I have tried searching google and even the official forum of Playstation about this, and yet no one really has an idea on how to fix this.
To start this off, I have not modded my PSP in any ways, and just recently, the home screen will continue to pop up while I'm playing an UMD game and without me pressing the home button. To be more specific, whenever the UMD is being read in a certain manner, the home screen will pop up.
Does anyone have any idea on how to fix this?
