I have purchased 2 separate phones, both new recently, and both phones have had slow wifi speed. I've tested them on multiple wifi locations. My current phone has no problems. I've restarted phone, turned of app background usages, restarted router looked at settings. I'm baffled what am I missing. One phone was Motorola G power and the other was Samsung A14. Phone needed for medical device, so it has to be on the "list". Also is a 12 year old kid... trying not to put a 509+ $ phone in her hands. Any insight?
