The Screen of my wife’s Samsung M21 is broken and stays black but it still seems to recognize some touches (she can turn the Alarm off) I bought a USB Hub with a HDMI Port. When I plug in the phone via USB C nothing happens. The phone just vibrates briefly to indicate it’s charging. HDMI cable is connected to a monitor. Any tipps? She has no Samsung account, no find device Option or debugging activated. Phone is locked with pattern.
