I purchased this GoPro last month. I ran fresh water after I used it in the salt water. I only used it twice to change the battery. It is difficult to open.
The USB Slot opens up easier compared to the battery/SD Slot. Is this Normal?
Clean your camera , notesd t othe end of the manual under maintenance. then take on a cloth selicone lube spray if you spray teh door then PROTECT it all wit ha glad bag. and wipte it clean.
I did clean it. It is the push button that is difficult to push in to open the slot for the battery/SD Slot.
Please contact GoPro Customer Support.

If hte push button is jammed with a grain of sand did you try a few times t orelease it or toss some can air on her? on a cue tip a dap of lube over the door and wipte quickly.
