The Cinera dont boot since yesterday.
It hangs up before android starts or shortly afterwards. Only a black image is displayed. I then have to press the power button for 5 seconds to switch off the Cinera.

Is there a Reset for the system or what can I do?

Thanks.

chframus The Cinera Prime has a proximity sensor. If it's activated then you will have to keep the device on you're face until the screen lights and then you can navigate the menus to the location where you can deactivate the proximity sensor
