Hi, my android asus tablet used to work fine, i gave it to my cousins to play with it last week and then when i got it back, they said the touch screen isn't working properly. When i turned it on, it looked fine. However when i try and press the home button, or something else it goes crazy. In other words, when i press the home button or any other button it will automatically taps buttons by itself sometimes. I have to keep twisting the tablet just to get some numbers to work. It is always like this. Sometimes it just opens another app when i'm asking it to open another app. Sometimes some of the buttons tap sensors or whatever don't work and i have to twist the device to get some of the tapping to work. Please help me! Thanks.
