Get the File from the Official Source

Open the APK File
Tap the APK file in your file manager or from the notification. Android will show an installation prompt listing what access the app is requesting.
Tap the "Install" Button
The "Install" button appears at the bottom of the prompt. Tap it and the installation will begin — it usually finishes within a few seconds.
Open the App

What to Do If Installation Fails

Storage IssueInstallation Is Being Blocked
If you see "Install blocked" or "For your security, your phone is not allowed to install unknown apps", go to Settings > Security > Unknown sources and allow APK installation. On some phones this option is under Privacy or Apps. After granting permission, tap the file again.
Security BlockApp Will Not Open
If the app crashes or will not open after installation, restart your phone first. If the problem continues, go to Settings > Apps > k333 key, clear the cache, and try opening the app again. This resolves the issue in most cases.
