Phone randomly awakes from sleep mode ¶ 

Your phone is in its case and without you pressing any buttons or sliding it open, the screen activates.

A magnetic case is awakening your phone ¶ 

This is a common problem among Fortress users. One possible cause is that if your carrying case has a magnet fastener, it could be triggering a signal inside the phone, telling it to wake up. You can either get a new case for your phone, remove the magnet from the case or get a case with magnets only on the sides, as cases with magnets in the center tend to cause this problem more than others. Also, if your case is made by your provider, you may consider purchasing one here.
