When I originally bought my 20 Passport, I owned a galaxy s9+ phone. I plugged it into the USB charger under the dashboard (in order to use Android Auto) and was getting fast charging to work. Now I replaced my phone with the new S21 and still the same plug and cable. The difference now is that it will slow (cable charge) and I believe that's why I see the "red box" around the phone charging symbol on the screen. Anyone else noticed this?
