In general, all 4x samples should work fine on a wide variety of mobile devices. That is one of the main advantages of using the 4x version of the API over the 3x version. The only recommendations we have are the system requirements, which help indicate the hardware and software (including mobile) we recommend: System Requirements | ArcGIS API for JavaScript 4.15
