There was a workaround with the 5G signal, you know that nice looking ‘window’ in the iPhone frame, from what I heard heat is a big problem with 5G, the real issue is that 5G is not ready, wifi 6 is powered from 5G or high gigabit fiber, however wifi 6 is only clocked at 6hz freq, aluminum and SS work but try holding your phone after extensive use...sub 6 5G is also a workaround until they get mmwave in play, in order for this to happen, technology has to make that leap. This is the reality we live in.
