A free app for Android, by CpcTech Apps.
This app will help you easily copy and paste the codes directly to the clipboard, or you can also manually input them from the phone’s call dialer. If you ever lose the code and need to remember it, you can do that with this app.
The secret code book is designed to work on all devices that use the Android operating system. If you feel that this app is not working on your device, please send me an email so I can get in touch with you.
