Preparation Before Installing the APK

Before downloading and installing the 400k APK file, there are a few important steps you need to complete on your Android phone. These steps are straightforward and only need to be done once before your first installation. Getting the settings right will help you avoid any issues during the installation process.

Enable Unknown Sources

Since the 400k app is not distributed through the Google Play Store, you'll need to enable installation from external sources. Go to Settings > Security (or Settings > Apps > Unknown Sources depending on your phone model) and turn on the "Allow installation from Unknown Sources" toggle. On Android 8.0 and above, you may need to grant specific permission to the file manager or browser you used to download the APK.

Minimum System Requirements

  • Operating system: Android 6.0 (Marshmallow) or later
  • RAM: Minimum 2 GB (3 GB or above recommended)
  • Storage space: At least 150 MB of free space
  • Internet connection: Stable 4G / WiFi
  • Latest version of Android WebView (typically updated automatically)

Important Note: Once the 400k app is installed, you can turn off "Unknown Sources" again for added security. This is a recommended best practice for Android users in Malaysia.

Step-by-Step Installation Guide

Follow these five simple steps to install the 400k app on your Android phone.

1

Download APK File

Click the download button found in the app info section on this page. The official 400k APK file will automatically start downloading to your phone's "Downloads" folder. Make sure your internet connection is stable throughout the download to avoid a corrupted or incomplete file.

2

Installation typically takes less than a minute, depending on your device speed. A progress bar will show the installation status in real time. Do not close the screen or press the back button during this process to avoid an incomplete installation.

How to Update the APK to the Latest Version

Keeping the 400k app updated ensures you always have the latest features, bug fixes, and performance improvements. Updating the Android APK is straightforward and does not require you to uninstall the existing app first. You can update directly over the old version without losing any login data or saved preferences.

To update, download the latest APK file from this page when a new version is available. Once the download is complete, open the APK file and Android will detect that this is an update for an already-installed app. Follow the same installation steps as the first time and select "Install" when prompted. Once the update is done, reopen the 400k app and log in as usual to pick up right where you left off.

Tip: Check back on this page regularly to see if a new version of the 400k APK is available. The latest version typically includes security improvements and new game features.

Installation Issues & How to Fix Them

Quick fixes for common issues you may encounter when installing the 400k app.

Installation Blocked by Phone

If your phone shows an "Installation blocked" or "App not permitted" message, it means the "Unknown Sources" option has not been enabled. Go to Settings > Security and enable the option. On Android 8.0 and above, you may need to grant installation permission specifically to the browser or file manager app you are using to open the APK.

Corrupted or Incomplete APK File

If you get an "Invalid APK file" error or the installation stops midway, the downloaded file is most likely incomplete. This usually happens when your internet connection drops during the download. Delete the APK file and re-download it from this page using a more stable internet connection to get a complete file.

App Won't Open After Installation

If the 400k app crashes immediately after opening, try restarting your phone first. Also make sure your Android version is 6.0 or later and that Android System WebView has been updated via the Google Play Store. If the problem persists, try clearing the app's cache data by going to Settings > Apps > 400k > Storage > Clear Cache, then reopen the app.

Insufficient Storage Space

An "Insufficient storage" error means your phone needs more free space. Clear at least 200 MB by removing apps or files you no longer need before attempting to reinstall. You can also move photos and videos to an SD card or cloud storage to free up your phone's internal memory.
