From Nikon Europe:
It has recently become clear that in some very rare cases, if the camera is subjected to a strong shock such as being dropped or struck, heat may be generated from inside the camera and the top cover of the Nikon COOLPIX L25 may become deformed and a small gap may be visible near the shutter-release button. This may occur regardless of whether the camera is turned on or off. There is no danger of fire.
Area where the camera may be deformed and/or a small gap may appear after a strong shock is shown below.
What to do if your camera is subjected to a strong shock
If your camera has received a strong shock, remove the batteries immediately to prevent further problems. It is possible batteries may become hot, handle them with caution.
