Every time Apple updates iOS 18, like with iOS 18.4, they sneak in a few surprises for your iPhone. You’ve probably heard about turning doodles into awesome art, tweaking your home screen, making custom emojis, and exploring Apple Intelligence or Visual Intelligence.
But what else is hiding in iOS 18.4 that’s flying under the radar? There’s a lot to uncover! Apple adds settings that don’t get much attention, but they’re super handy. Here are some of my favorite secret iOS 18.4 features worth checking out.
Power Off Your iPhone Without Buttons
No need to press physical buttons to restart your iPhone anymore. The updated control center has all the usual stuff—brightness, volume, Wi-Fi, Bluetooth—and now includes a restart option. Just swipe down from the top-right corner, press and hold the power icon in the control center’s top-right, and a slider pops up to shut down your phone. To turn it back on, you’ll still use the side button.
Share Wi-Fi with a QR Code
Sharing your Wi-Fi just got easier. With iOS 18.4, you can create a QR code for your network. It’s perfect for sharing with a group, someone not in your contacts, or even Android users. Open the new Passwords app, find your Wi-Fi network, tap it, and select “Show QR Code.” Anyone who scans it with their camera connects instantly.
Tweak Your Flashlight’s Beam
The iPhone flashlight isn’t just brighter—it’s smarter. On supported models, you can now adjust the beam’s width. Go wide to light up more space or narrow for a focused glow. Turn on the flashlight from the lock screen or control center, and swipe left or right on the Dynamic Island to play with the beam. It’s great for setting up photo lighting!
