I've been using it since 2014 june, but after 2015 january my touch screen often behaves erratically at random moments. Suddenly it will start registering clicks that are not there. I can see the clicks being registered by dots on the screen that normally indicate where I touch the screen with my fingers. Those dots appear out of nothing, when I'm not touching the screen, and randomly menus are opened, programs closed, etc. It's incredibly annoying.
Does anyone know a solution to this? I never use touch screen because I use a wireless mouse and keyboard for this.
