Samsung has this on some phones called intelligent wi-fi... https://docs.samsungknox.com/admin/knox-platform-for-enterprise/kbas/kba-360034073174/ https://docs.samsungknox.com/admin/knox-platform-for-enterpr... >Intelligent Wi-Fi provides four features that aim to improve consumers’ Wi-Fi experience: Network Bearer Switching Auto Wi-Fi Suspicious Hotspot Detection Enhanced Power Saving >Intelligent Wi-Fi is the new brand name of the existing “Adaptive Wi-Fi” which had been applied to models older than Galaxy S10 (e.g. Galaxy S9 or older models). It has been improved by adding a new feature such as Suspicious Network Detection and also enhancing existing features such as Network Bearer Switching. >Auto Wi-Fi >People use Wi-Fi differently based on their location. In places where Wi-Fi is available, we turn on Wi-Fi to avoid being charged for mobile data. On the other hand, if Wi-Fi is always on, we are subjected to frequent, unwanted connections and higher power consumption. To solve this problem, we have introduced Auto Wi-Fi, which turns Wi-Fi on and off depending on your location. Auto Wi-Fi addresses these connectivity-related pain points. >Auto Wi-Fi pays close attention to your connection patterns and remembers your favorite networks. It turns your Wi-Fi on when a favorite network is available. When you leave the area and the network becomes unavailable, Auto Wi-Fi will automatically turn off your Wi-Fi.
