Hello @boldhill62282. The lens cover on a HERO5 Black camera is removable and replaceable. Water getting inside it indicates that either the O-ring seal on the lens is defective, or the lens is not properly mounted. See how it is done here: https://youtu.be/jDCTa3lCdMA .
If the lens is faulty, a replacement part for sale is available at https://gopro.com/en/us/shop/accessories/protective-lens-replacement/AACOV-001.html . You may also reach out to our Support team at
