Hi, every time I attempt to open any app, including most pre-installed ones such as 'contacts' it comes up with the following message: "This application X (process com.android.X) has stopped unexpectedly. Please try again" And it does it on all apps! The only item I can access is settings and my aftermarket task manager. I then decided to find the pre-built one in settings in case all of my memory was being used up for some unknown reason but i have around half of the RAM available. The internal storage is also full, but has been for weeks as I transfer everything to my SD card, which has nearly 500MB to go around. I would normally just switch it off and on again, but this has happened multiple times over the past 15 months and every time i have done this, my home screen resets and takes me up to half an hour to redo . On this occasion I will do this, but can anyone help me from preventing this constant closing of apps or provide me with a solution for the future? Thanks for your time, much appreciated.
