Sometimes when i want to record slow motion video and select the option to record i get silver lines across the screen. Just like the old TV's when they were not in tune on a channel. Very annoying when you want to record sth quick. Then you must wipe camera data and it's good for another try. It happens not all the time but occasionally. Sometimes even the camera freezes and you can't to nothing but to restart the phone. This occasions happen only when i want to film slow motion or time laps.
