Android je operačný systém vyvíjaný spoločnosťou Google, ktorý v súčasnosti používa väčšina výrobcov mobilných telefónov. Ide o tzv. otvorený operačný systém a má prakticky neobmedzené možnosti prispôsobenia. Niektoré úpravy je možné vykonať pomocou základných nastavení, zatiaľ čo ďalšie modifikácie si môžete kedykoľvek stiahnuť z obchodu Google Play. Používateľ tak môže veľmi jednoducho upravovať nielen grafické rozhranie, ale aj spôsob ovládania telefónu. Slabšou stránkou systému Android je jeho vyššia náchylnosť na napadnutie škodlivým softvérom. Podrobnejšie sa popisu jednotlivých OS, ich výhod a nevýhod venujem v článku Porovnanie mobilných operačných systémov.
