Re: Why won't any of my apps load?
Cant say this is a simple fix but could be. In todays world (unlike a world without smart phones) everything is electrical or runs on electricity or batteries. Often powering down or removing the battery could reset the system.
On a more serous note, the touch screen might have failed and it doesn't recognize that anyone is touching it.. and if you're using a styles.. Your odds of it not working have increase because the styles is not like a human touch.
Let's try the power down, reboot then battery out first. You might have to clean the batteries contacts just to be sure before one needs to take the phone to a repair shop for testing the screen.
