9c is slow, and sometimes freezes up with black screen.

I have been battling the slow down and crash for about 4 weeks. Multiple calls to Sprint Tech support resulted in the suggestion that I remove the battery for two minutes and clear out any text messages, Internet files, and to kill all applications. I'm also running Good, their technical support suggested that Sprint was the culprit, and Sprint pointed to Good. The only thing that brings it back to life is a master reset. After the first couple of times a master reset isn't all that bad. For reference there are no additional applications on the phone just Good.

very possible you may have a defective device. Have you considered swaping it out?

that is my next step - This is my second Q9c, on the first the keyboard died.

my first Q did the crash & die thing, had no apps on it either. Could be a bad internal memory chip

Is it showing 100% CPU usage in the Task Mgr with nothing running??

I am having a very similar problem. 2nd phone and both times it would freeze up and not boot up. They even tried a master reset. Nogo
