Apple today released iOS 18 Beta 3 and iPadOS 18 Beta 3 for developers, continuing to refine and add small changes. Below is everything new I have found in Beta 3 so far.
In case you missed it, here are the features included in iOS 18 Beta 2 →
What’s New in iOS 18 Beta 3 Update (Revised version released on 15/7)
Emoji Keyboard Changes
In the iOS 18 Beta 3 Update, the Emoji keyboard has now reverted to its previous state. In the iOS 18 Beta 3 released last week, the Emoji keyboard was adjusted to be larger and included both your Memoji and Stickers.
It’s unclear whether this is a bug or an intentional change by Apple.
Fixed Tinting Icon Bug
The tinting bug where icons are getting darker than the color you choose introduced in Beta 3 is fixed in Beta 3 Update. They’re actually usable now.
Here are the other changes in iOS 18 Beta 3 
Dark Icons for Third-party Apps
Some third-party apps now have dark icons after updating to iOS 18 Beta 3 without the developers needing to update their apps.
Emoji Keyboard Update
iOS 18 Beta 3 makes emojis on the keyboard bigger, with more space between them.
Additionally, in Messages, the Emoji keyboard now combines emojis, Memojis, and stickers into a single interface. You can swipe back and forth to browse different tabs dedicated to Stickers or Memojis.
Flashlight UI Update
When you turn on the flash on an iPhone with Dynamic Island, now the flashlight UI will be significantly larger, allowing you to easily adjust the brightness and spread of the flashlight.

New Music Button on Lock Screen and Control Center
iOS 18 Beta 3 also adds a button to open Music from the Lock Screen or Control Center
RCS Messaging Settings
iOS 18 Beta 3 has changed the RCS Messaging settings to a tap-in menu. In iOS 18 Beta 2, this option was shown as an on/off toggle.
RCS Expands to More Carriers
iOS 18 Beta 3 has expanded RCS messaging capabilities to more countries outside the United States. For example, carriers like Videotron, Telus Mobility, and Bell in Canada, Telefonica in Spain, SFR in France and O2 in Germany.
Maps Icon
The Maps app icon now looks much more vibrant when Dark Mode is activated.

New Dynamic Wallpaper
The iOS 18 wallpaper now includes a Dynamic version that changes colors based on the time of day.
Reminds me of the macOS Ventura Dynamic wallpaper.

Photos App
In iOS 18 Beta 3, Apple has removed the border in the default photo/video viewing mode.
Additionally, the Select button has now been added to the default view in Photos, and the search button is now just an icon and is colored blue.
Control Center
Apple has changed the tap behavior for the Connectivity module. Now, when you tap on the AirDrop, Wi-Fi, or Bluetooth controls, submenus will appear instead of requiring a long press as in Beta 2. A small arrow icon has been added to the right side to indicate that you can now tap once on the control.
To turn off or disconnect a control, tap on its icon.
Control Center Settings
There is an animated illustration in Settings - Control Center to guide you on how to customize and use the new Control Center in iOS 18 Beta 3.
Vehicle Motion Cues Settings
The Vehicle Motion Cues setting has also been updated to a tap-in menu in Beta 3, in Beta 2 this option was shown as an on/off toggle.
Apple TV
The InSight feature is now working in the Apple TV app in iOS 18 Beta 3 (and tvOS 18 Beta 3).
This feature is similar to Amazon Prime Video’s X-Ray, showing information about actors and songs currently on screen.
Single-square HomeKit Control
iOS 18 Beta 3 brings back the 1x1 size control for HomeKit accessories in Control Center. This option was available in Beta 1, but for some reason, it disappeared in Beta 2.
Battery
In Settings - Battery, there’s a new reminder that the update will finishing in background, and you can use your iPhone as usual. This process will take some time, and during it, your iPhone’s battery may drain faster than normal until the update is finished.
