply the whole thing, but as you refer for, is the touch defective. it is kinda self explaining i would think this answer?
I am sorry if this is a bad answer or really bad written but it is the best i could write in english, haha sorry.
Here is a little picture of how touch screen works:
