Screen colours are all messed up-help!
My Samsung note 10.1 was working fine yesterday but today, for no known reason the screen has gone funny - kind of negative or faded. I've tried switching the negative button in settings but this doesn't change it back to its proper colouring. I've also done a factory reset and no change. I haven't dropped or damaged the tablet and there are no visible issues other than the colours in the screen. I've only had it a few weeks- it was a refurbished model from tesco. I really need to use it for work. Can anyone help with why it's done it, how I fix it or even what it is thats happened
Es esta una buena pregunta?
