Poketbook 623 touch screen problem
Hello everyone. I have a problem with my PocketBook 623 and it's touch screen, in most cases, it doesn't work or if I press it starts to draw random lines ( I have checked it in notepad). After some minutes touch works for a while and then it is broken again. I can't use pocketbook reader because everytime I open book, it starts zooming in and out.
Any suggestions? I changed soft from 4.4 to 4.3 . Previous owner had the same problem.
