Common problems when installing APK games and applications
1. Error “App not installed”
Please take each of the following measures:
- If you get this error, you're probably installing a different version of the app you're trying to install. Please remove it first!
- It could also be because Play Protect is on, turn Play Protect off!
- This error can also happen because your device does not support this APK file.
- If you've done all of the above and it still doesn't fix the problem, try restarting the device!
2. Error “Download failed because you may not have purchased this app”
This error usually occurs for applications with OBB, it looks like you forgot to download OBB.
What if even after copying the OBB to the correct location, it still gives an error? Try to install the original version from Google Play first, then uninstall and reinstall with APK/OBB. There is a reputable apk file download website for you, which is Techtodown.
