The Digital Controls Android app can be downloaded from Google Play. Since May 2020, some smartphone models are no longer certified by Google, so they no longer use Google Mobile services and therefore Google Play. The Digital Controls app uses a set of Google services to function, so it is not compatible with another universe of applications and services. The models for which our application is not compatible are: Huawei P40 Huawei P40 Lite Huawei P40 Lite 5G Huawei P40 Lite E Huawei P40 Pro+ Huawei P40 Pro Huawei Mate 30 Pro Huawei Mate 30 Honor 9X Pro Honor View 30 Pro Honor View 30
