How can I fix the Light setting button?

I accidentally dropped my Fujifilm Instax Mini 7s and it can still take pictures, but the button on top stayed onto the indoor setting, so I’m not able to take any pictures in the sun or shade, only when it is dark or indoors. It still takes pictures normally and I would like to take pictures in the sun again. Is there a possibility that it can be fixed or would I have to live with it ?
