How Do I Prepare My Phone for a Protest?

This is a most excellent place for technology news and articles.
You underestimate how much of a couch potato I am. Not moving is normal lol.
If I'm sitting on the couch, the phone is not on me. It's on the table next to me or on a counter somewhere. I don't even always look at it if I get a message. Sometimes I'll wait hours after I get a message to read it.
Even sitting on a couch moves your phone more than simply laying on a table. They can use accelerometer data to determine how, if at all, it moved.
For that , someone mentioned a roomba or straping it to a dogs collar..
