Hamsteroon

Before you can install Hamsteroon  on your phone you will need to make sure that third-party apps are allowed on your device. Go to Menu > Settings > Security > and check Unknown Sources to allow your phone to install apps from sources other than the Google Play Store. Android 8.0 Oreo does things a little differently. Rather than check a global setting to allow installation from unknown sources, you'll be you'll be prompted to allow your browser or file manager to install APKs the first time you attempt to do so.
