Not exploring the Settings menu of a new device. That should be the first thing you do when you first power on a new device. Most people just go with whatever the default settings are. Hell, some have never even seen their settings menu beyond the wifi connection.

I’m weird with this. Usually when I get a new phone, laptop or whatever, I like to use it exactly as is for at least a day or so. I like knowing what the “default” user experience is without me having to change or “fix” things first. Like playing a game without mods for a playthrough before adding big tiddie dragons.
