Screen display is acting it self

@virukori what you are experiencing is called "Ghost Touching" and is caused by an issue with you digitizer. To fix that, you will need to replace the complete display assembly, which includes the digitizer.

Since iFixit does not yet have a guide for this, use something like this video. Replacement screens are readily available at many online stores.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
