Taking photos in full light is fine. When the flash is used there is a major problem. The phone completely goes black and is locked up. This has happened several times over the past few weeks. The only way to restart is to remove and replace the battery. The last time the phone rebooted, a message came up saying that the battery was not supported (it's the Samsung battery shipped with the phone)! I've installed firmware updates, but there was no change. Anyone else have issues with the Charge flash/photo?
