my tablet has recently got a speaking lady when I touch an application she just names it. Besides the apps are very hard to open and I have to touch the screen several times. First three is a yellow box around the app which has been touched several times and then it opens with the other several touches. The screen does not move if tried by a single finger and I have to use two fingers together to scroll up or down on the screen. Does anybody know the reason. thanks in advance :-)
