Not really because when I charge it with some cheap generic ones found in quickie marts it shows this behavior, but I charge with motorola charger in my office and its perfectly fine, at home I use computer to charge it. and I remember someone on one of the thread mentioned it had to do with how the wiring on the outlet was earthed, and well it seems it was the case I used the same charger that showed this on my N9 on different outlets, friends home, in office and my own home and in class. In friends home it is perfect, in office it is perfect but in school and my home it makes the screen go ape ****.
