I called GoPro support.
The answer was that a problem may be occurred in using my Gopro in underwater.
So I have already asked the support to change my GoPro using GoPro plus.
I shipped it to the Gopro Office in Sigapore via UPS service and It arrived last Wedensday.
Exchange fee was 10,100 yen.
I think a little expensive in just 1 year use, but I look forward to getthing a new one.
