If the Nevada measure passes, it would allow police to use a device known as the "textalyzer," which connects to a cellphone and looks for user activity, such as opening a Facebook messenger call screen.

And how does it access the phone without being unlocked? My phone only gives a recharge option, unless I unlock the phone, and set the usb to drive access instead of power-only.
And once in, how does it record the evidence for court? Does it print out a receipt that says "there was activity recently", or does it actually say what and when that activity was? (Despite not collecting any user data...?) If the person refuses to allow phone access, how does this information do anything if the police need a warrant and the phone isn't 'textalyzed' until hours or days after the incident?

This will be tricky.

Remember the Sutherland Spring Shooter?

The FBI tried and tried to unlock his iPhone. Neither Apple nor the carrier would cooperate.

They finally got the info they needed, but Privacy Laws prevailed.
