This year, the California Electronic Communications Privacy Act goes
into effect. CalECPA requires police to get a warrant before searching
your electronic devices. It will be up to a judge to decide if police
have probable cause to access your devices, location information and
search history.

That sounds great but it still doesn't stop them from looking. It only
means they can't use the information in court.
They still can use the information to "get lucky" in a traffic stop or
know where to look to find legal probable cause from a place where you
don't have the expectation of privacy.
