G7x Mark 1 control issues underwater only

[xrcjdx]

Greetings,
I've taken my g7x on a couple hundreds of dives, in a Fantasea poly housing, with no issues. Lately, there are times when the zoom, aperture, and shutter speed functions will not respond. They all go south at the same time. Usually restarting the camera helps, but sometimes not. This never occurred on the surface.
Any thoughts what could be causing this?
Any insight would be appreciated. Thanks!

The most common cause of this (lots of reports of strange behavior at depth) is one (1) of your housing controls is slightly pushing one of the camera buttons.

Most common cause is not seating the camera properly. Second cause is a control out of alignment.
