I have an app called The Torch which basically turns the Bold flash on so you can use it as a torch but lately when I've been using it, I would lock the phone with the button on top with the torch on, then 10 mins later when I go to unlock, it does nothing! None of the buttons do anything! Its like the phone is turned off, but the light is still on! The only way to solve is to do a battery pull, which is annoying! Any ideas?
