On my Casio EX-Z300, there are 2 strange things. The date and time of a photo as well as white balance can be changed during playback. I find this weird as I've never seen it before. Changing the White Balance can be useful if the photo is too blue but who would want to change the date and time that a photo was taken? I accidentally did that while setting-up since the camera comes with no user manual. I had to waste time resetting the date and time of that photo.
