My lumia 925 with wireless charging shell comes in without worries. Everything seems sealed. Once closed, even the air does not come out. I did a test with a tissue, which is totally dry out again after 2 hours at the bottom of a water seal.
No worries to use the touch screen lumia 925. The photo is taken without worries (By cons not via the front camera, which is obstructed)
Negative: Difficult to open the locks with wet hands.
