KSigned APKs do work on all Android devices (rooted + non-rooted).
Signed APKs are in the most cases the only provided files by the mod publisher as they work for everyone.
1.) Remove the original game/app.
2.) Download the MOD APK.
3.) Install the downloaded MOD APK.
4.) Enjoy.
Google login possible? No.
Facebook login possible? Yes. But you have to remove the Facebook App from your device.
Specific game account login possible (for example: E-Mail, HIVE, Kakao)? Yes.
Notes:
- If you used our MOD APK before and just want to update, you can install the new MOD APK on top of the old without removing the game/app first.
- In-App purchases are not possible on signed APKs as they require Google services similar to the Google login process.
