I have found weird issue. When I shoot photo with pro mode and exposure time above 13s in a JPEG format the photos turn out to be pink or purple. Photo with exposure time of 13s or less results in completely normal picture in JPEG format. With RAW format this does not happen. I know I am not the only one getting this weird issue. I guess there are some issues in image post processing. Is this known issue or does it only happen to some devices?
