Accumulated cache in the Android Package Installer is a frequently overlooked cause of the 1xBet app not installed error. Over time the Package Installer stores temporary data that can conflict with new APK installations, causing them to fail silently or display generic error messages.
To clear the Package Installer cache, open Settings on your Android device and tap Apps or Application Manager. Scroll through the list and find Package Installer. If it is not visible, tap the three-dot menu and select Show System Apps. Tap Package Installer, then tap Storage, and finally tap Clear Cache.

After clearing the cache, also tap Clear Data to reset the installer to a clean state. You will not lose any installed apps or personal data by doing this. Once complete, restart your device before attempting to install the 1xBet APK again.
If clearing the Package Installer cache alone does not resolve the issue, also clear the cache for Google Play Services. Go to Settings → Apps → Google Play Services → Storage → Clear Cache. Google Play Services handles many background installation tasks and a corrupted cache can interfere with APK installations.
For devices running Android 9 or earlier, you may also need to clear the cache partition from recovery mode. Power off the device, then hold the Volume Up and Power buttons simultaneously to enter recovery. Select Wipe Cache Partition using the volume keys and confirm with the power button. This clears system-level cached data without affecting your files.
