Google Play Protect is Android's built-in security scanner that checks apps for harmful behavior before and after installation. Because 1xBet is a gambling application distributed outside the Play Store, Play Protect may flag it as potentially harmful and block the installation, resulting in the app not installed error.
To disable Google Play Protect temporarily, open the Google Play Store app on your Android device. Tap your profile icon in the top right corner, then select Play Protect from the menu. Tap the gear icon in the top right of the Play Protect screen to access settings.

On the Play Protect settings screen, toggle off Scan apps with Play Protect. You will see a warning from Google; tap Turn Off to confirm. Now attempt to install the 1xBet APK again. The installation should proceed without being blocked.
After successfully installing 1xBet, it is strongly recommended to re-enable Play Protect to keep your device protected from genuinely malicious applications. Return to Play Store → Profile → Play Protect → Settings and toggle Scan apps with Play Protect back on.
If Play Protect continues to block the installation even after being disabled, the APK file itself may have been flagged. Delete the downloaded file, clear your browser cache, and re-download the APK from the official 1xBet website on a fresh connection. Avoid any third-party mirror sites that may distribute modified versions.

Play Protect is an important security layer, so always re-enable it once the 1xBet installation is complete. Only disable it temporarily for the duration of the installation process.
