WiFi settings
Is it good or bad to let my phone automatically search for wifi networks in the background? Or should I manually turn it on as needed? To sum it up what are the pros and cons to letting let my phone automatically search for networks?
Another reason to leave Wi-Fi on; it is essential for navigation apps and for Find My to work correctly. GPS only works outdoors with a clear view of the sky. So thick tree cover or tall buildings can block the phone’s “view” of the 4 (out of 30 satellites necessary for accurate positioning. Apple (and other manufacturers) have mapped the locations of hundreds of thousands of Wi-Fi hotspots around the world, and use the nearby ones to make identifying your position much more accurate. It doesn’t connect to any of these networks, it just receives their broadcast to triangulate your position accurately; this is called aGPS, or Assisted GPS. And it works indoors, not just outside. So if you go, say, to the American Museum of Natural History in NYC you can search for “T-REX” and it will give you directions to the Hall of Saurischian Dinosaurs. Or at the Louvre in Paris, to Mona Lisa. Or you could just ask a guide or guard 😈
