i have a problem my Fiio X1 2nd gen after 2 days of usage i have a black screen and it wont turn on or off but will charge (the light changes) Does anyone know the solution.

Let the device run out of power (don’t charge until all lights are off) take out the micro SD card, then charge and power on before putting the card back in. Turning off Bluetooth should help aswell, so I recommend leaving it off until you need to use it, and turning Bluetooth off again before shutting off the device.
