Will the magnet interfere with the phones function?
For all you oldies who still think magnets will affect your phones function, mobile phones use SSD (solid state drives) which aren't affected by small magnets like ours. In fact your phone itself has over half a dozen magnets inside it to power features such as your speakers. The magnets will also have no impact on your GPS, we've clocked over 100 hours both driving and playing Pokemon Go (not whilst driving of course) and can verify this with personal experience.
