Samsung Galaxy A11 constantly exchanging data on WiFi
I have two Samsung Galaxy A11's that were purchased September 2020, both fully updated. Since having these phones, both of themconstantly exchangedata when the phones are on WiFi. If I turn WiFI off, putting the phones on the T-Mobile network, this exchanging of data immediately stops. Lookout anti-virus is installed and the phones are virus-free. Is there a known reason why this has been occurring all this time, what they are connecting to (a Samsung server, perhaps?)and is there a way to stop it? Gracias.
