Nexus 7 magnetic sensor

Does anyone know a solution to the Nexus switch off the magnetic sensor?

I have in the car a magnetic holder or 2 to hold the tablet, but the problem is that is a holder exactly where the is magnetic sensor of Nexus and it therefore puts in sleep mode and can no longer be unlock long as the magnet is there ....

Znaps magnetic adapter

Been following their product on kickstarter, anyone planing to buy one of these? Having reversible charger like type-c is good IMO but don't know if it effects fast charging ability of note 5

Case for magnetic dock?

I have been using magnetic dock in my car with original nexus 5 and don't want to give this up. I'm afraid that sticking the magnetic plate inside a regular case will eventually destroy the back cover of the phone that is resting against the plate. Does anyone know of any case with built in metal plate for attaching to a magnetic dock or a two piece case that I can slide the magnetic plate between?
