It is a confirmed problem with my EVO. I rarely turn off phone, but when I do, I hold power button to get the screen to power off. I hit POWER OFF. Phone shuts down. But when I try to turn it on again, it doesn't do anything. Every single time I have to take the battery out and put it back again to make it work. Does anyone else have had this problem? This is the only problem I have encountered with my EVO. Is it a defective phone? Can I change it for another one?
