[ONE Original Android Development] olly2009:
Phone got stuck twice tonite after standby, black screen only navigation keys lit when turning the phone on. I did the long press power button to turn it off and then connected the phone to my computer. Weird thing then happened: multiple drives were added (F,G,H,I) only F was readable with one folder called 'image' with the following content, for other folders Windows said the file system was not recognized. Another long press on power and then phone boots fine. Can anybody give me directions how to further investigate the culprit?

Edit: Did some research and it seems similar to that Galaxy S4 CM11.0 issue here : http://xdaforums.com/showpost.php?p=53130428&postcount=67.
