Samsung UCA5 camera cannot be turned on in cold weather. Everything is normal in summer or when the weather is hot.

It used to be very cold. Can't you open it? If it started this year, it is likely that there is something wrong with the camera or the battery itself, not the weather. Under normal circumstances, it can be used below zero. Many crashes are caused by cards. Please format your card first, or take it down to see if it will crash. If it's not the card, it may be the battery contact or the hardware itself. These problems can't be solved by themselves, so send them to the maintenance point.
