Smart idea. I get a similar effect when I logout of sites like Twitter and have to face a login page when I revisit. It breaks me from my unconscious loop and lets me decide that this is not actually how I want to spend my time. Do you think changing the pocket is enough, or rather its that you're switching your dominant/non-dominant hands?
It was really interesting to see what patterns switching pockets interrupted for me. One was the simple act of reaching for the phone - I had to consciously think about where it is. Then it feels unfamiliar to even start to pull it out of my left pocket. Then I have to decide to swipe and operate it with my non-dominant hand, or switch it over and use my right hand. There were more opportunities to break the cycle than I would have expected.
I was surprised to learn there are people who don't keep their phone in a particular pocket, who this wouldn't work for.
