A note to all Galaxy S8 users: fast charging only works while the screen is off

These days, a smartphone having some sort of fast charging solution has become the norm, not the exception, so most people would be excused for forgetting about the feature. So this is a friendly reminder that the S8 features the exact same technology as its predecessors, the S6 and S7, did before it. Samsung Adaptive Fast Charge, which is really just another name for Qualcomm's Quick Charge 2.0, still does its job as well as it did a couple of years ago, of course, but it does so with a small limitation: you can't use it while your device's screen is on.
