upon starting up, the display shows the wallpaper and icons at about 4 times their normal size. I am unable to move the screen to get access to all the icons on the page. This has rendered the Mini useless as I am unable to get in to Settings to attempt to troubleshoot the problem. I cannot get at the Slider to shut down the unit. I have had to revert to pressing both buttons at the same time to shut the unit down.
