Enable scanner gestures
In case you didn’t know, some newer smartphones allow you to drag down the notifications shade by swiping down on the fingerprint scanner. This is a handy trick to have up your sleeve if you’re using your phone one handed or aren’t excited about the hand gymnastics required to shimmy up to the top of the phone, specially on one as tall and slippery as the S8.
Go to Settings > Advanced features > Finger sensor gestures and flip the switch to on. Now you can swipe down and up on the scanner (if you can reach it) to drag down or pull up the notifications shade.
Change quick settings tile size
As you may have guessed from a few entries above, I like to maximize the sense of space on my phone. The Galaxy S8 has another nice built-in option that lets you squeeze a little more info on screen. Just pull down the Quick Settings panel from the top of the screen, either with a two-finger swipe or two single finger swipes, and tap the overflow menu in the top right hand corner (the three vertical dots).
Tap Button grid and choose the one you prefer. You can make the toggles larger or smaller, but if you go smaller, in a 5×3 grid (as I recommend) you’ll be able to get almost all of your Quick Settings tiles on the one screen. Hit the overflow menu again and tap Button order to drag the toggles around. This lets you put the most important ones for you on the first screen, negating the need to swipe to the second panel.
As you no doubt have heard, the Galaxy S8 ships with its QHD+ screen set to FullHD+ resolution. This was presumably set as the default option to eke out additional battery life and to be fair, most people probably wouldn’t even notice it’s not 2K.
But, if you want the very best out of your Galaxy S8 – especially if you’re picking up a Gear VR to go with it – then you’ll want to bump that default resolution up to the full QHD+.
Go to Settings > Display > Screen resolution and drag that slider over to the far right. Note that this will consume more battery life, so if you don’t notice a significant benefit, perhaps consider dropping it back to FullHD+ or even HD+ when battery life is important.
