I factory reset my Galaxy A10e then immediately install Ookla's Speed Test app. Over Wifi I get 100 to 200mbps on repeated tests. After installing basic mainstream apps like Spotify, Pandora, etc and updating Google's and the Samsung phone's preinstalled apps the Ookla Speed Tests give me a maximum speed of approx 30mpbs. I have to factory reset my phone and not install apps to keep the higher speed. What gives?
