How to Install the 01 Game APK on Your Android Device

Installing an APK file manually is simple. Just follow these steps:

1. Locate the Downloaded File

• Open your phone’s File Manager app (also called “Files,” “My Files,” or similar).

• Go to the Downloads folder (or wherever your browser saves files).

• Find the file named 01 Game.apk.

2. Start the Installation

• Tap once on the 01 Game.apk file to begin.

3. Handle Security Prompt (If It Appears)

Since the app isn’t from the Play Store, your phone might block it at first.

• You may see a message like:
  “For your security, your phone is not allowed to install unknown apps from this source.”

• If this happens:

  • Tap Settings or Allow on the prompt.

  • You’ll be taken to a system screen.

  • Find the app you’re using (like your File Manager or browser), and toggle “Allow from this source” ON.

• Note: This only allows that one app (File Manager or browser) to install APKs—not every app.

Then tap the back button to return to the installation screen.

4. Confirm Installation

• You’ll now see a screen asking if you want to install 01 Game.

• (Optional) Review the permissions the app requests.

• Tap Install.

5. Wait for Installation

• A progress bar will show the installation status.

• This usually takes just a few seconds.

6. You’re Done!

• Once installed, you’ll see a message:
  “App installed”

• You can choose:

  • Open – to launch the app now.

  • Done – to exit the installer.

7. (Optional but Recommended) Turn Off “Unknown Sources”

• For added safety, you can go back to:
  Settings → Apps → Special App Access → Install Unknown Apps

• Find the app (like your File Manager), and turn “Allow from this source” back OFF.
