My Emberton II worked great for a couple of months. I really liked this little thing and was already planning on a larger model for home use. But since a couple of weeks I cannot shut down the Emberton anymore. When I press the center button, it shuts down as it always did, but shortly after it just turns on again and connects to my phone again. And it keeps on doing this until the battery is completely dead.

I have already tried disconnecting all attached devices, doing a factory reset, but the problem just remains. Can something be done about this or is it just faulty?
