Raspberry Pi Official 4 Power Adapter USB-C White
Is the device connected/wired correctly? On smartphones with the latest Android (Samsung), the yellow exclamation mark appears with a warning "Verify charger connection - Make sure the cable and charger are connected properly". I guess it shouldn't be because of the current delivery capability. With 3 amps!?!
This power supply is specially made for the Raspberry Pi 4 computer. It always supplies a voltage of 5.1V and is therefore not suitable for charging modern smartphones. These require a higher voltage (9V, 15V or 20V) via the USB-C interface in order to charge faster. This power supply does not support this function, so a warning appears. With 3 amps at 5V, it can achieve a maximum of 15W.
