I have an LG xenon. A few weeks ago my phone screen's color for everything use it for started flashing again again from normal color to negative. Now it changed to nagative and wouldnt change back to normal. everything that comes up on the screen is in negative but you can still distinquish the shapes of everything and its still usable but the change of color realy bothers. I dont want to buy another cuz i dont have enough money and i realy like this phone. what the hells wrong with it??
