Dead screen? Here comes the mouse!

Device complies as far as the expectations. Aaaber: I had initially thought it would be defective. Even after prolonged "load time" did absolutely nothing on the display. At this point I wanted to complain about the device, such as a variety of other customers and send them back. The solution: press the small reset button with a straightened paper clip into the middle. Is nothing like this in the instructions. But now it works. What good is us as a mega screen if you only have to operate as a hiccup. Gebauso stupid: The lid of the lithium batteries is only my special triangle screwdriver. Why not with ner Flex ???
