I know some C++ basics (able to create a simple "game" using SFML library where you should click squares and they respawn back, that kinda level) and have a decent knowledge of web development (html,css,js,php).
My question is how hard would be the learning curve for me? I would like to create a simple app where you can toggle your maximum mobile data speed (2G / 3G / 4G) just with simple switch buttons. Is it even possible to access and modify system settings in the latest Windows Phone version? What should be the code, setup, how the layout works, etc. Point me in the right direction!
