Open Up by Joshua Grist

The mentalist asks if they can borrow any random spectator’s iPhone (almost any phone can be used, it does not have to be an iPhone) and successfully unlocks it in a matter of seconds.

Naturally, there are many PIN code and phone code divinations on sale within the mentalism world, but this is unique in that there is no fishing, nothing said by the spectator, no hot-reading, and it's extremely simple. The spectator says absolutely nothing throughout this process, and if you chose to perform this without patter it would take around 5 seconds.
