I just got a replacement iPhone 4 from Rogers last week. I updated it to 4.3.2 and have read that there is a bug which says "the flash cannot be used, the phone needs to be cooled down first" (that's basically what the message says) I'm not so bothered by this as I've read this is pretty wide spread....is this happening to you too? Try these steps to find out.... Open camera app flip the shutter to the front camera open the camera roll (bottom left hand corner) press done (top right hand corner) switch camera to the back camera view look to the top left where the flash button is and you should now see a triangle and when you press it you'll then see the error message if your phone in fact has this bug Now why I'm really here is I want to ask you all if when you touch the screen to focus in on something does the blue square take forever to focus and then disappear? Or does it just keep on trying to focus and never disappears unless you move your phone Also even when using HDR my photos are turning out so crappy with the lighting and shadows...is this also happening to you too?? Please advise! Thanks.
