Nothing has released Nothing OS 3.0 April update for the Nothing Phone (2a) Plus. The update comes with the build number PacmanPro-V3.0-250410-1524-IND and has a size of 211 MB.

One of the highlights of this update is the introduction of the Nothing Gallery. However, there are no big changes to it, as the app was already available earlier through the Google Play Store. This update might have only brought some optimizations to make it smoother.

Another new feature is a shortcut to quickly Clear All apps. Now, users can long-press and swipe up in the Recent Apps menu to clear all running apps. It’s worth noting that this feature had already come earlier through a Nothing Launcher update.

To improve security, Nothing has added a power-off password verification feature. This prevents someone from immediately turning off the phone if it is lost. You can find this option by searching “Power off verify” in the Settings menu.

The update also brings a new toggle that lets users disable the unlock vibration on the lock screen. You can change this setting by adjusting the touch feedback options.

In addition, the design of the pop-up view has been optimized to make it look and work better. The phone also receives the latest April 2025 security patch, helping to keep it safe from new threats.

Lastly, Nothing has worked on improving system stability and has fixed an issue where emergency dialing could fail in rare cases in certain areas.

Overall, this update brings important improvements and security updates, even though some features were already available earlier. Users are advised to install it for a better and safer experience.

Essential Key remapping on the Nothing Phone 3a and 3a Pro allows you to unlock powerful custom shortcuts without rooting your device. By default, the Essential Key opens Essential Space—a built-in tool to capture screenshots or voice notes—but many users find it unnecessary or underwhelming.

With just a few simple ADB commands and the help of an app like Key Mapper, you can change the behavior of this button completely. Imagine launching your camera, toggling the flashlight, opening Instagram, or even starting BGMI, all from a single button press.

Thanks to insights from Reddit user u/acruzjumper, here’s how you can fully customize the Essential Key.

Why Remap the Essential Key?

If you’re not using Essential Space, that button is being wasted. Remapping the Essential Key gives you:

• Instant access to any app or system tool
• More control over your Android experience
• A way to make your phone feel more personal and useful
• Extra functionality without installing any complex mods or rooting

What You’ll Need

• Your Nothing Phone 3a or 3a Pro
• Either a PC with ADB installed or an Android phone with Termux
• Key Mapper app (available on the Play Store)
• USB Debugging or Wireless Debugging enabled

Step 1: Enable Developer Options and Debugging

1. Go to Settings > About Phone
2. Tap Build Number 7 times to unlock Developer Options
3. Go to Settings > System > Developer Options
4. Enable USB Debugging and optionally Wireless Debugging

Step 2: Connect Your Device to ADB

Option A: With PC (Windows or Mac)

1. Download Platform Tools from Google’s Android developer site
2. Extract the ZIP and open the platform-tools folder
3. Connect your phone to the PC using a USB cable
4. Open a Command Prompt or Terminal in that folder
5. Run the following command:

   adb devices
   

   You should see your phone listed. If yes, your setup is complete.

Option B: Without PC (Using Termux on Your Phone)

1. Install Termux from Google Play
2. Open Termux and install ADB tools:

   pkg update && pkg install android-tools
   

3. Enable Wireless Debugging on your phone:
   • Go to Settings > System > Developer Options > Wireless Debugging
   • Tap Pair device with pairing code
   • Note the IP address and port number shown
4. In Termux, run the following commands:

   adb pair localhost:<pairing_port>
   adb connect localhost:<connected_port>
   

   Your phone is now ready for ADB commands directly from Termux.

Step 3: Disable Default Essential Key Functions

Once ADB is connected (via PC or Termux), disable the system apps tied to the Essential Key:

adb shell pm disable-user --user 0 com.nothing.ntessentialspace
adb shell pm disable-user --user 0 com.nothing.ntessentialrecorder

This stops the button from launching Essential Space or triggering built-in voice note features.

Step 4: Install and Use Key Mapper

1. Download Key Mapper from the Google Play Store
2. Grant all required permissions (Accessibility, Input, etc.)
3. Tap the + icon to add a new mapping
4. Tap Record Trigger and press the Essential Key
5. It will be detected as unknown keycode 0
6. Choose the action you want (e.g., Launch App > Camera)
7. Save the configuration

From now on, every time you press the Essential Key, it will perform your chosen action.

Step 5: Example — Launch Camera

If you want the Essential Key to open the default camera app:

• In Key Mapper, choose Launch App and select your Camera app
• Or test manually via ADB:

  adb shell am start -a android.media.action.STILL_IMAGE_CAMERA
  

How to Revert to Default Behavior

If you ever want to go back to the original setup, just re-enable the disabled packages:

adb shell pm enable com.nothing.ntessentialspace
adb shell pm enable com.nothing.ntessentialrecorder

Then reboot your phone. The Essential Key will once again open Essential Space and voice note tools.

Final Thoughts

The Essential Key on the Nothing Phone 3a and 3a Pro is capable of much more than its default setup allows. With a few minutes of configuration, you can make it truly essential to your everyday phone usage. Whether you’re launching apps, automating tasks, or simplifying navigation, this remap trick is a great way to level up your Android experience.

And best of all, it works completely without root.
