not sure i understand you correctly, but several times i experience that  
the fr, while seemingly in suspended state, answers to a screen tap  
showing several console messages (whihte font, black background) and then  
switching to the lock screen.

otoh, what i meant was: when the fr frequently wakes up the screen becomes  
sensitive and any tap would prevent the fr from going back to suspend --  
so if in one of these moments of short resumes the screen ist tapped and  
again and again the fr would never resume thus draining the battery  
quickliy.
