Abstract
M.Ing. (Electrical Engineering)
This dissertation is based on developing a mobile application by using an android studio with java programming language to detect incoming unsolicited Short Message Service (SMS) in mobile phones. The Application (APP) was developed and tested on android version 4.4 and 5.0. The results were good; and the App worked as expected. The App works in such a way that whenever there is an incoming SMS from a number which is not in the contact list, there will be room to either „allow‟ or „block‟ the incoming message from being delivered. If the user chooses to allow, the message will be delivered; and it would be accessible to the user, otherwise, the message will be blocked and not delivered; and such a contact cannot subsequently send an SMS to the mobile phone. It is believed that this App will enhance the experience of mobile-phones users; because the interface is user-friendly and easy to use.
