I've lost count of the number of times per day that I've opened an app or changed screens when I didn't mean to. Getting out of the wrong screen is easy enough: You just tap the home button or turn off the screen. But why does it happen in the first place?

While unintentional tapping happens on every phone, the Galaxy S10 phones' slimmer bezels leave less buffer room for your grip. This is in service of giving you more screen, but your hands still have to go somewhere. Samsung's software is meant to resist accidental presses like this, but there's only so much it can do.
