They might not be the flashiest features, but Samsung’s new Galaxy S10 line has a subtler pair of upgrades that could meaningfully improve the experience of using them day in and out. All three new phones, the S10, S10 Plus, and S10E, include support for Wi-Fi 6 as well as 2 gigabit LTE speeds, up from 1.2 gigabits last year. The upgrades offer the potential for faster internet speeds, whether you’re connected to a cell network or just your home router.

Now, there are some big caveats here. For one, you’re never actually going to hit 2 Gbps on your wireless network — that figure is the phone’s theoretical maximum speed. But the higher figure reflects various speed-boosting improvements, which ought to translate to at least some real-world speed gains on networks that are equipped to take advantage of them.
