Everytime i test my BV7000 pro waterproof imerging it on water, the camera lens become blurry (condensation) and the Power button begins to fail, requiring you to press it much harder to function.
Is that normal ? What should i do ? I have also a Sansumg S5 (ip67)and it doesn't happen with it
What's going on ? Thank you

You jave to wait Ehen its dry again. If the issue is there Ehen its dry then replace the phone

Water that makes touch screen inputs is normal.

For the dead power botton, maybe this could help: Place the device in rice or drying-pearls for some days. Use the video to open it and check the buttons inside part. if there is water inside dry it and clean the parts with 99% alcohol. Hope that will help.
