Every Android phone or tablet has them, they’re just hiding in plain sight. Google chooses to hide them on most phones, that way average users don’t mess up their phone. However, there are instances where you’d want access, and that’s where we come in.  Our video below will show you what to do, where to go, and how to hide those settings again when you’re done.

Before we begin, it’s worth noting that this entire menu is for advanced users. Changing some of the settings or control can significantly alter the experience on your Galaxy S9. And not in a good way. While there are a few useful controls in here, almost everything else is specifically for developers.

How to Unlock Developer Options on Galaxy S9

To start, simply follow our instructional video above. It shows you everything you need to do. If you can’t watch the video, here are the step-by-step instructions, and screenshots of what you’re looking for.

  • Head to Settings in the app tray, or pull down the notification bar and tap the gear-shaped settings button
  • Scroll down and select About Phone
  • Tap on Software Information
  • Now, find Build Number

  • Find Build Number and tap on it 4-5 times quickly
  • You’ll see a pop-up that you’re a few taps away from unlocking the menu
  • after 4-5 taps you’ll see a confirmation that “Developer Mode has been turned on”

That’s it, now, simply hit back and scroll to the very bottom of the settings menu on your Galaxy S9. You’ll see a brand new option in settings named Developer Options.

Again, be careful inside the developer options menu, and only change things you understand. Otherwise, you can quickly cause more harm than good.

Other Details

There are a lot of cool things the Galaxy S9 can do. Once you unlock the developer options menu, try this trick to speed up your phone in three easy steps. This is also where you go to enable USB Debugging, a step you’ll face in a lot of how-to guides or while trying to backup your Galaxy S9 before a big software update.

At the end of the day, just remember that Google hides most of these options or controls for a reason. So, once you’re done using the developer options menu we recommend hiding it again by tapping the switch at the top right while you’re in the developer options settings menu. This will hide it again, and remove the option from your phone until you unlock it later. Before you go, take a peek at these 15 Common Galaxy S9 Problems & How to Fix Them.

9 Best Galaxy S9 Screen Protectors

WhiteStone Dome Tempered Glass (UV Install) ($44)

The first screen protector we'll recommend for the Galaxy S9 is the impressive WhiteStone Dome Glass kit. This isn't for the faint at heart, and it's pretty expensive, but it's worth it to protect your $800 smartphone. 

WhiteStone uses a special liquid installation process where you manually install the screen protector, then use a UV Dome Light machine to "cure" the liquid. This provides the absolute best screen protection experience for curved devices like the S8 and S8. The video above is a review of their product for the Galaxy S8.

It's not permanent and can be removed if necessary, so don't worry about that. Basically, where most glass protectors don't fit right or have gaps on the screen where touch sensitivity fails, this one won't. The liquid fills in the entire area, then curves the glass to the screen. These typically run around $60 but are often on sale for $40, which is still less than a ZAGG InvisibleShield. Stay tuned for a full review, or get one right away for your S9.
