I have iPhone XS and my husband has iPhone 8 both are running iOS 14.3 - WiFi constantly drops out and reverts to 4g. It’s infuriating. Our daughter has a Google Android phone - and is experiencing no problems so this suggests it’s the iPhone rather than our WiFi. We all simultaneously tried to load several webpages today - the iPhones failed miserably taking anything from 30 seconds to 4 minutes to load successfully and sometimes just not loading at all - the android loaded within 10 seconds every time. Seriously considering moving away from iPhone
