Same for me in regards to the iPhone red issue. This is prior to updating to iOS 14 beta, but microphone has been broken for a while, phone will not record videos with sound, only way I am able to make phone calls is by bluetooth headphones such as airpods. In regards to the issue after updating to the beta, I do not own a battery case, never used one, and earlier today safari was working perfectly, then I updated to the beta software, and safari does not work any longer, even after cold and hard restarts, clearing browsing data, and any other troubleshooting methods. Have not been able to figure out a possible fix.
