The beam also tells you how accurate your phone’s direction is at any given time. The narrower the beam, the more accurate the direction. The wider the beam, the more likely it is that your your phone’s compass is temporarily uncalibrated, which means that its sensors aren’t working as they should be. This can happen by doing something as simple as charging your phone or walking by a metal pole, which most of us do everyday. Thankfully, there’s a really easy fix. Any time you want to get back on track — not just when you see a prompt or notification — simply move your phone in a figure 8 motion a few times. This should immediately result in a more accurate direction.
