[Q] part of touchscreen not responding

I've had my Nexus 4 for about 2.5 years now and a few days ago, part of the touchscreen stopped responding to presses. It also goes erratic at these spots, but only when the phone gets warm. It then becomes completely unusable because it keeps pressing things within these unresponsive areas, like shown on this screenshot (dots on top are random automatic button presses within the unresponsive screen area):

It is definitely hardware related, but i have no idea what caused this. It happened from one day to the other.
Any ideas how i can get these unresponsive areas on the screen back to work? I wanted to keep this phone for at least 3 years..

Help with ghost touch!

I have a Lenovo Vibe K4 Note. Its been more than a year since I bought it. Some day before it started to develop white spots on the border of the screen. It expanded and covered the whole upper half of the border of the screen(only the border). Then in the white spot there started to appear silver shiny thing which appeared to be like a foil or something. But this didn't got any serious problem until my screen started malfunctioning. Suddenly when I was handling the phone it started touching here and there in the upper half of the screen automatically. Its been 2 days I am having this problem and at this second the situation is that I can't even unlock my device properly l because when I go to enter the pin it automatically start typing. It's not two or three touches but its way much faster auto touch. About 6-7 touches every second are happening. I need help. Is it software problem or a hardware problem? How can I solve this?. BTW it is working on Android 6.0 (ROW S232). Any help would be greatly appreciated.
