Random Shutdown Bug, DIFFERENT from the power switch issue

I just updated my Fuze to v.10.10.15A and I have same issue like yours. It will happen ONLY if I change the backlight setting to 5 seconds. The song will stop playing after the backlight went off. I tried to change brightness setting to low level (+2 from minimum level) and the backlight is set to 10 seconds then this issue won’t happen. I think the brightness setting is nothing to do with this issue.
