Allowing App Installation from Downloaded Files on Android
Seeing a message about "unknown sources" when installing 1xBet? This page explains what it means and how to enable it safely on your Android phone.
Quick Setup (Most Android Phones)
- Tap the downloaded APK file
- When prompted, tap "Settings"
- Enable "Allow from this source"
- Go back and tap "Install"
Takes about 30 seconds. Detailed steps for different phones below.
Why Does Android Block Some Installations?
Android protects your phone from accidental app installs. When an app comes from outside Google Play, the phone asks for your permission first.
What Triggers the Block
| App Source |
Android Response |
| Google Play Store |
Installs automatically (no extra permission) |
| Downloaded APK file |
Asks for "unknown sources" permission |
| App from browser |
Asks for browser permission |
| File from messaging app |
Asks for that app's permission |
This is Normal Behavior
- Happens with all APK files, not just 1xBet
- It's a safety feature, not a warning about danger
- You control which sources can install apps
- Can be turned off after installing
→ Continue with installation: Installing 1xBet APK
What Does "Allow From This Source" Mean?
This option gives permission to install apps from one specific place — like your browser or file manager.
Key Points
- Source = where you opened the file from (Chrome, Files, WhatsApp, etc.)
- Permission is per-app — allowing Chrome doesn't allow other apps
- You can disable it later — go to Settings anytime
- Doesn't affect Play Store — Play Store works normally
Example Scenarios
| How You Downloaded |
Source Name |
What Gets Permission |
| Chrome browser |
Chrome |
Only files from Chrome |
| File Manager app |
Files / My Files |
Only files opened in Files |
| WhatsApp |
WhatsApp |
Only files from WhatsApp |
| UC Browser |
UC Browser |
Only files from UC Browser |
Good to know: If you downloaded with Chrome, you only give Chrome permission. Other apps still can't install anything without your approval.

Yes, when the file comes from a trusted source. The setting itself doesn't make your phone unsafe.
