What can interfere with phone GPS?
GPS signal interference can be caused by malfunctioning or incorrectly configured transmitters, which can inadvertently broadcast signals in the same frequency range as GPS transmissions. GPS interference can also be intentional, when jamming devices emit signals in the GPS frequency.
What disturbs GPS?
In some cases, satellite malfunction or solar flares can temporarily disrupt the transmission of GPS signals. A GPS jammer is different though in that it sends out radio signals or signal noise with the same frequency as the GPS device, to override or distort the GPS satellite signals.

How accurate is phone GPS?
If you're outside and can see the open sky, the GPS accuracy from your phone is about five meters, and that's been constant for a while. But with raw GNSS measurements from the phones, this can now improve, and with changes in satellite and receiver hardware, the improvements can be dramatic.
Can GPS make mistakes?
When signals from the GPS satellites bounce off buildings, the GPS receiver can be confused by the extra time the signal took to reach it. In these cases, you may observe sudden large errors in position.
