Vincent has a bunch of Samsung S20 phones for his business and would like to move away from Android. Is there an operating system that he can install over it? Leo says that Samsung has taken Android and modified it greatly. There are other flavors of Android you can put on it by rooting the device, but they are still Android. But you can "De-Google" it. Leo recommends going to XDA-Developers. Search for the model number of your phone and see what ROMs are available and how to put them on your phone.
