Lenovo K6 Note - Malfunctioning Touch, Screen Replacement Issues, & Phantom Touches Solution

Hello, in May my phone fell to the ground, as a result of which a spider web was created on the screen at first the touch was working but after some time the display and the touch fell. After sending it to the lenovo service, the repair was calculated at PLN 400 with a penny. I refused to repair on lenovo service and gave it to a friend for replacement with a replacement about PLN 150 display. After the translation, it was okay at first, but after a while the screen started to go crazy (spontaneous touches) after leaving the Screen Touch test overnight there were a lot of lines in the room where there was no movement (shakes etc.). Replaced Display was under warranty so I gave it for replacement (I thought it was a factory defect of the display that was installed) Unfortunately, when the new display came again it is the same phenomenon. Any ideas what you can do to reduce this phenomenon or get rid of it? greetings

If after the fall the display was whole and only the touch cracked and after a while the screen stopped displaying, in my opinion something more damaged.
Sometimes the battery is damaged and makes strange pranks, while the parts should be original and not replacements because it is their fault that the things described by you may happen.
Personally, I would not assume replacements and if the next one you ordered was the original, it is not a defect of either touch or display.

that is, the only thing left is to look for the original touch: C just where do you get it from now

You need to look for a phone with a damaged charging input or and reschedule electronics or with a damaged soft, or wait until parts get cheaper or sell them yourself as damaged.
