Kali Linux is a powerhouse for cybersecurity enthusiasts, offering tools for penetration testing, ethical hacking, and network analysis. While it’s traditionally used on PCs, you can now run it on your Android device using Termux—no need for a laptop or complex setups. In this guide, I’ll walk you through the process step-by-step, ensuring you get Kali up and running smoothly.

What You’ll Need

1. An Android Device (Android 8.0 or higher): Older versions might work but aren’t recommended.
2. At least 4GB of Free Storage: Kali Linux and its tools require space.
3. A Stable Internet Connection: For downloading packages.
4. Termux (Installed via F-Droid): The Play Store version is outdated, so grab it from F-Droid.
5. Patience: The installation takes 15–30 minutes, depending on your internet speed.

Step 1: Install and Configure Termux

1. Download Termux from F-Droid:
   Open F-Droid, search for “Termux,” and install it. Avoid third-party sources to prevent security risks.
2. Update Packages:
   Launch Termux and refresh its package lists:

   pkg update && pkg upgrade -y  

Tap “Allow” if prompted for storage permissions.

3. Install Proot-Distro:
   This tool lets you run Linux distributions on Android:

   pkg install proot-distro -y  

Step 2: Install Kali Linux

1. Fetch Kali’s RootFS:
   Use proot-distro to install Kali:

   proot-distro install kali  

Confirm with Y when prompted.

2. Launch Kali Linux:
   Start the environment with:

   proot-distro login kali  

You’ll see a root@localhost prompt—you’re now inside Kali!

Step 3: Set Up Kali Tools

By default, Kali in Termux is minimal. Let’s add essential tools:

1. Update Kali’s Repositories:

   apt update && apt upgrade -y  

2. Install Core Packages:
   Grab the basics like nmap, wireless-tools, and the Kali menu:

   apt install kali-menu nmap git python3 -y  

3. Optional: Install a GUI (Graphical Interface):
   If you want a desktop experience:

• Install TigerVNC and XFCE4:
  apt install tigervnc-standalone-server xfce4 kali-defaults -y
• Start the VNC server:
  vncserver -localhost no
  Use a VNC viewer app (like bVNC) to connect to localhost:1.

Troubleshooting Common Issues

• “Command Not Found” Errors: Ensure you’re inside the Kali environment with proot-distro login kali.
• Storage Permission Denied: Grant Termux storage access in Android settings.
• VNC Connection Fails: Double-check your VNC server is running and the port is correct.

Ethical Reminder

Kali Linux is packed with powerful tools. Always use it ethically and only on networks/devices you own or have explicit permission to test. Unauthorized hacking is illegal!

FAQs

1. Does this require rooting?
   No! Termux uses a proot environment, so rooting isn’t necessary.
2. Will this harm my phone?
   Kali runs in an isolated environment, so your Android OS remains safe.
3. Can I uninstall Kali later?
   Yes! Just delete the Termux app or run:

   proot-distro remove kali  

Final Thoughts

Running Kali Linux on Android via Termux is a game-changer for on-the-go security testing. While performance depends on your device, it’s a handy way to practice ethical hacking or troubleshoot networks. Remember, with great power comes great responsibility—use Kali wisely!

We all want our phones to work faster, right? But buying a new phone isn’t always an option. The good news is, your Android phone has a hidden “developer mode” with settings that can speed things up. In this post, I’ll show you simple, safe tweaks to try—no tech skills needed!

What Are Developer Options?

Developer Options are advanced settings meant for app developers. They’re hidden by default because some options can be tricky, but a few changes here can make your phone feel snappier. Don’t worry—I’ll guide you through the safest ones.

Step 1: Turn On Developer Options

1. Open Settings > About Phone.
2. Find Build Number (usually at the bottom).
3. Tap the Build Number 7 times fast. You’ll see a message: “You’re now a developer!”

Step 2: Speed Up Your Phone

Now, go back to Settings > System > Developer Options. Try these tweaks:

1. Reduce Animations

Animations make your phone look smooth, but they slow things down.

• Tap Window Animation Scale, Transition Animation Scale, and Animator Duration Scale.
• Change each from 1x to 0.5x (or turn them off completely).
  Result: Apps and menus open faster!

2. Limit Background Apps

Too many apps running in the background can drain speed.

• Scroll to Background Process Limit.
• Select At most 4 processes (or fewer if you’re comfortable).
  Note: Don’t set this too low, or apps like messages might not work properly.

3. Force GPU Rendering

This uses your phone’s graphics power to handle apps better.

• Enable Force GPU Rendering.
  Good for: Older phones struggling with heavy apps like games.

4. Disable Automatic Updates

Background updates can slow your phone.

• Turn off Automatic system updates (if you see this option).
  Tip: Update apps manually when you’re not using the phone.

5. Turn Off Bloatware

Some pre-installed apps (bloatware) waste resources.

• Go to Running Services (under Developer Options).
• Tap apps you don’t use (like unused games or tools) and Stop them.
  Warning: Don’t stop apps you don’t recognize—they might be important!

Step 3: Restart Your Phone

After making changes, restart your phone. You’ll notice smoother scrolling, quicker app launches, and better performance overall.

What NOT to Do in Developer Options

• Avoid settings you don’t understand (like USB debugging or OEM unlocking).
• Don’t mess with Minimum width—it can break your screen layout.
• Never enable Force 4x MSAA unless you’re a gamer (it drains battery).

Extra Tips for Speed

• Clear app cache regularly (Settings > Storage > Cached Data).
• Uninstall apps you never use.
• Use “Lite” versions of apps like Facebook Lite or Messenger Lite.

Final Thoughts

Developer Options are like a secret toolbox for your phone. While these tweaks won’t turn an old phone into a flagship, they’ll definitely help it run smoother. Try one change at a time, and see what works best for you.

Remember: If something feels off, just go back to Developer Options and reset the settings. Your phone won’t explode—promise!
