Apple's iOS 16 is expected to release sometime in the fall, along with a number of big-league features, including a completely redesigned lock screen with widgets and vast customization, as well as the ability to unsend and edit text messages and help prevent silly mistakes.

However, these features are just the beginning. You'll be excited to learn that there are several new hidden features that could completely change how you use your iPhone.

If you want to take a closer look at some of the hidden gems that iOS 16 has to offer, like password-protected photo albums and easily accessible Wi-Fi passwords, here's what you need to know.

And if you want to learn more about Apple's latest mobile operating system, we've got new iOS 16 features that you'll love and a couple of Apple Maps features that will improve how you travel.

You can also get your hands on iOS 16 right now. Check out how to download and install the second beta on your iPhone.

Pair Nintendo Switch Joy-Cons with your iPhone

Apple has long allowed you to pair third-party controllers, like the PS5 Sony DualSense and Xbox Core Controller, to your iPhone and iPad, in order to more comfortably play mobile video games like the Apple Arcade library, Minecraft and Call of Duty. And you can add another console controller to that list.

If you own a Nintendo Switch, you can now pair your Joy-Con controllers to your iPhone or iPad running iOS 16. To start, hold down the little black pairing button on the Joy-Con, until the green lights start running back and forth. This means the device is in pairing mode. Next, open your iPhone and go to Settings > Bluetooth and select the Joy-Con from the list. Repeat this step with the other Joy-Con.

Hidden and Recently Deleted albums are now password protected

The Hidden album in the Photos app is clearly not hidden, seeing as you can easily find it, making it impractical for adequately hiding private photos and videos. While Apple does have an option to make the Hidden album "invisible," anyone with access to your phone can make it visible again and view everything inside.

Thanks to iOS 16, you can now lock the Hidden album. You don't actually need to do anything to toggle this feature on. If you want to check it out, launch the Photos app and go to the Albums tab at the bottom of the screen. If you scroll down, you'll see a tiny lock next to the Hidden and Recently Deleted albums. To view what's inside, use Face ID or your passcode.

View and share saved Wi-Fi passwords

Apple has allowed iOS users to share Wi-Fi passwords for a while now, but only by placing two Apple devices near each other. And if that feature didn't automatically work, you couldn't just dig out the password from your settings. Plus if you wanted to share a saved Wi-Fi password with someone else, like an Android user or someone on a computer, you had to know the password. Until now.

In Settings, go to Wi-Fi and tap the tiny information icon to the right of the network you want the password for. To view the network password, tap the Password section and then use Face ID or enter your passcode to view it. You can then tap Copy to copy the password into your clipboard and share it.

Find and remove any duplicate photos and videos

Maybe you've saved the same photo multiple times or downloaded a video more than once, and so you've got duplicates littered in your photo album. It may not be a problem if you've got the storage to spare, but if not, it might be a good idea to go back and remove every single duplicate -- which is now easy to do on iOS 16.

In Photos > Albums, you should now see a new Duplicates album under Utilities, where Apple scans through all of your photos and shows you any photo or video you've saved more than once. From there, you can either delete any duplicates, or simply press Merge, which will keep the photo with the highest quality (and relevant data) and then move the others to the trash.

Although you'll probably want to go through each set of duplicates, to ensure that they're actually exact copies and not similar photos, you can also hit Select > Select All > Merge to remove every single photo and video that Apple thinks is a duplicate, all at once.

Pin your favorite tabs in Safari

Safari caps your open tabs at 500, and if you're nearing that limit, it might be pretty darn hard to find the exact tab you're looking for. You could scroll endlessly, but there's now an easier way to find the exact tab you're looking for.

In Safari, if you press down on an open tab, you now have the option to hit Pin Tab. This will move that tab to the top of Safari, where it will exist as a tiny tab preview, permanently pinned there, which you can then tap to view.

If you press down and unpin a tab, it will move to first in your grid of open tabs.
