Got this similar problem again...
Every time I open my communicator, the LCD screen of my 9210 will flicker with lines and some buttons on the side will not functionin' anymore. In order to solve this irritating problem, I should position the opening of my communicator interface to the tilt of 90 degrees or in such a way when the screen is not flickering anymore. This has happened already after 1 yr of using my 9110 then again it's happening now on my 9210 after 1 yr of using too.
Maybe y'know already what causes the screen to flicker and its the film-like circuit that connects the phone&screen interface to the other side of the phone. Is it really normal that the film-like circuit wires (I just dunno the technical term) connecting the phone&screen interface to the other side of the phone (CPU?) does not last? You mean it naturally wears out because of close-open mechanism? Should I spend for replacing this stupid thing every 6 months or every year? *Sigh* Wonder if Nokia could improve their hardware and circuit design.
