Parts of screen do not work after battery replacement.

After a battery replacement I noticed the following:

1.1)The y or 6 key is not working. I tried the phone on landscape orientation and I saw that the keys were working. Then I tried to draw something on an app, and I saw that in the same place I coudn't draw. As you can see in the following images

the touch is not working in this specific area, (like a vertical line).

1.2)The other thing I noticed is that in this area, some times there are two white lines. They are not there all the times, they appera and dissapear.

The first two are the main issues, and what bothers me more.

2.1)Some times the touch screen when I swipe on one side and want to change screen, doesn't go to the next screen, but to the screen after the next. (Eg let say I am in the main screen and want to go the secong on the right, it could go directly on the third)

2.2)In addition to the previous, sometimes, when I swipe, instead of swiping ,the phone functions like taping, and it enters an app.

Those two are not so important, but I add them just in case, to find out what is the main issue.
