Nothing has rolled out the Nothing OS 4.0 stable update for devices like the Nothing Phone (2a), Phone (2a) Plus, Phone (2), Phone (3a), Phone (3a) Pro, and Phone (3). Many users successfully updated their phones, but after the update, several settings are often ignored. These small mistakes can lead to lag, slow performance, battery drain, and unnecessary background activity.
But before that, it’s worth noting that the Nothing OS 4.0 stable update, which rolled out for multiple devices, was reportedly paused for the Phone (2a) and Phone (2a) Plus after many users said the update disappeared from their system update page. Although Nothing did not officially confirm a halt, the pause was believed to be caused by a confusing “Android Beta Program” message appearing after installation. A hotfix was released on 1st Dec, after which the Phone (2a) and Phone (2a) Plus got the OTA update.
To help you get the best performance, here are all the important settings you should change immediately after installing Nothing OS 4.0.
1. Restart the Phone Twice
After the update finishes, restart your phone once.
Wait a few minutes, and restart it again.
This helps the UI refresh properly and removes early lag or animation glitches.
2. Turn Off RAM Booster
On mid-range devices like Phone (2a) series or Phone (3a) series, RAM Booster can actually slow the phone down instead of improving performance.
Settings → RAM Booster → Turn Off
After disabling it, users often notice smoother performance.
3. Run the App Optimization Tool
Nothing introduced a new App Optimization feature in OS 4.0.
This clears cache, fixes app behavior, and improves battery efficiency.
Settings → Apps → App Optimization → Begin Optimization
Do not skip this step—it’s very important.
4. Disable Lock Glance
Lock Glance changes wallpapers frequently and performs background tasks.
This can affect battery life.
Turn it off:
Settings → Lock Screen → Lock Glance → Disable All Options
5. Restore Deleted Camera Presets
If you removed any camera presets by mistake, you can now restore them easily:
Camera Settings → Restore Deleted Official Presets
Useful if you rely on Nothing’s default film-style presets.
6. Enable Extra Dark Mode
Nothing OS 4.0 adds an Extra Dark Mode for deeper blacks.
It also helps users who noticed slight green tint issues earlier.
Settings → Display → Dark Mode → Extra Dark Mode
7. Try the New App Hide Feature
You can now hide apps directly from the home screen or app drawer.
Just long-press the app → Hide
Hidden apps appear in the Hidden Folder, accessible after verification.
8. Customize Quick Settings Tiles (2×2 Layout)
Quick Settings tiles like Wi-Fi, Screen Recorder, etc., can now be resized.
Go to Edit and change tile size to 1×1, 2×1, 2×2 for easier access.
9. Share Wi-Fi Password Easily
Nothing added a new “Share” button in the Wi-Fi panel.
You can instantly share Wi-Fi details through a QR code—no need to type the password.
10. Remove Essential Widgets for Better Performance
Essential Widgets created by community developers may use background resources.
If not needed, remove them to save battery.
11. Update All Apps After the Android 16 Upgrade
Some apps behave strangely after the update.
Update everything from:
Play Store → Profile → Manage Apps → Update All
Also uninstall unused apps to reduce background activity.
12. Reset Network Settings (If Needed)
If you face Wi-Fi, Bluetooth, or mobile network issues:
Settings → System → Reset Options → Reset Network Settings
This usually fixes the problem.
13. Avoid Third-Party Launchers
Launchers like Nova may cause lag on Nothing devices after OS 4.0.
Switch back to the default Nothing Launcher for best performance.
14. Recalibrate Battery for Better Backup
If battery drain feels unusual after updating:
- Drain phone to 0%
- Charge to 100% while switched off
- Repeat once more
This helps Android 16 stabilize battery management.
15. Enable Power Off Verification
A very important security feature:
When enabled, no one can switch off your phone without entering your password.
Settings → Security & Privacy → More Security → Power Off Verify
Highly recommended.
16. Adjust Flip to Glyph Behavior
Under Glyph Interface → Flip to Glyph, choose whether the phone should go:
- Silent
- Vibrate
when placed face-down.
17. Clean Up App Search Results
Want to remove contacts, messages, or calendars from appearing in app drawer search?
App Drawer → Three Dots → Search Result Settings
Disable what you don’t want.
Final Thoughts
Nothing OS 4.0 brings many improvements, but the experience becomes even better when these settings are adjusted correctly. These small changes help improve:
- Performance
- Battery life
- Smoothness
- Security
- Customization

Follow TechiBoy on Google to get updates on smartphones, gadgets, software updates, and more.
Kea: Button Remapper has received a major update that brings a new Floating App Sidebar, Action Combos, more customization options and several new features for Android users.
The update also brings a redesigned user interface with improved animations, blur effects and a cleaner overall look. While Kea remains available as a free app, some of the new features are available through the paid Kea Pro version.
Floating App Sidebar
One of the main additions in the update is the new Floating App Sidebar. It allows users to pin their favorite apps and actions and quickly access them from anywhere on the phone.

Users can add apps such as YouTube, Instagram, Gmail, games, and more, as well as actions, to the sidebar. The sidebar also supports customization for its position, number of rows and columns, background, icon style, and accent color.

The background can be changed between transparent, translucent and solid styles. Users can also choose different icon styles and customize the sidebar’s color using the available color options and color wheel.
Action Lab Combos
Another new feature is Action Lab Combos. It allows users to perform multiple actions with a single button press.
For example, users can create a shortcut that mutes media volume and enables Do Not Disturb at the same time. This can be useful during meetings when multiple settings need to be changed quickly.

Users can also create their own custom combos by selecting multiple actions and arranging them into a sequence.
Voice and Call Recording
Kea Pro also adds shortcuts for voice recording and call recording using the Nothing Recorder widget.

After setting up the required Recorder widget, users can assign a button press to start or stop recording. Saved recordings can then be accessed through the Nothing Recorder app.
More Customization
The update brings several new options for Kea’s visual overlays. Users can choose different styles, including Dark, Frosted and Smoke themes.

There are also different animation effects, while the position of the overlay can be adjusted for different hardware keys. Kea Pro users can further customize the accent color and use a color wheel for more control over the appearance.
More Features for Nothing Phones
Kea Pro also includes several features designed for Nothing Phone users. These include Glyph Torch and Glyph Timer shortcuts.
Users can assign these features to different button gestures. The app also supports shortcuts such as Circle to Search, QR code scanning and additional hardware button actions.

The app also supports volume button mapping and power button customization, giving users more ways to control different actions using physical buttons.
Free Version Still Available
Kea: Button Remapper continues to offer a free version with more than 30 actions and support for four different button gestures. The free version also includes features such as visual overlays, lock screen controls and a Quick Settings tile.
The Floating App Sidebar, Action Combos, volume button mapping, voice and call recording, Glyph shortcuts and other additional features are available with Kea Pro.
Kea Pro is offered as a one-time lifetime purchase, giving users permanent access to the Pro features after purchasing it.
