recently, i found my N810 often enters to a state that it doesn't repond to either touch events on the system or the switch keys.later i found one trick to make it reponse again by pushing the power button, then the original issued key will firstly reponds, then the shutdown menu, it's quite annoying. any others have the same issue? thansk.
meanwhile, i observed lots of EAC related messeges:
