Keeping current with system updates is the single most important thing you can do to keep your phone safe, and long ago, installing those updates was an incredibly slow process. But back in 2016, Google tried to make things better with new "seamless updates" that made it an easy background process — you could even use your phone as they installed. Since then, most phone manufacturers have come around to the idea, with one very big exception: For whatever reason, Samsung refuses to give its phones the feature. Even its latest, $1,400 Samsung Galaxy S20 Ultra uses decidedly non-ultra, antiquated, super-slow updates that knock your phone out of commission for a solid 3-15 minutes as they install.
