My galaxy S5's screen was broken/complete dark but the power is still functional. I need to transfer the data to a new phone. So i bought a device "HDMI adapter & OTG card reader" that can be connected to tv and usb mouse. I tried using it, the cellphone home screen appeared on tv but the mouse was not detected. The mouse arrow was not showing on the t.v. Screen. I tried using several usb mice but having the same problem. I won't be able to transfer my data until I unlock the pin. Please give me any advice/suggestion about the mouse. Thanks so much.
